Another solution how I solved this problem.

Define the current Orientation:

@interface AJImageCollectionViewController (){
    UIInterfaceOrientation _currentOrientation;
}
@end

Then check the orientation in the viewWillLayoutSubviews:

- (void)viewWillLayoutSubviews {
    [self checkIfOrientationChanged];
}

- (void)checkIfOrientationChanged {
    UIInterfaceOrientation newOrientation = [[UIApplication sharedApplication] statusBarOrientation];
    BOOL newOrientationIsPortrait = UIInterfaceOrientationIsPortrait(newOrientation);
    BOOL oldOrientationIsPortrait = UIInterfaceOrientationIsPortrait(_currentOrientation);

    // Check if the orientation is the same as the current
    if(newOrientationIsPortrait != oldOrientationIsPortrait){
        _currentOrientation = newOrientation;
        // Do some stuff with the new orientation
    }
}
