  • UILabel applying CGAffineTransformMakeRotation causing mysterious crash

    - by quantumpotato
    In -(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil parentController:(GameViewController *)myGameController{ Have a series of transforming labels like so: deg90 = 1.570796326794897; //....transforms background.center = CGPointMake(160,230); background.transform = CGAffineTransformMakeRotation(deg90); BetLabel.text = @"test"; BetLabel.transform = CGAffineTransformMakeRotation(deg90); That last line is crashing me with: 2010-04-13 21:04:47.858 Game[1204:207] * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (1) beyond bounds (1)' 2010-04-13 21:04:47.893 Game[1204:207] Stack: ( 864992541, 859229716, (lots of numbers) But if I comment it out, I get the text changing fine. Uh oh, just did a test.. turns out the other transforms were on UIImageViews. Apparently rotating a label in this xib is causing the crash. But in another file the transforms are working fine: newprofileentry.transform = CGAffineTransformMakeRotation(1.570796326794897); playerb0.transform = CGAffineTransformMakeRotation(1.570796326794897); playerb1.transform = CGAffineTransformMakeRotation(1.570796326794897); Tried substituting deg90 with the full float value, still the same crash. Tried cleaning cache, restarting IB and Xcode, cleaning all targets. Program has been running fine until I just added these labels. Tried deleting the label, readding and reconnecting the Outlet, too. Thanks for reading, hope someone has an idea about this. Cheers!

  • Appstore approval - Using activation codes.

    - by Tejaswi Yerukalapudi
    Hi, I'm in the process of building an app related to healthcare IT. My company wants to be able to distribute it through the appstore, but only if a device identified by the UDID of is specifically provisioned in the database. I've got all that built, but I was wondering if Apple might reject something like this. Has anyone had any experience with activation codes? Thanks, Teja.

  • Passing Variables between views / view controllers

    - by Dan
    Hi I'm new to ObjectiveC / IPhoneSDK and I'm informally trying to study it on my own. What I'm basically trying to do is from one view there are 12 zodiac signs. When a user clicks one, it proceeds to the second view (with animation) and loads the name of the zodiac sign it clicked in a UILabel, that's it. Here are my codes: Lovescopes = 1st page Horoscopes = 2nd page Lovescopes4AppDelegate.h #import <UIKit/UIKit.h> #import "HoroscopesViewController.h" #import "Lovescopes4AppDelegate.h" @class Lovescopes4ViewController; @interface Lovescopes4AppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; Lovescopes4ViewController *viewController; HoroscopesViewController *horoscopesViewController; } -(void)loadHoroscope; -(void)loadMainPage; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet Lovescopes4ViewController *viewController; @property (nonatomic, retain) HoroscopesViewController *horoscopesViewController; @end Lovescopes4AppDelegate.m #import "Lovescopes4AppDelegate.h" #import "Lovescopes4ViewController.h" @implementation Lovescopes4AppDelegate @synthesize window; @synthesize viewController; @synthesize horoscopesViewController; -(void)loadHoroscope { HoroscopesViewController *aHoroscopeViewController = [[HoroscopesViewController alloc] initWithNibName:@"HoroscopesViewController" bundle:nil]; [self setHoroscopesViewController:aHoroscopeViewController]; [aHoroscopeViewController release]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:window cache:YES]; [viewController.view removeFromSuperview]; [self.window addSubview:[horoscopesViewController view]]; [UIView commitAnimations]; } -(void)loadMainPage { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:window cache:NO]; [horoscopesViewController.view removeFromSuperview]; [self.window addSubview:[viewController view]]; [UIView commitAnimations]; [horoscopesViewController release]; horoscopesViewController = nil; } - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end Lovescopes4ViewController.h #import <UIKit/UIKit.h> #import "HoroscopesViewController.h" @interface Lovescopes4ViewController : UIViewController { HoroscopesViewController *hvc; } -(IBAction)loadAries; @property (nonatomic, retain) HoroscopesViewController *hvc; @end Lovescope4ViewController.m #import "Lovescopes4ViewController.h" #import "Lovescopes4AppDelegate.h" @implementation Lovescopes4ViewController @synthesize hvc; -(IBAction)loadAries { NSString *selected =@"Aries"; [hvc loadZodiac:selected]; Lovescopes4AppDelegate *mainDelegate = (Lovescopes4AppDelegate *) [[UIApplication sharedApplication] delegate]; [mainDelegate loadHoroscope]; } HoroscopesViewController.h #import <UIKit/UIKit.h> @interface HoroscopesViewController : UIViewController { IBOutlet UILabel *zodiacLabel; } -(void)loadZodiac:(id)zodiacSign; -(IBAction)back; @property (nonatomic, retain) IBOutlet UILabel *zodiacLabel; @end HoroscopesViewController.m #import "HoroscopesViewController.h" #import "Lovescopes4AppDelegate.h" @implementation HoroscopesViewController @synthesize zodiacLabel; /* // The designated initializer.

