  • Creating Actions from UIActionSheets help

    - by user337174
    I am using two UIAction sheets within my current project. I can get one to work perfectly fine but when i insert a second action sheet it runs the same arguements as the first. How do i define the actionsheets seperatly? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [actionSheet release]; } -(IBAction) mapButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *mapActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Map"],nil]; mapActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [mapActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [mapActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } }

  • http authenitcation in xcode

    - by user313100
    I am trying to make twitter work in my app and everything works fine except the code does not seem to recognize an error from twitter. If the username/password are not valid, I get an error message through this function: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSString* strData = [[[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding:NSASCIIStringEncoding] autorelease]; NSLog(@"Received data: %@", strData ) ; return ; } It prints: Received data: Could not authenticate you. . However, the app continues to the post a tweet view I have and ignores the error. Obviously, I do not have something setup right to detect such an error from twitter so my question is how do I get xcode to recognize an error like this? This uses basic http auth btw and don't mention anything about OAuth...just trying to get this to work for now.

  • 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? Thanks a bunch for the help...

  • Download data in background with iOS4

    - by Sagar
    As per the latest update of Kindle V2.5, it has support of "continue downloading books while the app is in the background on iOS 4 devices". How is it possible to download content in background? As per the iOS multitasking documentation, only audio, voip & location updates are possible in background. And I've also maken sure that NSURLConnection doesn't download new data work while app goes background. Then how's it possible with Kindle app? Edit: I haven't checked Kindle App in iOS4 multitasking enabled device. So if anyone let me (& community) know what exactly Kindle app does to download, that would be very much helpful.

  • UIActivityIndicator not working properly?

    - by medma
    Hello frends, I have a problem regarding UIActivityIndicator. I applied "[spinner startAnimating]" at the IBAction on a button and then doing some process. After the process activityindicator should be stopped and then navigate to another view. But the activity indicator does not appear. When I remove the line "[spinner stopAnimating]" then the indicator appears but not at the instant button is pressed. It appears just before the other view loads, and apparently does not appear, I mean it does not appear but if we see very carefully then only it appears for an instant. Thanx in advance for any answer.

  • GKSession sendDataToAllPeers including sendee?

    - by Typeoneerror
    I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. Should call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would just sendData and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendData list so that it responds exactly the same as all connected peers?

  • reloadData not working - suspect cell's reuseIdentifier

    - by retailevolved
    I have a view controller that gets presented modally and changes some data that effects the data in a uitableview in the modal's parent view controller (a table view). I call the tableview's reloadData method when the parent view reappears. I have confirmed that this code gets hit with a break point. My trouble is, reloadData isn't working. Here's the kicker - if I don't use reuseIdentifiers in the - (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath method, the data reloads correctly. It looks like the reuseIdentifier is to blame. I really want to continue to use the reuseIdentifier for my cells - how do I make this work?

  • How to add an extra plist property using CMake?

    - by Jesse Beder
    I'm trying to add the item <key>UIStatusBarHidden</key><true/> to my plist that's auto-generated by CMake. For certain keys, it appears there are pre-defined ways to add an item; for example: set(MACOSX_BUNDLE_ICON_FILE ${ICON}) But I can't find a way to add an arbitrary property. I tried using the MACOSX_BUNDLE_INFO_PLIST target property as follows: I'd like the resulting plist to be identical to the old one, except with the new property I want, so I just copied the auto-generated plist and set that as my template. But the plist uses some Xcode variables, which also look like ${foo}, and CMake grumbles about this: Syntax error in cmake code when parsing string <string>com.bedaire.${PRODUCT_NAME:identifier}</string> syntax error, unexpected cal_SYMBOL, expecting } (47) Policy CMP0010 is not set: Bad variable reference syntax is an error. Run "cmake --help-policy CMP0010" for policy details. Use the cmake_policy command to set the policy and suppress this warning. This warning is for project developers. Use -Wno-dev to suppress it. In any case, I'm not even sure that this is the right thing to do. I can't find a good example or any good documentation about this. Ideally, I'd just let CMake generate everything as before, and just add a single extra line. What can I do?

  • How to manage a single-selection (exclusive) list?

