xcode6 - Image inside a framework not shown in iOS 7 -

I created a coco-touch framework that included a customized UIViewController with Xib in a XIV. There is an image inside xcassets framework. And it will be shown in the customized UIViewController It works well in the iOS 8 simulator but when I run it in the iOS 7 simulator (build framework for iOS 7), custom UIIUIUIUIUUT-controller has been loaded properly and is shown. But the image inside is not showing? Any remedy? Thank you.

Inside my favorite view controller:

  - (instancetype) init {NSBundle * bundle = [NSBundle bundleForClass: [MyViewController class]]; If (self = [super initvittnibnames: @ "myvücüntürer" bundle: bundle]) {} return self; }  

and my app which loads the UIViewController from the framework:

  MyViewController * vc = [MyViewController alloc] init]; [Self-present ViewController: animated vc: yes complete: ^ {}];
