  • getting data from tableviewcell to 2nd view

    - by chubsta
    I am very new to this and am trying to learn by creating a few little apps for myself. I have a navigation-based app where the user taps the row to select a film title - i then want the second view to show details of the film. Thanks to a very helpful person here i am getting the results of the row pressed as 'rowTitle' as follows : (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *key = [keys objectAtIndex:indexPath.section]; NSArray *nameSection = [names objectForKey:key]; NSString *rowTitle = [nameSection objectAtIndex:indexPath.row]; NSLog(@"rowTitle = %@", rowTitle); [tableView deselectRowAtIndexPath:indexPath animated:YES]; I am, however, struggling to make the data at 'rowTitle' available to the 2nd view - basically, if i can get the info - for example rowTitle is "aliens2" - i want to be able to add a new extension to the end of the string returned by 'rowTitle' in order to point to an image (if that makes sense) in the second view... something like tempImageName=[** this is where the info from rowTitle needs to be i suppose**]; tempImageType=@".png"; finalImageName=[tempImageName stringByAppendingString:tempImageType]; does this make sense to anyone (apologies if it doesnt - i know what i want but how to explain it is a little more awkward!) Thanks again for any help anyone can give (and any help as to formatting these questions would be useful too obviously!!)!

  • UIAlertView choice causing resignFirstResponder to fail

    - by Chazbot
    Hi everyone. I'm having a similar issue to Anthony Chan's question, and after trying every suggested solution, I'm still stuck. Somehow, only after interacting with my UIAlertView, I'm unable to dismiss the keyboard in another view of my app. It's as though the Alert is breaking my UITextField's ability to resignFirstResponder. Below I instantiate my UIAlertView, which then calls its didDismissWIthButtonIndex method. Then, I call the showInfo method, which loads another UIViewController. UIAlertView *emailFailAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"error message text." delegate:self cancelButtonTitle:@"Not now" otherButtonTitles:@"Settings", nil]; [emailFailAlert setTag:2]; [emailFailAlert show]; [emailFailAlert release]; Once the 'Settings' option is pressed, I'm calling this method: - (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { if ([alertView tag] == 2) { if (buttonIndex == 1){ [self showInfo:nil]; } } } My showInfo method loads the other ViewController, via the code below: - (IBAction)showInfo:(id)sender { FlipsideViewController *fscontroller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; fscontroller.delegate = self; fscontroller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:fscontroller animated:YES]; [fscontroller release]; } Upon clicking any textField in this Flipside VC, I'm unable to dismiss the keyboard as I normally can with - (BOOL)textFieldShouldReturn:(UITextField *)textField, and [textField resignFirstResponder]. I've omitted this code bc this question is getting long, but I'm happy to post if necessary. The interesting part is that if I comment out the [self showInfo:nil] call made when the button is clicked and call it by clicking a test button (outside the alertView didDismissWithButtonIndex: method), everything works fine. Any idea what's happening here? Thanks in advance!

  • Really cool way to create custom UITabBar for iPhone app?

    - by ludicco
    Hi, I am doing a lot of researching lately about how to get a different looking with nice effects UITabBar on my iPhone app, but unfortunately I am only finding things on how to replace background color etc. Well, I've checked out this app called Momento which is pretty cool and presents a very slick tabBar: So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :) Arrow above items: as you can see this app has this animated arrow that runs above the selected item with a very smooth animation. Selected Stated of the item's image is not that blue-ish default one neither the default state which displays in a different shade of brown and gray version. nice Items separators with beveled vertical lines. diferrent background image for the tabBar different height for the tabBar At this point after some research I am able to set the height and background image by subclassing UITabBarController but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect. If someone knows about a very good tutorial on how to do this it would be great for clarifying what can or can't be done by subclassing the UITabBarController and specially if can be done in Interface Builder :) I am just starting on this world off app development for iOS so if you could help me on that it would be really appreciated Thanks a lot in advance

  • How to move from custom to transluscent NavigationBar and back? Display problems!

