  • View doesn't respond to touches after shake

    - by Mike Rychev
    In my app I've implemented a shake event and it shows a UIImageView. When the UIImageView is shown, I hide the Nav Bar with: [self.navigationController setNavigationBarHidden:YES animated:NO]; And after that I want to bring it back when user touches the screen: - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [[self navigationController] setNavigationBarHidden:NO animated:YES]; } But it doesn't work! Like my view doesn't respond to touches. Thanks in advance!

  • AdMob ad is showing in iOS simulator, but not on iDevice

    - by Ben Toscano
    As the heading states, I can get my AdMob Ad to show in the iOS 5.1 and 6.0 simulator just fine, however, when running my application on my iOS 5.1.1 or 6.0 devices, there is just a blank space where the ad should be served. The code in my .m file is as follows: bannerView_ = [[GADBannerView alloc] initWithFrame:CGRectMake(0.0, 411.0 - GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)]; bannerView_.adUnitID = @"**myID**"; bannerView_.rootViewController = self; [self.view addSubview:bannerView_]; [bannerView_ loadRequest:[GADRequest request]]; //GADRequest *r = [[GADRequest alloc] init]; //r.testing = YES; //[bannerView_ loadRequest:r]; Furthermore, if I initiate testing of ads (see commented-out section), the test ad shows on both the simulator AND my iDevices, which is baffling me! What am I missing? Thanks for your help.

  • UIWebView in multithread ViewController

    - by Tao
    I have a UIWebView in a viewcontroller, which has two methods as below. The question is if I pop out(tap back on navigation bar) this controller before the second thread is done, the app will crash after [super dealloc], because "Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread.". Any help would be really appreciated. -(void)viewDidAppear:(BOOL)animated { [super viewWillAppear:animated]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(load) object:nil]; [operationQueue addOperation:operation]; [operation release]; } -(void)load { [NSThread sleepForTimeInterval:5]; [self performSelectorOnMainThread:@selector(done) withObject:nil waitUntilDone:NO]; }

  • Animate a GIF using Core Animation layers?

    - by Cliff
    I'm trying to animate a GIF and I hit a roadblock. I have an example of what I'm trying to do that uses the individual frames of the GIF and setting the animationImages property of a UIView. However in my project, the thing I want to animate is drawn using Layers. I'm looking for a quick and easy way to animate the frames without introducing too much complexity. Is there any animationImages equivalent with Layers? Does anybody have any ideas?

  • How to reference THE UIWindow from sub UIViewControllers?

    - by maralbjo
    I am trying to add another subview programmatically based on some event (user taps a button, for instance). My problem is that I am having problems referencing the (one and only) instance of UIWindow. I reach it from my appDelegate, because the MainWindow.xib and the appDelegate have been wired up. But I cannot reach the UIWIndow from anywhere else (I cannot draw that connection in IB, can I?) What techniwue is preferred to get a reference to (the one and only) UIWindow? ...so that I in turn can use the following code from my various UIViewControllers: [myOneAndOnlyWindow addSubview:oneOfManyViews.view]; [myOneAndOnlyWindow makeKeyAndVisible];

  • How can I release this NSXMLParser without crashing my app?

    - by prendio2
    Below is the @interface for an MREntitiesConverter object I use to strip all html tags from a string using an NSXMLParser. @interface MREntitiesConverter : NSObject { NSMutableString* resultString; NSString* xmlStr; NSData *data; NSXMLParser* xmlParser; } @property (nonatomic, retain) NSMutableString* resultString; - (NSString*)convertEntitiesInString:(NSString*)s; @end And this is the implementation: @implementation MREntitiesConverter @synthesize resultString; - (id)init { if([super init]) { self.resultString = [NSMutableString string]; } return self; } - (NSString*)convertEntitiesInString:(NSString*)s { xmlStr = [NSString stringWithFormat:@"<data>%@</data>", s]; data = [xmlStr dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]; xmlParser = [[NSXMLParser alloc] initWithData:data]; [xmlParser setDelegate:self]; [xmlParser parse]; return [resultString autorelease]; } - (void)dealloc { [data release]; //I want to release xmlParser here but it crashes the app [super dealloc]; } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)s { [self.resultString appendString:s]; } @end If I release xmlParser in the dealloc method I am crashing my app but without releasing I am quite obviously leaking memory. I am new to Instruments and trying to get the hang of optimising this app. Any help you can offer on this particular issue will likely help me solve other memory issues in my app. Yours in frustrated anticipation: ) Oisin

  • Why am I getting two section headers on this grouped table?

    - by Andy
    I'm sure this is some easy-to-fix issue that I've missed, but I can't figure it out. I've got a grouped table view with 3 sections. I'm using the following code to generate section headers: -(NSString*)tableView:(UITableView*)tableView titleForHeaderInSection:(NSInteger)section { if (section == 0) { NSString *header = @"Header 1"; return header; } if (section == 1) { NSString *header = @"Header 2"; return header; } else { NSString *header = @"Header 3"; return header; } } When my table is displayed, there are two headers for each section - one with white text on a gray bar that stretches across the screen (like the letter separators in the Contacts app), and one in gray text on the table background (which is the one I want). Both headers have identical text. Where is the first header coming from?

