  • Unable to load UIView with initWithNibName in Apple SDK 3.1.3

    - by James Foster
    I am trying to load my UIViewController and corresponding UIView programmatically in the AppDelegate class. I have the following in the applicationDidFinishLaunchingMethod of the AppDelegate class: (void)applicationDidFinishLaunching:(UIApplication *)application { NSLog(@"--- AppDelegate applicationDidFinishLaunching Start"); // Override point for customization after application launch //MainController *controller = [[MainController alloc] initWithNibName:@"MainView" bundle:nil]; MainController2 *controller = [[MainController2 alloc] initWithNibName:@"MainView2" bundle:nil]; if (controller.view == nil) { NSLog(@"--- controller view is nil!!!!!!"); } [window addSubview:controller.view]; [window makeKeyAndVisible]; NSLog(@"--- AppDelegate applicationDidFinishLaunching End"); } Basically the view in the viewController doesn't load and when the application launches, it just shows the blank window. What is funny is that it worked before and then just stopped working. I am wondering if this is a bug in iPhone SDK 3.1.3??? This is a really annoying issue, and I was quite a ways along in a new project when I started having this problem and had to start over with a blank project and copy over all of my resources, when it started happening again... I have uninstalled iPhone OS 3.1.3 and reinstalled and the problem prevails... I also created a second UIViewController class and corresponding nib which DOES LOAD just fine... I am not sure why one works and the other doesn't it... You can download a sample project which demonstrates this issue at the following link: http://www.mediafire.com/?nmhnmhbeyki To switch back and forth between the working/nonworking UIViewController and UIView simply comment comment/comment out the initWithNibLine lines in the AppDelegate and the corresponding #import "MainController.h" statements in the appdelegate.h file... Any ideas??? The sample project I have linked to isolates the problem in as few files/lines of code as possible... I appreciate any help you might be able to provide. Thanks, James

  • Objective-C SSL Synchronous Connection

    - by Mike
    Hello, I'm a little new to objective-C but have run across a problem that I can't solve, mostly because I'm not sure I am implementing the solution correctly. I am trying to connect using a Synchronous Connection to a https site with a self-signed certificate. I am getting the Error Domain=NSURLErrorDomain Code=-1202 "untrusted server certificate" Error that I have seen some solutions to on this forum. The solution i found was to add: - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; } to the NSURLDelegate to accept all certificates. When I connect to the site using just a: NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://examplesite.com/"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; It works fine and I see the challenge being accepted. However when I try to connect using the synchronous connection I still get the error and I don't see the challenge functions being called when I put in logging. How can I get the synchronous connection to use the challenge methods? Is it something to do with the delegate:self part of the URLConnection? I also have logging for sending/receiving data within the NSURLDelegate that is called by my connection function but not by the synchronous function. What I am using for the synchronous part: NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:@"https://examplesite.com/"]]; [request setHTTPMethod: @"POST"]; [request setHTTPBody: [[NSString stringWithString:@"username=mike"] dataUsingEncoding: NSUTF8StringEncoding]]; dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSLog(@"%@", error); stringReply = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding]; NSLog(@"%@", stringReply); [stringReply release]; NSLog(@"Done"); Like I mentioned I'm a little new to objective C so be kind :) Thanks for any help.

