Is this an iOS 8 Bug (orientation issue on rotation)?

Question

since iOS 8 my App runs quite good, but I found a Problem while testing this app. It just happens on iPad and only if I launch the app in landscape mode. If it launches in Portrait everything is right(no rotation issues). If i rotate the Device (simulator or real device) the view rotates out of the screen and just shows a Cut of the real view and the rest is black.

Anyone else did notice such a bug? How can I fix it?

Answer 1

Had similar problem. Surprisingly the fix was to comment out all the code related to self.window on Appdelegate.

Commented initialising of self.window and its assignment. Set the initial view in storyboard in Attributes inspector by checking "Is Initial View Controller" checkbox.

New Better Solution
Commenting self.window was causing other issues. Instead the below code is best:

- (void)applicationDidChangeStatusBarOrientation:(NSNotification *)notification 
    {
         [UIViewController attemptRotationToDeviceOrientation];
    }

Answer 2

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
BOOL landscape = (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight);
NSLog(@"Currently landscape: %@, width: %.2f, height: %.2f", 
      (landscape ? @"Yes" : @"No"), 
      [[UIScreen mainScreen] bounds].size.width, 
      [[UIScreen mainScreen] bounds].size.height);

And the results are: For iOS 8+

Currently landscape: No, width: 320.00, height: 568.00
Currently landscape: Yes, width: 568.00, height: 320.00

and for iOS 7-

Currently landscape: No, width: 320.00, height: 568.00
Currently landscape: Yes, width: 320.00, height: 568.00

It seems like there is a change in the way height and width of the screen is handled while in portrait and landscape from ios8 onwards.
