App shows black screen on ipod

Question

This app is universal and running perfectly fine on all other devices except iPod. I've used two storyboard.

This is the code which i've written in the AppDelegate.

 -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
 {    
    UIImage* background = [UIImage imageNamed:@"navigation-bar-background"];
    [[UINavigationBar appearance] setBackgroundImage:background forBarMetrics:UIBarMetricsDefault];

    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:[[UIImage imageNamed:@"black-back-button"]resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:[[UIImage imageNamed:@"black-back-button-landscape"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)] forState:UIControlStateNormal barMetrics:UIBarMetricsLandscapePhone];

    [[UISlider appearance] setThumbImage:[UIImage imageNamed:@"knob-button"] forState:UIControlStateNormal];
    return YES;
}

Answer 1

I forgot to add the main storyboard in the project.So,if anyone else get into the same problem then double check whether you have added a storyboard in main storyboard.

Answer 2

Just change the image(make sure the new trial image is png formatted) and see if it is showing.

Maybe .. your iPod capabilities.. are not "compliant" (armv7, etc) with your release code What iPod generation? Check - again - your iPod capabilities: http://blog.manbolo.com/2012/10/30/uirequireddevicecapabilities-and-device-compatibility-matrix

Answer 4

There is a problem in how Xcode and how it generates the defaults when handling the storyboards in universal apps. Checkout this answer: https://stackoverflow.com/a/21632289/703530