  • UITableView UITableViewCell not reloading on reloadData

    - by David van Dugteren
    This question has been asked a few times now, but there exists no answer on the web that has solved the problem for me yet... See the code: { const NSInteger TOP_LABEL_TAG = 1001; static NSString *CellIdentifier = @"CellIdentifier"; UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } getAQuestionToAnswer = [[QuestionsToAnswer sharedInstance] getLatestLoadedQuestion]; UILabel *topLabel; topLabel = [[[UILabel alloc] initWithFrame: CGRectMake ( 50, 18, 260, 75)] autorelease]; [cell.contentView addSubview:topLabel]; topLabel.tag = TOP_LABEL_TAG; topLabel.backgroundColor = [UIColor clearColor]; topLabel.textColor = [UIColor colorWithRed:0.25 green:0.0 blue:0.0 alpha:1.0]; topLabel.highlightedTextColor = [UIColor colorWithRed:1.0 green:1.0 blue:0.9 alpha:1.0]; [topLabel setFont:[UIFont fontWithName:@"MarkerFelt-Thin" size:13]]; topLabel.numberOfLines = 4; topLabel = (UILabel *)[cell viewWithTag:TOP_LABEL_TAG]; topLabel.text = [NSString stringWithFormat:@"%@", [getAQuestionToAnswer valueForKey:@"question"] ]; Some code is omitted but the basics is there, I'm updating by means of a shake gesture, the NSLog confirms that the getAQuestionToAnswer is indeed updated with a new question after the gesture. Yet at run time, no matter what I do... e.g. [self.tableview reloaddata]; nothing works. It just doesn't want to refresh.

  • iPhone UIScrollview with UIButtons - how to recreate springboard?

    - by Patrick
    I'm trying to create a springboard-like interface within my app. I'm trying to use UIButtons added to a UIScrollView. The problem I'm running in to is with the buttons not passing any touches to the UIScrollView - if I try to flick/slide and happen to press on the button it doesn't register for the UIScrollView, but if I flick the space between buttons it will work. The buttons do click/work if I touch them. Is there a property or setting that forces the button to send the touch events up to its parent (superview)? Do the buttons need to be added to something else before being added the UIScrollView? Here is my code: //init scrolling area UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 480, 480)]; scrollView.contentSize = CGSizeMake(480, 1000); scrollView.bounces = NO; scrollView.delaysContentTouches = NO; //create background image UIImageView *rowsBackground = [[UIImageView alloc] initWithImage:[self scaleAndRotateImage:[UIImage imageNamed:@"mylongbackground.png"]]]; rowsBackground.userInteractionEnabled = YES; //create button UIButton *btn = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; btn.frame = CGRectMake(100, 850, 150, 150); btn.bounds = CGRectMake(0, 0, 150.0, 150.0); [btn setImage:[self scaleAndRotateImage:[UIImage imageNamed:@"basicbutton.png"]] forState:UIControlStateNormal]; [btn addTarget:self action:@selector(buttonClick) forControlEvents:UIControlEventTouchUpInside]; //add "stuff" to scrolling area [scrollView addSubview:rowsBackground]; [scrollView addSubview:btn]; //add scrolling area to cocos2d //this is just a UIWindow [[[Director sharedDirector] openGLView] addSubview:scrollView]; //mem-mgmt [rowsBackground release]; [btn release]; [scrollView release];

  • iPhone mapView / mapKit using removeAnnotation & addAnnotation results in memory leak?

    - by user266618
    To update the location of a GPS indicator on mapView... [mapView removeAnnotation:myGpsAnnotation]; [myGpsAnnotation release]; myGpsAnnotation = nil; myGpsAnnotation = [[MapLocationAnnotation alloc] initWithCoordinate:region.center annotationType:MapAnnotationTypeGps title:MAP_ANNOTATION_TYPE_GPS]; [mapView addAnnotation:myGpsAnnotation]; ...I see net memory slowly climbing in Instruments (simulator). No "Leak" blip, but "Net Bytes" and "# Net" slowly incrementing... unless this code is commented out. So I'm 100% certain this is the offending code. BUT if I do the following... [mapView removeAnnotation:myGpsAnnotation]; [myGpsAnnotation release]; myGpsAnnotation = nil; myGpsAnnotation = [[MapLocationAnnotation alloc] initWithCoordinate:region.center annotationType:MapAnnotationTypeGps title:MAP_ANNOTATION_TYPE_GPS]; [mapView addAnnotation:myGpsAnnotation]; [mapView removeAnnotation:myGpsAnnotation]; [mapView addAnnotation:myGpsAnnotation]; [mapView removeAnnotation:myGpsAnnotation]; [mapView addAnnotation:myGpsAnnotation]; ...then the "Net Bytes" and "# Net" increase much faster. Is it possible this isn't my mistake, and I'm trying to track down a leak in MapKit? Am I really leaking memory? Again, nothing appears under "Leaks", but then I don't see why Net values would be continually climbing. Thanks for any help, -Gord

  • Iphone xCode - Navigation Controller on second xib view?