    - by Andy
    I've got a detail view that consists of a table view with a few rows of data. I can fill the rows just fine, and moving back and forth from the parent view to the subview works too. This detail view should allow the user to select a single value, placing a checkmark accessory in the cell and then returning to the parent view (where the selected value becomes the cell.textLabel.text property of the cell from which the detail view was called). This all works as of right now. However, when the user taps the cell in the parent view to go back to the detail view (to change their selection), my checkmark has disappeared and I cannot for the life of me figure out how to make it stay. Here's my cellForRowAtIndexPath: method: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; } NSString *labelText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumberLabel"]; cell.textLabel.text = labelText; NSString *currentLabel = [ruleBuilder.tableView cellForRowAtIndexPath:selectedIndexPath].textLabel.text; if (labelText == currentLabel) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } NSString *detailText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumber"]; cell.detailTextLabel.text = detailText; return cell; } I've checked out Apple's sample code for exclusive-list management in Table View Programming Guide, but the snippet seems incomplete, and I can't find the related code in Apple's sample code. This doesn't seem like it ought to be that hard to do.

  • How to mask an view with an black-white image?

    - by mystify
    I've heard that it's possible to mask views with black/white images, where black means fully transparent and white means view is visible. The big difference to clipsToBounds is that the view could be clipped in funny shapes like circles or stars. How could I do that?

  • Can't add to NSMutableArray from SecondaryView

    - by Antonio
    Hi guys, I've searched and read and still haven't found a concrete answer. Brief: I have an application where I declare an NSMutableArray in my AppDelegate to synthesize when the application loads. (code below). I have a SecondaryViewController call this function, and I have it output a string to let me know what the array size is. Every time I run it, it executes but it does not add any objects to the array. How do I fix this? AppDelegate.h file #import <UIKit/UIKit.h> @class arrayTestViewController; @interface arrayTestAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; arrayTestViewController *viewController; NSMutableArray *myArray3; } @property (nonatomic, retain) NSMutableArray *myArray3; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet arrayTestViewController *viewController; -(void)addToArray3; @end AppDelegate.m file #import "arrayTestAppDelegate.h" #import "arrayTestViewController.h" @implementation arrayTestAppDelegate @synthesize window; @synthesize viewController; @synthesize myArray3; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { myArray3 = [[NSMutableArray alloc] init]; // Override point for customization after application launch. // Add the view controller's view to the window and display. [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES; } -(void)addToArray3{ NSLog(@"Array Count: %d", [myArray3 count]); [myArray3 addObject:@"Test"]; NSLog(@"Array triggered from SecondViewController"); NSLog(@"Array Count: %d", [myArray3 count]); } SecondViewController.m file #import "SecondViewController.h" #import "arrayTestAppDelegate.h" @implementation SecondViewController -(IBAction)addToArray{ arrayTestAppDelegate *object = [[arrayTestAppDelegate alloc] init]; [object addToArray3]; }

  • How to push text from one UITextfield to another UITextfield in the next View? And back!?

    - by Chrizzz
    an Hi, I have an UITextField in one view, UITextField A in View A. And I have another in view B, UITextField B in View B. I use a Navigation Controller Bar to switch between the views. The UITextFields are properties and connected Outlets of both views A and B. On my view A there is an "Options"-button which pushes view B. So when you are typing in Textfield A, I would like the same text to appear in Textfield B. When you edit TextField B and you go back to view A (via the "Title View A"-button in de navigation bar), I would like the same text to re-appear in Textfield A. I expected this to be easy. But I can't get it working. I tried: ViewBController *controller = [[ViewBController alloc] initWithNibName:@"ViewBController" bundle:nil]; controller.TextFieldA.text = TextFieldB.text But nothing appeared in view B. And how do I get back? I dont want to use NSUserdefaults because I would have to remove the values also.

My code as follow, -(void)splashAnimation{ window = [[UIWindow alloc] initWithFrame:CGRectMake(0, 0, 320, 420)]; //scrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; scrollView = [[UIScrollView alloc] initWithFrame:[window bounds]]; scrollView.pagingEnabled = NO; scrollView.bounces = NO; UIImage *image = [UIImage imageNamed:@"splash.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; imageView.userInteractionEnabled = NO; [scrollView addSubview:imageView]; [scrollView setDelegate:self]; //[scrollView release]; /* window = [[UIWindow alloc] initWithFrame:CGRectMake(0, 0, 320, 420)]; UIView *splashView = [[UIView alloc] initWithFrame:[window bounds]]; UIImage *image = [UIImage imageNamed:@"splash.png"]; [splashView addSubview: [[UIImageView alloc] initWithImage:image]]; [window addSubview:splashView]; [window makeKeyAndVisible]; [window removeFromSuperview]; } - (void)applicationDidFinishLaunching:(UIApplication *)application { [self splashAnimation]; [self initControllers]; [window addSubview:[mainTabBarController view]]; [window makeKeyAndVisible]; } On my given code the one blank window comes up and stay on.

