Use viewWillTransitionToSize:withTransitionCoordinator: like so:

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{
    [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];

    // Will rotate

    [coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        // Will animate rotation
    } completion:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        // Did rotate
    }];
}

You should take a look at the WWDC 2014 video "View Controller Advancements in iOS 8" where this is discussed.

Are you using storyboards? If so, you may have old code in your application didFinishLaunchingWithOptions method.

Try removing the following line of code and any others to do with UIWindow:

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

Others have said to remove lines from your plist file but that shouldn't be necessary.
