Xcode 4.5 background image iPhone 4, 4s, 5

Question

I have in my viewController.m written the background code:

self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@\"image.png\"]];
         


        

Answer 1

iPhone 5 is retina, just like iPhone 4 and 4S, and the @2x-image will be used automatically for all these devices. It's only the startup-image that is called "-568h@2x" for iPhone 5. You need to write some code to use a different image, something like this would work:

NSString *filename = @"image.png";
CGRect screenRect = [[UIScreen mainScreen] bounds];
if (screenRect.size.height == 568.0f)
    filename = [filename stringByReplacingOccurrencesOfString:@".png" withString:@"-568h.png"];

imageView.image = [UIImage imageNamed:filename];
