This error doesn\'t make sense, as the preferred orientation UIInterfaceOrientationLandscapeRight is returned by the supported orientation
UIInterfaceOrientationLandscapeRight
//iOS
from the documentation:
-(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft; }
Note that the correct orientation is "Mask"! Did you try this?