  • UIScrollView eating touches from its parent

    - by Jon Hull
    I have nested scrollViews (or rather a subclass of UIScrollView inside of an actual scrollview). I set the size of the inner view to its contentSize and set scrollEnabled = NO, because I only want the outside view scrolling. But the innerView occasionally eats touches and keeps the outerView from scrolling when it should. Is there something else I need to set to keep it from stealing the scrolling touches, but still allowing user interaction (e.g. editing a textView)?

  • Loading UINavigationController subclass from a Nib

    - by Rits
    My situation is as follows: My class SettingsViewController is a subclass of UINavigationController. That class contains the logic of its rootViewController. For example, it acts as the delegate and data source for two table views in that root view controller. I have no problem setting this up programmatically. In the initializer of SettingsViewController, I can create an additional UIViewController to serve as the root view controller, position the table views in its view, and set their delegates and data sources to self. But I want to load that root view via a Nib. The problem is, I do not know how to connect that Nib with my SettingsViewController, how to set the delegates and data sources. The SettingsViewController is not accessible from within the Nib. 'File Owner' represents the root view controller, not the SettingsViewController. How do I access my UINavigationController subclass from within my root view controllers Nib? Thanks in advance.

  • How can I remove the present view when I have added more than one subView ?

    - by srikanth rongali
    How can I remove the present view when I touched the close button. I did [self.view removeFromSuperView] when I added only one subView. It worked. But, I have now added another subView to the previous subView. I need to to get the parent view . How can I do it. My code of adding the subView is here. When I did the following only one view is removed. //FirstViewController: UIViewController -(void)libraryFunction:(id)sender { LibraryController *libraryController = [[LibraryController alloc]init]; [self.view addSubview:libraryController.view]; } //LibraryController: UIViewController -(void)viewDidLoad{ RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; self.navController = aNavigationController; [aNavigationController release]; [rootViewController release]; [self.view addSubview:navController.view]; } //RootViewController: UITableViewController - (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; } -(void)close:(id)sender { [self.view removeFromSuperview]; } Thank You.

  • CoreData could not fulfill a fault when adding new attribute

    - by cagreen
    I am receiving a "CoreData could not fulfill a fault for ..." error message when trying to access a new attribute in a new data model. If I work with new data I'm ok, but when I attempt to read existing data I get the error. Do I need to handle the entity differently myself if the attribute isn't in my original data? I was under the impression that Core Data could handle this for me. My new attribute is marked as optional with a default value. I have created a new .xcdatamodel (and set it to be the current version) and updated my NSPersistentStoreCoordinator initialization to take advantage of the lightweight migration as follows: NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; NSError *error = nil; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } Any help is appreciated.

  • What should be proper location for sqlit3 database file?

    - by Elliot Chen
    Hi, Everyone: I'm using a sqlite3 database to store app's data. Instead of building a database within program, I introduced an existing db file: 'abc.sqlite' into my project and put it under my 'Resources' folder. So, I think this db file should be inside of 'bundle', so at my init function, I used following statement to read it out: NSString *path = [[NSBundle mainBundle] pathForResource:@"abc" ofType:"sqlite"]; if(sqlite3_open([path UTF8String], &database) != SQLITE_OK) ... It's ok that this db can be opened and data can be retrieved from it. BUT, someone told me that it's better to copy this db file into user folder: such as 'Document'. So, my question is: is it ok to use this db from main bundle directly or copy it to user folder then use that copy. Which is better? Thank you very much!

  • Using NSUserDefaults to load data depending on which table view cell is pressed

    - by Bad_APPZ
    I want my app to work just like the 'contacts' app on iOS. When a user selects a certain TableViewCell, i want to load certain data. No Matter which cell is pressed, Either "Joseph, Richard, or Shannon", This view comes up: Both of the views look the exact same, but they just display different information. So i guess my question is: How can I programmatically set a key @"cell1" @"cell2", etc... for each cell using NSUserDefaults? But here is the catch, I dont know how many cells will be added, so i cant hard code this, How can I create a key for each table view cell for how ever many is added? Thanks for the help!

  • What to learn for a pure practical developer to get better?

    - by ChrisRamakers
    I'm a self taught developer that currently has more than enough experience to hold up against my colleagues waving with their degrees, yet I feel that I'm lacking some important skills to advance further into being a senior level professional in a leading role. More specific in the engineering, planning and designing aspect of software. I've touched the surface of UML, ERM/ERD, have experienced both waterfall and scrum projectmanagement, ... yet I feel there is something missing as every time I start on a new project I don't know where to begin. Should I start diagramming and how? should I start writing an xx page document describing the project on a technical level first, should I dive head first into writing the first tests and code or pseudo-code? I would like to know what, in my case, would be the best way forward, to learn how I can tackle this problem in the future and get better at leading and starting a project. There is not much i don't know about my technical tools and languages but when it gets abstract i'm in trouble.