  • Hiding UIToolBar for child views of UITableViewController

    - by Robin Jamieson
    My main controller is a subclass of UITableViewController with a UIToolBar at the bottom and when a row is selected, I'd like to display another view without the toolbar. How can I hide the UIToolBar in the child view? Right now, it's present throughout all child views unless they're created as modal. Toolbar is created in RootController: self.toolbar = [[UIToolbar alloc] init]; // add tool bar items here [self.navigationController.view addSubview:toolbar]; RootController displays its child views as such: UIViewController *controller = [[UIViewController alloc] init...] [self.navigationController pushViewController:controller animated:YES]; RootController is instantiated as such in the app delegate's applicationDidFinishLaunching: RootController *rootcontroller = [[RootController alloc] initWithStyle:UITableViewStyleGrouped]; self.navigationController = [[UINavigationController alloc] initWithRootViewController:rootcontroller]; [rootcontroller release]; [window addSubview:[self.navigationController view]]; If I add the toolbar to [self.view] within RootController instead of navigationController's view, the toolbar disappears alltogether..

  • Design view disappeared from Interface Builder

    - by skywalker168
    All of a sudden, the visual design window disappeared from my Interface Builder. It is a regular UIView, has some UIImageView, UILabel, and UIButtons on it. When I open IB, I can see the document window (with File's Owner, First Responder and View in it), Library and Inspector, but the visual design window disappeared. Double click on "View" in the document window doesn't do anything. If I go to List mode, I can see all the components on the view, but just can no longer find the visual design window. All other XIB can open just fine, only this XIB lost its design window. First I thought maybe it was hidden somewhere on the screen. Tried all kinds of things, even rebooting the computer, but nothing helped. Can anyone help? Thanks in advance! By the way, I'm running SDK 3.2 Beta 3.

  • How to Unload a popped view controller?

    - by RexOnRoids
    Using a navigation based view hierarchy. I have a root view controller, and multiple view controllers that branch out from the same when a button is pressed. When a user presses the back button on the UINavigationBar, the current viewcontroller is popped and the display animates back to the rootviewcontroller. The problem is, I want the viewcontrollers to UNLOAD whenever they are popped. Seems like they are not unloading because when I go back to them they are still in the state they were when they were popped. How do I unload the viewcontrollers after navigating back to the rootviewcontroller?

  • how a view controller know when it is dismissed or poped out of the navigation controller stack?

    - by Thanh-Cong Vo
    Hi all, My view controller needs to know when it is poped out of the navigation controller stack, so that it can retain itself, wait and release itself later with another notification. I intend to do like that when the view is sent dealloc message: - (void)dealloc { if (self.isPerformingSomeTask) { self.isPopedOut = YES; [self retain]; return; } [super dealloc]; } But I think this is not a good solution? Any idea?

  • UIView Controller mysteriously getting deallocated

    - by Dan Ray
    I have a UINavigation scheme with a "welcome" page, a middle page, and a detail page. In the middle page, there's a segmented controller that can swap the main body of that page between a table, a calendar, and a MKMapView, each implemented with their own view controller classes. Today I implemented the MapView and its annotations and all of that. It's nice. And a detail disclosure on each callout takes you to the detail page just the same way as if you'd gotten there via the table. Lovely. I also have a right-button-bar button that pushes in a "search" view. From there you can search the data I'm navigating. When it's done filtering the data (an array of objects I'm keeping in a data singleton), it makes the table reload its data, and calls my annotation-clearer-and-builder methods on the map view, and then pops itself out, so the "middle" page (including whatever view was in the guts of it) is back on the screen. Problem is, if I go back and forth between the map and the search a couple times, any mention of the table view causes us to crash with: *** -[CALayer retain]: message sent to deallocated instance 0x710b810. (I obviously have NSZombies turned on.) I put an NSLog in the dealloc method of my table view controller. That thing's never getting called. I don't know if we're ditching it behind the scenes for memory purposes, or if I'm leaking it and can't get my hands back on it, or what. I'm sort of at a loss about where to look. Any hints?

