Glitchy transition while pushing and popping using UINavigationController

Question

I am using UINavController to push and pop between viewcontrollers. However when I push and pop the animation is not smooth. The navbar backbutton transition happens first and then the view and its title. This lapse in timing makes it look as if a block appears between two views. I am not doing anything fancy and I commented out code from viewwillappear and viewdidappear, but still the problem occurs.

Has anyone seen such a problem or have a suggestion. Thanks.

Answer 1

ok, the problem is with an image view I added to the view to hold the background image. It does not move in sync with the view.
