I have the following code:

    UIScreenEdge         


        

Answer 1

I think it's a bug in iOS, which I can confirm on an iPad mini 2 and an iPad Air on iOS 7 or higher, even on the Home Screen.

In "Landscape Left" (Home button on the left) a "Right Edge Gesture" from outside the Screen is not working for me. Test it by your self on the Home Screen.

I reported a bug to Apple 9 Month ago, but noting further happened.

Update:

I played a bit with the UIWindow init and when it is a bit bigger than it really is, the Gesture works. Of course this is a horrible fix.

self.window = [UIWindow new];
self.window.rootViewController = [[UIViewController alloc] init];

// Real Size
CGRect frame = [UIScreen mainScreen].bounds;

// Real Size + 0.000001
self.window.frame = CGRectMake(0, 0, frame.size.width+0.000001, frame.size.height+0.000001);
[self.window makeKeyAndVisible];
