For my app's loading screen and splash screen, I used up with two different methods to display my iPhone 3, iPhone 4 and iPhone 5 images appropriately. For the loading screen, simply adding -568h@2x to your image is enough to support iPhone5. For the splashscreen, I used a series of (if height == ) cases to check the height of the UIScreen's bounds and sourced the appropriate image to the image view. It was apparent to me here that the -568h isn't universally recognized as an iPhone 5 image. It is only applicable to the loading screen. Now, in my AppDelegate, I'm setting a the background image

I'm having memory issues with one of my apps and I've identified "Real memory" as defined in Instruments> Activity monitor as a possible culprit. My app allocates large UIImages within UIScrollViews . There's a CIImageFilter applied to one of the images. Activity monitor shows that upon the first pushing of the view controller containing scrollviews with large images, the real memory use jumps to around 300mb. Subsequent pushes/pops raise it to about 500mb: I read that "Live Bytes" does not count memory used by textures and CALayers, so my question is: How do I properly release memory that is

When i run my project at iOS 5.1 simulator , it shows yld: lazy symbol binding failed: Symbol not found: _objc_setProperty_nonatomic_copy Referenced from: /Users/apple/Library/Application Support/iPhone Simulator/5.1/Applications/3A003E5F-2C66-494F-BCC1-C3EE82F01464/dogTree.app/dogTree Expected in: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/System/Library/Frameworks/Foundation.framework/Foundation And I don't have 5.1 SDK. But why library search path is 5.1 not 6.0? All my project and be run at iOS 6.0 device, but when I

You can set the autocapitalizationType property of a UITextField so all input is in upper case. I find that does work fine on the simulator (when actually tapping the simulator's keypad, not the Mac's keyboard), but not on the device? Everything stays lowercase. In the UICatalog demo I added to the textFieldNormal method: textFieldNormal.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters; Added a delegate too, to display the actual autocapitalizationType for the UITextField: - (void)textFieldDidBeginEditing:(UITextField *)textField { NSLog( @"textField.autocapitalizationType=%d

I tried to: - (IBAction)delete:(UIButton*)sender{ NSIndexPath *indexPath = [self.collectionView indexPathForCell:(TourGridCell *)[[[sender superview]superview]superview]]; } But NSLog shows that cell exist, but indexpath is nil. OK, here it is: - (IBAction)delete:(UIButton *)sender{ NSIndexPath *indexPath = nil; indexPath = [self.collectionView indexPathForItemAtPoint:[self.collectionView convertPoint:sender.center fromView:sender.superview]]; } Sometimes it's the simplest possible answer. I was having exactly the same problem as @Schmidt, but was frustrated to see that his answer was to use

I am starting to learn how some iOS development at the minute and I currently have the Apress beginning IOS6 book that I am working off. In chapter two there is a simple tutorial to show two buttons and a label and when a button is pressed it is shown on the label which one was pressed. I have completed the tutorial but it has raised one question that I can't find the answer to. The tutorial uses ARC (automatic reference counting) in case that makes a difference. Here is the code, The header file: #import <UIKit/UIKit.h> @interface MTMViewController : UIViewController @property (weak,

i have an iPhone application in which i added images directory (Group) in to Resources (group). i want to access that images which is in images . I need a path to that images so i create a code like following. NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"myImage1" ofType:@"png" inDirectory:@"images"]; NSLog(@"%@", imagePath); Result : (null) i also tried this code NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"myImage1" ofType:@"png"]; But this code gives me (null) result. myImage1 's path is Resources/images/myImage1.png I don't know what is the problem.