    - by jd291
    So, i got this Navigation-based App (with a custom NavigationBar - Category) and I have 2 problems here... @implementation UINavigationBar (Custom) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"bg_toolbar.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end Because of the Navigation-based App, most of the views have a height of 436px (= ScreenSize - NavigationBar height, as you probably know ;). I got one view similar to the photo app overview showing all the thumbnails, from there I push a viewcontroller containing the scroll view (like in photos app) on the stack, like so - (void)buttonPressed:(id)sender { UIButton *btn = (UIButton *)sender; PhotoSetScrollViewController *psc = [[PhotoSetScrollViewController alloc] initWithPhotoArray:photos andID:btn.tag]; [self.navigationController pushViewController:psc animated:YES]; } Problem 1: The view holding the fullscreen scrollview has a height of 480px which seems to be a problem because when poping the viewcontroller by hitting the back button, the view containing the thumbnails (height 436px) moves upward below the navigation bar. And also the Toolbar keeps showing. What could be the problem? Problem 2: How could I switch between my custom navigation bar and the standard black translucent style?

  • cancelPreviousPerformRequestWithTarget is not canceling my previously delayed thread started with pe

    - by jmurphy
    Hello, I've launched a delayed thread using performSelector but the user still has the ability to hit the back button on the current view causing dealloc to be called. When this happens my thread still seems to be called which causes my app to crash because the properties that thread is trying to write to have been released. To solve this I am trying to call cancelPreviousPerformRequestsWithTarget to cancel the previous request but it doesn't seem to be working. Below are some code snippets. - (void) viewDidLoad { [self performSelector:@selector(myStopUpdatingLocation) withObject:nil afterDelay:6]; } (void)viewWillDisappear:(BOOL)animated { [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(myStopUpdatingLocation) object:nil]; } Am I doing something incorrect here? The method myStopUpdatingLocation is defined in the same class that I'm calling the perform requests. A little more background. The function that I'm trying to implement is to find a users location, search google for some locations around that location and display several annotations on the map. On viewDidLoad I start updating the location with CLLocationManager. I've build in a timeout after 6 seconds if I don't get my desired accuracy within the timeout and I'm using a performSelector to do this. What can happen is the user clicks the back button in the view and this thread will still execute even though all my properties have been released causing a crash. Thanks in advance! James

  • How do I push another viewController onto the navigationController from within a tabviewController?

    - by user207788
    Hi, I have a project set up using these two tutorials. http://twilloapp.blogspot.com/2009/03/how-to-embed-navigation-controller.html and the link for the second tutorial is at the bottom of the first. The tutorial is slightly outdated but I managed to get it to work as advertised. Now I want to push a new detailedView onto the NavigationController when a user touches a row in the table view. So I added this to my MyTableViewController.m file. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. SecondViewController *detailViewController = [[SecondViewController alloc] initWithNibName:@"SecondViewController.xib" bundle:nil]; // ... // Pass the selected object to the new view controller. [self.navigationController pushViewController:detailViewController animated:YES]; [detailViewController release]; } Now when I run this project and touch a row in my table view I am getting an error: asm_Terminating_due_to_uncaught_exception IT seems to be having an issue loading the SecondViewController from nib, however I checked the detailViewController and it is not nil. I know I am missing something and it is more than likely something simple. Please help. Thanks, Bruce

  • Initializing Detail View from nib with parameters passed from Root View

    - by culov
    I'm have a map view with a number of annotations on it... once the callout is clicked, i need to pass several parameters to the DetailViewController, so ive been trying to do this through the constructor. I've debugged a bit and discovered that the arguments are being passed properly and are being received as expected within the constructor, but for some reason whenever I try to change the values of the IBOutlets I've positioned in the nib, it never has an effect. Here's what im passing (btw, im getting a "No initWithNibName : bundle : header' method found" warning at this line): DetailViewController *dvc = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil header:headerText]; [self.navigationController pushViewController:dvc animated:YES]; Now heres my constructor: - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil header:(UILabel*)headerLabel { if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { self.headerTextView = headerLabel; NSLog(@"header:%@", headerLabel.text); } return self; } Once again, the problem is that headerLabel.text is printed properly in the console, but the line self.headerTextView = headerLabel; doesnt seem to be doing what I want it to do. Thanks!