    - by Frames84
    Everything is fine, my navigation controller display's my 'Menu 1' item, but when i click it there appears to be a problem with the: [self.navigationController pushViewController:c animated:YES]; line it doesn't connect to the break point in the myClass file. so I think i've not joined something? but unsure what? my second view with the navigation controller doesn't have direct access to the AppDelegate so can't join it like i see in some tutorials. 1st view is just a button when clicked calls: [self presentModalViewController:mainViewController animated:YES]; my second View 'MainViewController' header looks like: @interface MainViewController :UITableViewController <UITableViewDelegate, UITableViewDataSource> { NSArray *controllers; UINavigationController *navController; } @property (nonatomic, retain) IBOutlet UINavigationController *navControllers; @property (nonatomic, retain) NSArray *controller; Then I have my MainViewController.m @synthesize controllers; @synthesize navController; - (void) viewDidLoad { NSMutableArray *array = [[NSMutaleArray alloc] init]; myClass *c = [[myClass alloc] initWithStyle:UITableViewStylePlain]; c.Title = @"Menu 1"; [array addObject:c]; self.Controllers = array; [array release]; } implemented numberOfRowsInSection and cellForRowAtIndexPath - (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger row = [indexPath row]; myClass *c = [self.controllers objectAtIndex:row]; [self.navigationController pushViewController:c animated:YES]; // doesn't load myClass c // [self.navController pushViewController:c animated:YES]; } Also in interface designer I dragged a Navigation Controller onto my new XIB and changed the Root View Controller class to MainViewController and also connected the File Owner connector to the Navigation Controller to connect the navController Outlet. Thanks for you time.

  • How to change the border color of a Grouped UITableView

    - by ctpenrose
    This concerns iPhoneOS-sdk-3.2 I am having difficulty changing the border color of a grouped UITableView. I can change the cell background color, separator color, text color, quite easily now, and the rounded corners clip correctly, even when highlighted with whatever colors I have chosen. However the surrounding border remains infuriatingly gray despite many different attempts. I have read all of the related posts I can find via Google, let alone stackoverflow. I have tried both a programmatic and xib-based solution and both provide the same results. I will share the programmatic version below: I have a UIViewController subclass rather than a UITableViewController subclass to act as a UITableView delegate -- I chose this route as I am coding on the iPad and UITableViewController reportedly takes over the whole screen. loadView method of my UIViewController subclass: - (void) loadView { self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; [self.view release]; self.view.backgroundColor = [UIColor blackColor]; // add and configure UITableView CGRect tableViewRect = CGRectMake(0., 0., 256., 768.); myTableView = [[UITableView alloc] initWithFrame:tableViewRect style:UITableViewStyleGrouped]; // set the tableview delegate to this object and the datasource to the datasource which has already been set myTableView.delegate = self; myTableView.dataSource = self; myTableView.sectionIndexMinimumDisplayRowCount=1; myTableView.backgroundColor = [UIColor clearColor]; myTableView.separatorColor = [UIColor whiteColor]; myTableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine; myTableView.opaque = NO; // add the table view to our background view [self.view addSubview:myTableView]; [myTableView release]; }

  • Can you force a MPMoviePlayerPlaybackDidFinishNotification ?

    - by Jonathan
    Hi, I have several movies that are played and presented using this code. As you can see I also have removed the default movie controls and have added a custom overlay which essentially just stops the video. Here is my problem... When I stop the movie with my custom overlay button, I don't seem to be getting the 'MPMoviePlayerPlaybackDidFinishNotification' Note: everything works normal if I let the movie play through and it stop by itself. Is the any way of 'forcing' the PlaybackDidFinish notification? Can I do something like this [self moviePlayBackDidFinish:something]; ? Thank You! - (void) playMovie { NSString *path = [[NSBundle mainBundle] pathForResource:@"movie_frog" ofType:@"m4v"]; NSURL *url = [NSURL fileURLWithPath:path]; MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:url]; if(mp) { self.myMoviePlayer = mp; [mp release]; //movie view [self.view addSubview:myMoviePlayer.view]; myMoviePlayer.view.frame = CGRectMake(0.0,0.0,480,320); self.myMoviePlayer.controlStyle = MPMovieControlStyleNone; [self.myMoviePlayer play]; //videoNav _videoNav = [[videoNav alloc] initWithNibName:@"videoNav" bundle:nil]; [self.view addSubview:_videoNav.view]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; } }

