pushviewController/popviewController animation duration

Question

When I push or pop a UIViewController, how long does the animation takes to complete the slide animation. I have a view on the main window, which I need to slide in sync when a ViewController is pushed or popped.

Does anyone has any idea on the type and duration of animation that takes place when I push or pop a view.

Thanks in advance.

Answer 1

Almost all animations in the iPhone are 0.3 seconds.

Answer 2

In iOS 7 and later you can have exact value by setting the UINavigationController delegate and using the method:

- (void)navigationController:(UINavigationController *)navigationController
      willShowViewController:(UIViewController *)viewController
                    animated:(BOOL)animated {
    NSTimeInterval duration = [viewController.transitionCoordinator transitionDuration];
}  

This is future proof method if the defult duration will ever change. At the moment it's value is 0.35 second.