  • Graphical glitches when adding cells and scrolling with UITableView

    - by Daniel I-S
    I am using a UITableView to display the results of a series of calculations. When the user hits 'calculate', I wish to add the latest result to the screen. This is done by adding a new cell to a 'results' section. The UITableViewCell object is added to an array, and then I use the following code to add this new row to what is displayed on the screen: [thisView beginUpdates]; [thisView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation: UITableViewRowAnimationFade]; [thisView endUpdates]; This results in the new cell being displayed. However, I then want to immediately scroll the screen down so that the new cell is the lowermost cell on-screen. I use the following code: [thisView scrollToRowAtIndexPath:newIndexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES]; This almost works great. However, the first time a cell is added and scrolled to, it appears onscreen only briefly before vanishing. The view scrolls down to the correct place, but the cell is not there. Scrolling the view by hand until this invisible new cell's position is offscreen, then back again, causes the cell to appear - after which it behaves normally. This only happens the first time a cell is added; subsequent cells don't have this problem. It also happens regardless of the combination of scrollToRowAtIndexPath and insertRowsAtIndexPath animation settings. There is also a problem where, if new cells are added repeatedly and quickly, the new cells stop 'connecting up'. The lowermost cell in a group is supposed to have rounded corners, and when a new cell is added these turn into square corners so that there is a clean join with the next cell in the group. In this case, however, a cell often does not lose its rounded edges despite not being the last cell anymore. This also gets corrected once the affected area moves offscreen and back. This method of adding and scrolling would be perfect for my application if it weren't for these weird glitches. Any ideas as to what I may be doing wrong?

  • pushing view controller inside a tab bar from app delegate, after a notification.

    - by shani
    hi i have an app with tab bar and a navigation controller inside every tab. i have set a notification that when it lunches the user can get lunch the app by pressing the action on the alert. i want to redirect the user to one of the views inside one of the controllers. i have tried this: (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif { NSArray *data = [notif.userInfo objectForKey:@"todoDate"]; NSInteger ind = [[data objectAtIndex:2] integerValue]; QuickViewController *detailViewController ; detailViewController = [[QuickViewController alloc] initWithNibName:@"QuickViewController" bundle:nil]; detailViewController.title = @"Edit"; detailViewController.personName = [data objectAtIndex:0]; detailViewController.DelitionDate=[data objectAtIndex:1]; detailViewController.personCategory=@"NO Category"; detailViewController.personID = ind r ; rootControler.selectedIndex = 1; [rootControler.tabBarController.selectedViewController.navigationController pushViewController:detailViewController animated:YES]; } but nothing is happening (no crashing) except of the :rootControler.selectedIndex = 1; when i tried : presentModalViewController i got the view perfectly but without the navigation controller. thanks shani

  • Why am I getting "Message sent to deallocated instance" in Objective-C?

    - by Dave C
    I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag (int value) is parsed into the controller's house ID. It works with one of the buttons — the first one created, to be specific — but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code. I haven't set them to autorelease or anything like that. I'm just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++;

  • How to set interface method between two viewController to pass paramter in Navigation Controller

    - by TechFusion
    Hello, I have created Window based application, root controller as Tab Bar controller. One Tab bar has Navigation controller. Navigation controller's ViewControlller implementation, I am pushing Viewcontroller. I am looking to pass parameter from Navigation Controller's View controller to pushed View Controller. I have tried to pass as per below method. //ViewController.h @interface ViewController:UIViewController{ NSString *String; } @property(copy, nonatomic)NSString *String; @end //ViewController.m #import "ViewController1.h" ViewController1 *level1view = [[ViewController alloc]init]; level1view.hideBottomBarWhenPushed = YES; level1view.theString = String; [self.navigationController pushViewController:level1view animated:YES]; [level1view release]; //ViewController1.h NSString *theString; @property(copy, nonatomic)NSString *theString; This is working fine. but I want to pass more than one parameter like Integer and UITextFiled Values so how to do that? Is there any Apple Doc that I can get idea about this? Thanks,

  • Unable to pass variables from one view to another

    - by jerincbus
    I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.address = self.address; mapController.Title = self.Title; mapController.lat = self.lat; mapController.lng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; mapController = nil; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

  • delegate method throws runtime "unrecognized selector" error when switching back from one UIViewCont

