Replace window.rootViewController with animation works partially

Question

I'm trying to replace the window rootViewController with animation and it only works partially.

I create a UINavigationController programatically -

UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"InboxStoryboard" bundle:nil];

UIViewController *innerViewController = [storyBoard instantiateViewControllerWithIdentifier:@"centerView"];
UINavigationController *centerView = [[UINavigationController alloc] initWithRootViewController:innerViewController];

Afterwards I replace the window root view controller wrapped in an animation block -

[UIView transitionWithView:self.viewController.view.window
                  duration:0.5
                   options: UIViewAnimationOptionTransitionFlipFromLeft
                animations:^{
                    self.viewController.view.window.rootViewController = centerView;
                }
                completion:nil];

What happens is that the animation happen but the controller that I create is only partially visible, take a look at the following picture -

So as you can see during the rotation the view is only partially rendered.

Anyone bumped into this kind of behaviour before?

Answer 1

So after a long search I found the problem was in the [UIView transitionWithView:...] Searching a bit more in stackoverflow I found Swapping rootViewController with animation

Using [UIView transitionFromView:..] works perfectly.

The new code -

[UIView transitionFromView:self.window.rootViewController.view
                    toView:self.centerViewController.view
                  duration:0.5
                   options:UIViewAnimationOptionTransitionCurlUp
                completion:^(BOOL finished)
                {
                    self.window.rootViewController = self.centerViewController;
                }];