  • UIBarButtonItem with custom image and no border

    - by mongeta
    Hello, I want to create a UIBarButtonItem with a custom image, but I don't want the border that iPhone adds, as my Image has a special border. It's the same as the back button but a forward button. This App is for an inHouse project, so I don't care if Apple reject or approves it or likes it :-) If I use the initWithCustomView:v property of the UIBarButtonItem, I can do it: UIImage *image = [UIImage imageNamed:@"right.png"]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; [button setBackgroundImage: [image stretchableImageWithLeftCapWidth:7.0 topCapHeight:0.0] forState:UIControlStateNormal]; [button setBackgroundImage: [[UIImage imageNamed: @"right_clicked.png"] stretchableImageWithLeftCapWidth:7.0 topCapHeight:0.0] forState:UIControlStateHighlighted]; button.frame= CGRectMake(0.0, 0.0, image.size.width, image.size.height); [button addTarget:self action:@selector(AcceptData) forControlEvents:UIControlEventTouchUpInside]; UIView *v=[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height) ]; [v addSubview:button]; UIBarButtonItem *forward = [[UIBarButtonItem alloc] initWithCustomView:v]; self.navigationItem.rightBarButtonItem= forward; [v release]; [image release]; This works, but if I have to repeat this process in 10 views, this is not DRY. I suppose I have to subclass, but what ? NSView ? UIBarButtonItem ? thanks, regards,

  • UIImagePickerController crashing

    - by Mike
    I am developing a project based on iPhone OS 3.2 This project uses UIImagePickerController to pick videos. I have managed to put a video inside the iPad simulator. Photos.app can see and play the video, that was created using an iPhone 3GS, but whey I try to use the UIImagePickerController, it simply crashes my app. THis is the code I am using: if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypePhotoLibrary]) { UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; picker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:picker.sourceType];//shows movies and photos on iPhone picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker]; CGRect myRect = CGRectMake(0,0,100,100); // this is a random rect just for testing [popover presentPopoverFromRect:myRect inView:myMainView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } after running this, the app crashes miserably with the following message Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Popovers cannot be presented from a view which does not have a window.' Is there something wrong with the code or it is just the simulator crashing because it is unable to pick videos? please refrain from recommending me to test on a real device. The problem is that I live outside the US and there's no iPad here soon. thanks.

  • UIActivityIndicatorView is not display at the right time

    - by Alexandre
    I'm making a form that allows the user to enter datas in my IOS application. This form allows the user to enter a lot of repetive datas. So, sometimes, the process takes time and I would like to display a UIActivityIndicatorView during this process. Unfortunalty the spinner appears only one second or less at the end of the process, not at the beginning as expected. There is some code : - (void) manageSpinner{ spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; [spinner setCenter:CGPointMake(self.view.bounds.size.width/2.0, self.view.bounds.size.height/2.0)]; // I do this becau I'm in landscape mode UIImageView *imageView = [[UIImageView alloc]initWithFrame:self.tableView.bounds]; UIImage *image = [UIImage imageNamed:@"dark_gradiant.jpg"]; [imageView setImage:image]; [imageView addSubview:spinner]; [self.tableView addSubview:imageView]; [spinner startAnimating]; } //On click save by the user - (IBAction)save:(id)sender{ //Collect information from the form myObject.name = nameTF.text; [...] if(informations OK[...]){ //Manage spinner [self manageSpinner]; //Add : this is the long process for (int i=0; i<nbRepeatChooseByUser; i++) { [myObject register]; } //Call the delegate that will dismiss the form [self.delegate theSaveButtonOnTheAddMyObjectTVCWasTapped:self]; } } The spinner is called before the adding method but it seems to be set up after the process. Thank you, Alexandre

  • little more help with a CATiledLayer

  • Update iPhone UIProgressView during NSURLConnection download.