    - by chimgrrl
    Ok, I've spend like half day on this and it's killing me. So I've got 3 view controllers transitioning from one another, something like this: I call the UploadDecisionViewController after destroying the previous View Controller: [self dismissModalViewControllerAnimated:YES]; [self performSelector:@selector(showUDModalView) withObject:nil afterDelay:0.5]; In my showUDModalView method: - (void)showUDModalView { UploadDecisionViewController *udcontroller = [[UploadDecisionViewController alloc] initWithNibName:@"UploadDecisionViewController" bundle:nil]; udcontroller.delegate = self; [self presentModalViewController:udcontroller animated:YES]; [udcontroller release]; } The UploadDecisionViewController shows up no problem. The UploadDecisionViewController has a button, which when clicked I want it to transition to the FileUploadViewController. I setup a UploadDecisionDelegate, threw a method in there to handle the button clicking: Inside UploadDecisionDelegate protocol (UploadDecisionViewController.h): @protocol UploadDecisionDelegate //let UOnliveViewController know that a button was selected - (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection; @end Then inside my IBAction method when the button is clicked, I have this: - (IBAction)decisionSelected:(id)sender { [delegate UploadDecisionViewController:self madeChoice:@"upload"];//crashing at this line } When I run this, at this line above it is throwing a runtime exception: 2010-06-09 12:48:59.561 UOnlive[4735:207] *** -[UIView UploadDecisionViewController:madeChoice:]: unrecognized selector sent to instance 0x3b65420 2010-06-09 12:48:59.562 UOnlive[4735:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView UploadDecisionViewController:madeChoice:]: unrecognized selector sent to instance 0x3b65420' 2010-06-09 12:48:59.563 UOnlive[4735:207] Stack: ( 33502299, 2495698185, 33884219, 33453686, 33306306, 20618, 2982917, 3390286, 3399023, 3394235, 3087839, 2996168, 3022945, 40156505, 33287040, 33283144, 40150549, 40150746, 3026863, 11700, 11554 ) Let me throw in the delegate method implemented also: - (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection { NSLog(@"it got to here 245"); [self dismissModalViewControllerAnimated:YES]; if (yesOrNo) { //open up the FileUploadViewController and proceed to upload [self performSelector:@selector(showFUModalView) withObject:nil afterDelay:0.5]; } } Can someone tell me what the heck is going on?

  • Displaying modal view in Objective-C

    - by kpower
    I'm trying to display Modal View in my app. I have subclass of UIViewController that has only the "Done" button (UIButton created with IB and linked with XCode). .h @interface myModalVC : UIViewController { UIButton *bDone; } @property (nonatomic, retain) IBOutlet UIButton *bDone; - (IBAction)bDoneTouchDown:(id)sender; @end .m #import "myModalVC.h" @implementation myModalVC @synthesize bDone; - (void)dealloc { [bDone release]; [super dealloc]; } - (void)viewDidLoad { [super viewDidLoad]; } - (void)viewDidUnload { } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (UIInterfaceOrientationLandscapeLeft == interfaceOrientation || UIInterfaceOrientationLandscapeRight == interfaceOrientation); } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (IBAction)bDoneTouchDown:(id)sender { [self.parentViewController dismissModalViewControllerAnimated:YES]; } @end I'm trying to display modal view with this code (from my main view): myModalVC *temp = [[[myModalVC alloc] initWithNibName:@"myModalVC" bundle:[NSBundle mainBundle]] autorelease]; [self presentModalViewController:temp animated:YES]; If this code is placed in some method, that responds to button touches - everything is fine. But when I place it to some other method (called during some processes in my app) - modal view is displayed without problems, but when I press (touch) "Done" button, application crashes with "Program received signal: “EXC_BAD_ACCESS”." What am I doing wrong?

  • Xcode: Display Login View in applicationDidBecomeActive

    - by Patrick
    In my app I would like to show a login screen - which will be displayed when the app starts and when the app becomes active. For reference, I am using storyboards, ARC and it is a tabbed bar application. First off, I have this method which returns the topViewController. - (UIViewController *)topViewController:(UIViewController *)rootViewController { if (rootViewController.presentedViewController == nil) { return rootViewController; } if ([rootViewController.presentedViewController isMemberOfClass:[UINavigationController class]]) { UINavigationController *navigationController = (UINavigationController *)rootViewController.presentedViewController; UIViewController *lastViewController = [[navigationController viewControllers] lastObject]; return [self topViewController:lastViewController]; } UIViewController *presentedViewController = (UIViewController *)rootViewController.presentedViewController; return [self topViewController:presentedViewController]; } And I call this method here: - (void)applicationDidBecomeActive:(UIApplication *)application { if ( ... ) { // if the user needs to login PasswordViewController *passwordView = [[PasswordViewController alloc] init]; UIViewController *myView = [self topViewController:self.window.rootViewController]; [myView presentModalViewController:passwordView animated:NO]; } } To an extent this does work - I can call a method in viewDidAppear which shows an alert view to allow the user to log in. However, this is undesirable and I would like to have a login text box and other ui elements. If I do not call my login method, nothing happens and the screen stays black, even though I have put a label and other elements on the view. Does anyone know a way to resolve this? My passcode view is embedded in a Navigation Controller, but is detached from the main storyboard.

