I have an app working well on all iPhone/iPad devices with iOS 6 and above, but not on iPod-Touch running the same version iOS. Investigated and found that NO UIViewController subclass functions are called at all. Here are the function called comparison between iPhone and iPod-Touch:

iPhone, called in sequence:

UIViewController::initWithCoder
UIApplicationDelegate::didFinishLaunchingWithOptions
UIViewController::viewDidLoad
UIViewController::viewWillAppear
UIApplicationDelegate::applicationDidBecomeActive

but with iPod Touch, NO UIViewController functions are called:

UIApplicationDelegate::didFinishLaunchingWithOptions
UIApplicationDelegate::applicationDidBecomeActive

as a result on iPod there is nothing displayed and the app hangs. All suggestions are appreciated.

Really don't think I should do this to make it work but it works finally:

and

My App shows only a black screen on iPod