    - by Scott Pendleton
    I am using this code: NSURLConnection *oConnection=[[NSURLConnection alloc] initWithRequest:oRequest delegate:self]; to download a file, and I want to update a progress bar on a subview that I load. For that, I use this code: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [oReceivedData appendData:data]; float n = oReceivedData.length; float d = self.iTotalSize; NSNumber *oNum = [NSNumber numberWithFloat:n/d]; self.oDPVC.oProgress.progress = [oNum floatValue]; } The subview is oDPVC, and the progress bar on it is oProgress. Setting the progress property does not update the control. From what I have read on the Web, lots of people want to do this and yet there is not a complete, reliable sample. Also, there is much contradictory advice. Some people think that you don't need a separate thread. Some say you need a background thread for the progress update. Some say no, do other things in the background and update the progress on the main thread. I've tried all the advice, and none of it works for me. One more thing, maybe this is a clue. I use this code to load the subview during applicationDidFinishLaunching: self.oDPVC = [[DownloadProgressViewController alloc] initWithNibName:@"DownloadProgressViewController" bundle:nil]; [window addSubview:self.oDPVC.view]; In the XIB file (which I have examined in both Interface Builder and in a text editor) the progress bar is 280 pixels wide. But when the view opens, it has somehow been adjusted to maybe half that width. Also, the background image of the view is default.png. Instead of appearing right on top of the default image, it is shoved up about 10 pixels, leaving a white bar across the bottom of the screen. Maybe that's a separate issue, maybe not.

  • TTStyledTextLabel offset between link and regular text when changing from default font

  • Blind down animation on CALayer using a mask

    - by dgjones346
    Hi there, I want to create a "blind down" effect on an image so the image "blinds down" and appears. Sort of like this JavaScript transition: http://wiki.github.com/madrobby/scriptaculous/effect-blinddown The mask is setup correctly because if I manually change it's position it hides and reveals the image behind it, but it doesn't animate! It just ends up in the animates final position and you never see it actual blind. Please help! Maybe this isn't the best way to achieve a blind down effect? // create a new layer CALayer *numberLayer = [[CALayer alloc] init]; // render the number "7" on the layer UIImage *image = [UIImage imageNamed:@"number-7.png"]; numberLayer.contents = (id) [image CGImage]; numberLayer.bounds = CGRectMake(0, 0, image.size.width, image.size.height); // width and height are 50 numberLayer.position = position; // create a new mask that is 50x50 the size of the image CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init]; CGMutablePathRef path = CGPathCreateMutable(); CGPathAddRect(path, nil, CGRectMake(0, 0, 50, 50)); [maskLayer setPath:path]; [maskLayer setFillColor:[[UIColor whiteColor] CGColor]]; [theLayer setMask:maskLayer]; [maskLayer setPosition:CGPointMake(0, 0)]; // place the mask over the image [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:3.0]; [maskLayer setPosition:CGPointMake(0, 50)]; // slide mask off the image // this should shift the blind away in an animation // but it doesn't animate [UIView commitAnimations]; [maskLayer release]; [boardLayer addSublayer:numberLayer]; [numberLayer release];

  • UIActionSheet positioning problem

    - by Dave
    I need to display a pop with a UISwitch and a Done button when user taps on a button and save the state of the switch when the done button in the pop up is tapped. So I use UIActionSheet to do this - sheet = [[UIActionSheet alloc] initWithTitle:@"Switch Setting" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Done", nil]; theSwitch = [[UISwitch alloc] init]; [sheet addSubview:theSwitch]; [sheet showInView:self.view]; - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.firstOtherButtonIndex) { theSwitch .on? NSLog(@"Switch is on") : NSLog(@"Switch if off"); } } All this works great. I have problem with positioning. Unfortunately, I don't have a screen shot at the moment to post here. But the switch appears at the very top on the same line with the Action Sheet title and then below that is the Done button. Please someone help me how to position the switch below the Title and increase the Action Sheet size so it looks neat. I need this asap. Thanks.