  • Enable editing does not call didSelectRowAtIndexPath ??

    - by elementsense
    Hi I have a UITableViewController where the user should be able to edit the items. In order to enable editing i use this : self.navigationItem.rightBarButtonItem = self.editButtonItem; And for everyone, how does not know where self.editButtonItem comes from, it is predefined by the SDK. So, now when I press on any item, this method is called : - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath but as soon as I hit the edit button and while editing is active, this method does not seemed to be called. Any idea what I missing ? This is the rest of the code that is related to editing : // Override to support conditional editing of the table view. - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { // Return NO if you do not want the specified item to be editable. return YES; } - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { return UITableViewCellEditingStyleNone; } - (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath { return NO; } Thanks for the help. mcb

  • Why call autorelease for iVar definition in init method?

    - by iFloh
    Hi, I just familiarise myself with the CLLocationManager and found several sample class definitions that contain the following init method: - (id) init { self = [super init]; if (self != nil) { self.locationManager = [[[CLLocationManager alloc] init] autorelease]; self.locationManager.delegate = self; } return self; } - (void)dealloc { [self.locationManager release]; [super dealloc]; } I don't understand why the iVar would be autoreleased. Does this not mean it is deallocated at the end of the init method? I am also puzzled to see the same sample codes have the iVar release in the dealloc method. Any thoughts? '

  • UIActionSheet cancel button strange behaviour

    - by nevan
    I have a UIBarButtonItem opening an action sheet to offer users choices about what to do. Everything works as expected unless I try to click on the "Cancel" button. The target of the button appears to have moved up from where it should be. I can only activate it by clicking somewhere in the middle of the "Cancel" and "Ok" buttons. I've tried at action sheets in other applications and they work fine, so it's not just my big thumb. The action sheet is opening in a UIViewController - (void)showOpenOptions { UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"Open link in external application?", @"Open in external application") delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", @"Cancel") destructiveButtonTitle:NSLocalizedString(@"Open Link", @"Open Link") otherButtonTitles:nil]; [sheet showInView:self.view]; [sheet release]; }

  • TextField Covering UIAlertView's Button.

    - by XcodeDev
    Hi, I am using a UIAlertView with three buttons: "Dismiss", "Submit Score" and @"View Leaderboard". The UIAlertView also contains a UITextField called username. At the moment the UITextField "username" is covering one of the buttons in the UIAlertView. I just wanted to know how I could stop the UITextField from covering one of the buttons, i.e move the buttons down. Here is an image of what is happening: And here is my code: [username setBackgroundColor:[UIColor whiteColor]]; [username setBorderStyle:UITextBorderStyleRoundRect]; username.backgroundColor = [UIColor clearColor]; username.returnKeyType = UIReturnKeyDone; username.keyboardAppearance = UIKeyboardAppearanceAlert; username.placeholder = @"Enter your name here"; username = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)]; username.borderStyle = UITextBorderStyleRoundedRect; [username resignFirstResponder]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Congratulations" message:[NSString stringWithFormat:@"You tapped %i times in %i seconds!\n", tapAmount, originalCountdownTime] delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"Submit To High Score Leaderboard", @"View Leaderboard", nil]; alert.tag = 01; [alert addSubview:username]; [alert show]; [alert release];

  • -(void)dealloc - How ? Objective - C

    - by sagar
    Please Note that - this is not similar than this question. OK. To understand my question, First of all please see both of these destructors. - (void)dealloc { [Marketdetails release]; Marketdetails=nil; [parsedarray release]; parsedarray=nil; [Marketid release]; Marketid=nil; [marketname release]; marketname=nil; [super dealloc]; } - (void)dealloc { [super dealloc]; [Marketdetails release]; Marketdetails=nil; [parsedarray release]; parsedarray=nil; [Marketid release]; Marketid=nil; [marketname release]; marketname=nil; } See, Both destructors have different code. In First Destructor first current class objects are released & then [super dealloc] is called. In second Desctructor first [super dealloc] is called. My question is as follows. Where should we write [super dealloc] ? first or last ? or it doesn't matter ?

  • Simple ViewController / View, remove white bar?

    - by fuzzygoat
    I am just looking at setting up a simple viewController programatically, I have a ViewController.xib file that I have set the background color to RED in interface builder. I have also added the following to my AppDelegate.m @implementation syntax_MapViewAppDelegate @synthesize window; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { viewController = [[MapViewController alloc] init]; [window addSubview:[viewController view]]; [window makeKeyAndVisible]; return YES; } -(void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end When I run the code it does what I expect apart from the white bar at the bottom of the screen, can anyone give me any pointers in how to remove this? I have a feeling I might need to position the view within the window, but I am not sure how? cheers Gary