  • I need to load a video stored in Applications folder in to a UITableView ?

    - by srikanth rongali
    I need to load a video stored in Applications folder in to a table view. When I touched the cell the video plays. I used the following code to get all the video files in to an array. NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray* contents = [fileManager directoryContentsAtPath:@"/Users/srikanth/Desktop/Projects/UF/Table2/Videos"]; for(a = 1; a < [contents count]; a++) NSLog(@"Array contents: %@", [contents objectAtIndex:a]); cells = [[NSMutableArray alloc]initWithCapacity:[contents count]]; But how can I load the videos into UITableView. I used NSBundle for loading videos by giving path. It worked. But, now I need the videos to load from the array contents. When I touch the cell of the table the corresponding file from the array contents si to be loaded. How can I make it? Thank you.

  • ASIHTTPRequest - HTTPS

    - by Tejaswi Yerukalapudi
    Does ASIHTTPRequest support HTTPS connections? My connection right now works for a HTTP connection and errors if I try a HTTPS Connection. (Goes into requestFailed and gives me a ASIHTTPErrorRequestDomain) -(void) getPatientsList { av.hidden = NO; [av startAnimating]; NSString *urlString = [IP stringByAppendingString:@"Method1"]; NSURL *url = [NSURL URLWithString:urlString]; ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; NSLog(@"URL = %@",url); [request setRequestMethod:@"POST"]; [request setPostValue:@"val1" forKey:@"key1"]; [request setPostValue:@"val2" forKey:@"key2"]; [request setDelegate:self]; [request startAsynchronous]; } - (void)requestFinished:(ASIHTTPRequest *)request { // Use when fetching text data //NSString *responseString = [request responseString]; // Use when fetching binary data NSData *responseData = [request responseData]; [self parsePatients:responseData]; [av stopAnimating]; av.hidden = YES; } - (void)requestFailed:(ASIHTTPRequest *)request { NSError *error = [request error]; [av stopAnimating]; av.hidden = YES; } Thanks, Teja

  • Detecting taps on a UIWebView

    - by dubbeat
    Hi, I'm trying to find a way to detect a double tap on a UIWebview. I want to use this action to close it. I however can't find and methods in the documentation for UIWebview taps. Whats the best to add taps to a uiwebview? I tried a tutorial here http://mithin.in/2009/08/26/detecting-taps-and-events-on-uiwebview-the-right-way/ But I don't know how to change my UIWindow to a tap detecting window. Does the above link seem like the best approach or could you suggest another way to remove my WebView?

  • Why I add the CGPoint in the NSMultable Array?

    - by Tattat
    I want to store my CGPoint to the NSMultable Array, so , I have method like this: [self.points addObject:CGPointMake(x, y)]; But I got the error, it said that : Incompatible type for argument 1 of "addObject". So, I check out the API, (void)addObject:(id)anObject anObject The object to add to the end of the receiver's content. This value must not be nil. So, I think the "CGPointMake" can make a Object, but it can't be assigned. What happens?

  • Why isn't UIScrollView always calling viewDidLoad on subviews?

    - by Rob S.
    I'm a bit confused on the behaviour of UIScrollView as it pertains to subview loading. In my app, I lazily load subviews into my scroller. Most of the time, -viewDidLoad is called on the subview immediately after adding it the UIScrollView. There is one scenario where it isn't being called. At the 'end' of my scroll view I have a "please wait" view. When it is fully scrolled on to the page, it fades out, I add the subview and -viewDidLoad is not called. In this case, when I remove the last subview and add another subview, I get nothing. I've tried [scrollView setNeedsDisplay] and [scrollView setNeedsLayout] to no avail. I've also sent the same messages to the view I just added - no dice. Does anyone have any insight here? Many people have many questions about -viewDidLoad and I haven't been able to find one related to direct subviews inside of a scrollview. Or I have and I haven't realized it :) Thanks in advance! Rob

  • XCode 3.2 does not mark unit test assert failures in the editor

    - by Cliff
    I've been off in Java land for about a month or so and now, upon returning to XCode I feel lost. I've upgraded 1st to 3.1.2 then recently to 3.2 and also got a new Mac with Snow Leopard so I'm not exactly sure when the problem surfaced. I just know that I used to get little red bubbles in my unit test next to the failing asserts and that no longer seems to happen. Is there a way to restore this? I've been trying to use Apple's own SenTesting framework instead of GoogleTools for mac like I used to. Should I revert to Google Tools? Does anyone have an answer?