  • Using UIScreen to drive a VGA display - doesn't seem to show the UIWindow?

    - by Peter Hajas
    HI there, I'm trying to use UIScreen to drive a separate screen with the VGA dongle on my iPad. Here's what I've got in my root view controller's viewDidLoad: //Code to detect if an external display is connected to the iPad. NSLog(@"Number of screens: %d", [[UIScreen screens]count]); //Now, if there's an external screen, we need to find its modes, itereate through them and find the highest one. Once we have that mode, break out, and set the UIWindow. if([[UIScreen screens]count] > 1) //if there are more than 1 screens connected to the device { CGSize max; UIScreenMode *maxScreenMode; for(int i = 0; i < [[[[UIScreen screens] objectAtIndex:1] availableModes]count]; i++) { UIScreenMode *current = [[[[UIScreen screens]objectAtIndex:1]availableModes]objectAtIndex:i]; if(current.size.width > max.width); { max = current.size; maxScreenMode = current; } } //Now we have the highest mode. Turn the external display to use that mode. UIScreen *external = [[UIScreen screens] objectAtIndex:1]; external.currentMode = maxScreenMode; //Boom! Now the external display is set to the proper mode. We need to now set the screen of a new UIWindow to the external screen external_disp = [externalDisplay alloc]; external_disp.drawImage = drawViewController.drawImage; UIWindow *newwindow = [UIWindow alloc]; [newwindow addSubview:external_disp.view]; newwindow.screen = external; }

  • How to create a UIScrollView Programmatically?

    - by Wayfarer
    Alright, so the key here is I'm not using IB at all, because the View I'm working with is created programmatically. The UIView covers the lower half the screen, and has a bunch of buttons on it. However, I want to add more buttons to the UIView, without making it any larger. To do so, I want to make a UIScrollView inside the view, which will allow me to add more buttons off screen so the user can scroll to them. I think that's how it works. self.manaView = [[[UIView alloc] initWithFrame:frame] autorelease]; self.manaView.backgroundColor = [UIColor purpleColor]; UIScrollView *scroll = [UIScrollView alloc]; scroll.contentSize = CGSizeMake(320, 400); scroll.showsHorizontalScrollIndicator = YES; [self.manaView addSubview:scroll]; The first part of the code iniates my UIView, which works great, but I can't figure out how to make the UIScrollView programmatically and add it to the view, and then add the buttons to it. UIButton *ret2 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; ret2.tag = 102; ret2.frame = CGRectMake(255, 5, 60, 50); [ret2 setTitle:@"Return" forState:UIControlStateNormal]; [ret2 addTarget:self action:@selector(flipAction:) forControlEvents:UIControlEventTouchUpInside]; [scroll addSubview:ret2]; When I did that, the button simply disappeared off my screen. So How do I do this correctly? Thank you for your help!

  • UINavigationController with UIView and UITableView

    - by Tobster
    I'm creating a navigation-based app which displays a graph, rendered with openGL, and a tableview listing disclosure buttons of all of the elements that are displayed on the graph, and a settings disclosure button. The navigation controller is also a tableview delegate and datasource, and the tableview is added to the view programatically and has its' delegate and datasource set to 'self'. The OpenGL based graph view is added via IB. The problem I'm having is that I'm trying to push a view controller (either settings or graph element properties) within the didSelectRowAtIndexPath method. The method registers and the new view is pushed on, but the tableview stays and obscures part of the view that was pushed on, as if it has a different navigation controller. I can't seem to set the tableview's navigation controller to be the same as the rest of the UINavigationControllers' view. Does anyone know how I could fix this? My navigation controllers' initWithCoder method, where the tableview is added, appears as follows: elementList = [[UITableView alloc] initWithFrame:tableFrame style:UITableViewStyleGrouped]; elementList.dataSource = self; elementList.delegate = self; [self.view addSubview:elementList]; Further in the source file, the DidSelectRowAtIndexPath method where the navigation controller is pushed appears as follows: Settings* Controller = [[Settings alloc] init]; [self pushViewController:Controller animated:YES]; [Controller release];