  • iOS - Passing variable to view controller

    - by gj15987
    I have a view with a view controller and when I show this view on screen, I want to be able to pass variables to it from the calling class, so that I can set the values of labels etc. First, I just tried creating a property for one of the labels, and calling that from the calling class. For example: SetTeamsViewController *vc = [[SetTeamsViewController alloc] init]; vc.myLabel.text = self.teamCount; [self presentModalViewController:vc animated:YES]; [vc release]; However, this didn't work. So I tried creating a convenience initializer. SetTeamsViewController *vc = [[SetTeamsViewController alloc] initWithTeamCount:self.teamCount]; And then in the SetTeamsViewController I had - (id)initWithTeamCount:(int)teamCount { self = [super initWithNibName:nil bundle:nil]; if (self) { // Custom initialization self.teamCountLabel.text = [NSString stringWithFormat:@"%d",teamCount]; } return self; } However, this didn't work either. It's just loading whatever value I've given the label in the nib file. I've littered the code with NSLog()s and it is passing the correct variable values around, it's just not setting the label. Any help would be greatly appreciated. EDIT: I've just tried setting an instance variable in my designated initializer, and then setting the label in viewDidLoad and that works! Is this the best way to do this? Also, when dismissing this modal view controller, I update the text of a button in the view of the calling ViewController too. However, if I press this button again (to show the modal view again) whilst the other view is animating on screen, the button temporarily has it's original value again (from the nib). Does anyone know why this is?

  • How should I properly format this code?

    - by ct2k7
    Hi, I've a small issue here. I am using an if statement with UIAlertView and I have two situations, both result in UIAlertViews. However, in one situation, I want to dismiss just the UIAlertView, the other, I want the UIAlertView to be dismissed and view to return to root view. This code describes is: if([serverOutput isEqualToString:@"login.true"]){ [Alert dismissWithClickedButtonIndex:0 animated:YES]; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; UIAlertView *success = [[UIAlertView alloc] initWithTitle:@"Success" message:@"The transaction was a success!" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil]; [success show]; [success release]; } else { UIAlertView *failure = [[UIAlertView alloc] initWithTitle:@"Failure" message:@"The transaction failed. Contact sales operator!" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil]; [failure show]; [failure release]; } } -(void)alertView: (UIAlertView *)success clickedButtonAtIndex: (NSInteger)buttonIndex{ switch(buttonIndex) { case 0: { [self.navigationController popToRootViewControllerAnimated:YES]; } } } So, in both cases, they follow the above action, but obviously, that's not what I want. Any ideas on what I do here?

    Hi All, today I've come across a rather weird issue. After adding code to validate a key (i added it below), the Simulator refuses to let go of the old plist file. I deleted the simulator folder in the Application Support folder, then deleted the *build directory and restarted xcode & build & run my app...still the same issue. the old plist is still there and 100% identical. I then changed the identifier and the snippet's validation keys, the plist however stayed the same. basically, no matter what i do it won't go. the same thing happens on the iphone itself. I have checked through the code, i don't create the key anywhere, but it still returns YES for it at every restart. Here's the code I added: + (void)initialize{ ////////////////////////////SPECIFING THE PREDATA/////////////////// NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSDictionary *appDefaults = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:NO] forKey:@"protect"]; [defaults registerDefaults:appDefaults]; } if ([[NSUserDefaults standardUserDefaults] boolForKey:@"protect"] == NO) { [navigationController pushViewController:help animated:YES]; [help.navigationItem hidesBackButton]; } else { [window addSubview:passcode.view]; [self performSelector:@selector(responder) withObject:nil afterDelay:1]; } as a result, it will always go for the else option, which for some reason, doesn't get executed either. I assumed an error but the log is empty and there's no crash.

  • iOS 6 Rotation issue - No rotation from Presented Modal View Controller

    - by hart1994
    I have a MainViewController which has a button which pushes a new view (InfoViewController), via flip horizontailly. like so: controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; The MainView Controller supports Portrait and PortraitUpsideDown. Like so: - (BOOL)shouldAutorotate { return YES; } - (NSUInteger)supportedInterfaceOrientations { return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown); } In my InfoViewController it also states the above code. In my AppDelegate it has this in the LaunchOptions: [self.window setRootViewController:self.mainViewController]; In my app.plist file it supports all orientations. This is because other views need to support landscape as well. So On my MainViewController and InfoViewController I need only Portrait and PortraitUpsideDown. But on another view I need all orintations. My MainViewController works fine, but my InfoViewController is working for all orientations. I am having extreme diffulty trying to get this to work in iOS6. I have researched other posts and tried the assistance other people have provided, but had no luck whatsoever. Please can someone help me acheive this thank you. And I'm a Objective-C newbie :p