  • Apple Push Notification-Unable to callback didRegisterForRemoteNotificationsWithDeviceToken

    - by Shailesh Kanzariya
    I have been simply trying to get deviceToken from my iPhone application using Apple Push Notification Service. I don't have any implementation on server side for the time being. I have created APP Id, got SSL certificate, Provision Profile with APN and calling - (void)applicationDidFinishLaunching:(UIApplication *)application { //view init and add sub view to window [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound]; } method. When I execute the application it pop ups action box to allow Push Notification (means my request for APN registration is working) but my callback is not executed. Neither didRegisterForRemoteNotificationsWithDeviceToken nor didFailToRegisterForRemoteNotificationsWithError is called? can anybody help me to resolve the issue? Following are my callbacs for reference. - (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"APNClient" message:@"Entered into Error Method" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; NSLog(@"Error in registration. Error: %@", err); } - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"APNClient" message:@"Got the deviceToken..!" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; }

  • UITextField in UIAlertView doesn't respond to cut/copy/paste on second showing

    - by Jesse Grosjean
    I"m adding a UITextView to a UIAlertView with the following code: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Name Here" message:@"this gets covered!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK!", nil]; UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)]; CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60); [alert setTransform:myTransform]; [myTextField setBackgroundColor:[UIColor whiteColor]]; [alert addSubview:myTextField]; [alert show]; [alert release]; [myTextField release]; If I place that code in a standard action method: - (IBAction)testAlertView:(id)sender { ...the above code... } Then the first time I show the alert view the cut/copy/paste popup menu will show in the text fields that's been added to the alert view. (For instance if I tap and hold, then "Paste" will popup after I release. The problem is after working correctly the first time, none of the cut/copy/paste buttons will show up again when I show the alert view unless I restart the app. Does anyone know why, or how to fix this problem? Bonus information I just found out that I can get things to always work if I create an show the alert within a UIActionSheet delagate callback. For instance this always works (cut/copy/paste always shows up when in the UITextField when appropriate) - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { ...the above code... } Any idea what might be happening in this second case that make things work? I don't want to use a UIActionSheet in my app, so I'd like to find a way to make it work from a plain old action method. Thanks, Jesse

    Edit Reposting... I accidentally marked my previous question as "commuity wiki" and didn't realize that answers to wiki posts don't generate reputation.

  • issues make a persistent object in Objective C

    - by oden
    Attempting to make a NSObject called 'Person' that will hold the login details for my application (nothing to fancy). The app is made of a navigation controller with multiple table views but I am having issues sharing the Person object around. Attempted to create a static object like this: + (Person *)sharedInstance { static Person *sharedInstance; @synchronized(self) { if(!sharedInstance) sharedInstance = [[Person alloc] init]; return sharedInstance; } return nil; } And here is the header // Person.h #import <Foundation/Foundation.h> @interface Person : NSObject { NSString *fullName; NSString *firstName; NSString *lastName; NSString *mobileNumber; NSString *userPassword; } @property(nonatomic, retain) NSString *fullName; @property(nonatomic, retain) NSString *firstName; @property(nonatomic, retain) NSString *lastName; @property(nonatomic, retain) NSString *mobileNumber; @property(nonatomic, retain) NSString *userPassword; + (Person *)sharedInstance; -(BOOL) setName:(NSString*) fname; -(BOOL) setMob:(NSString*) mnum; -(BOOL) setPass:(NSString*) pwd; @end This object setters and getters are needed in different parts of the application. I have been attempting to access them like this Person * ThePerson = [[Person alloc] init]; ThePerson = nil; NSString * PersonsName; PersonsName = [[Person sharedInstance] firstName]; Everything works well at the login screen but it dies at the next use. usually EXC_BAD_ACCESS (eek!). Clearly I am doing something very wrong here. Is there an easier way to share objects between different a number view controllers (both coded and xib)?