  • UINavigationController not working under ARC in iPhone

    - by user1811427
    I have creared a new project "Empty Application" template in Xcode 4.3, it is having only two classes AppDelegate.h & .m I cheaked with ARC to use automatic reference count while creating the app. I added two new files "RootViewController" & "NewProjectViewControllers". I implemented code to set navigation controller as follows in AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. rootViewController = [[MainViewController alloc] init]; UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:rootViewController]; [self.window addSubview:navigation.view]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } and in hte home view (Root view controller) implemented as follows - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Projects"; UINavigationBar *navigationBar = [self.navigationController navigationBar]; [navigationBar setTintColor: [UIColor colorWithRed:10/255.0f green:21/255.0f blue:51/255.0f alpha:1.0f]]; //To set the customised bar item UIButton *rightBarBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [rightBarBtn setBackgroundImage:[UIImage imageNamed:@"plus_new.png"] forState:UIControlStateNormal]; rightBarBtn.frame=CGRectMake(0.0, 100.0, 30.0, 30.0); [rightBarBtn addTarget:self action:@selector(addProject) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem* rightBarItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarBtn]; self.navigationItem.rightBarButtonItem = rightBarItem; // Do any additional setup after loading the view from its nib. } - (void) addProject { NewProjViewController *editProject = [[NewProjViewController alloc] init]; [self.navigationController pushViewController:editProject animated:YES]; NSLog(@"xxxxxxxxxxxxxxx"); } But since i used ARC the navigation may dealoc immediately and it doesn't work, All the actions in method works except push to the next view if i do same thing with out ARC it works fine How to resolve this issue..? Thanks in advance

  • UITableView cell appearance update not working - iPhone

    - by Jack Nutkins
    I have this piece of code which I'm using to set the alpha and accessibility of one of my tables cells dependent on a value stored in user defaults: - (void) viewDidAppear:(BOOL)animated{ [self reloadTableData]; } - (void) reloadTableData { if ([[userDefaults objectForKey:@"canDeleteReceipts"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; } else { NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } if ([[userDefaults objectForKey:@"canDeleteMileages"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:1 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; } else { NSIndexPath *path = [NSIndexPath indexPathForRow:1 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } if ([[userDefaults objectForKey:@"canDeleteAll"] isEqualToString:@"0"]) { NSIndexPath *path = [NSIndexPath indexPathForRow:2 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 0.2; cell.userInteractionEnabled = NO; NSLog(@"In Here"); } else { NSIndexPath *path = [NSIndexPath indexPathForRow:2 inSection:8]; UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:path]; cell.contentView.alpha = 1; cell.userInteractionEnabled = YES; } } The value stored in userDefaults is '0' so the cell in section 8 row 2 should be greyed out and disabled, however this doesn't happen and the cell is still selectable with an alpha of 1... The log statement 'In Here' is called so it seems to be executing the right code, but that code doesn't seem to be doing anything. Can anyone explain what I've done wrong? Thanks, Jack

  • How does one make the camera on the iphone appear from the app delegate? Is it possible?

    - by K-RAN
    I'm just playing around with a simple program that opens the camera. That's literally all that I want to do. I'm a beginner and I believe that I have the basics down in terms of UI management for the iPhone so I decided to give this one a whirl. What I'm trying to do right now is... - (BOOL) application:(UIApplication*) application didFinishLaunchingWithOptions:(NSDictionary*) launchOptions { UIImagePickerController * camera = [[UIImagePickerController alloc] init]; camera.delegate = self; camera.sourceType = UIImagePickerControllerSourceTypeCamera; camera.allowsEditing = NO; camera.showsCameraControls = NO; [viewController presentModalViewController:camera animated:NO]; [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES: } So basically, initialize the camera, set some things and show it in the main view. I set the camera's delegate to self because this code is placed in the delegate class (and yes, the delegate class is conforming to UIImagePickerControllerDelegate && UINavigationControllerDelegate). Main problem right now is that nothing is appearing on the screen. I have absolutely no idea what I'm doing wrong, especially since the program is building correctly with no errors or warnings... Any help is appreciated! Thanks a lot :D
