Navigation problem with view controllers.

Question

Hi All

I have some problem with the my view controllers. When i have about 50 or more records in one of my table view which is below in the stack of view controllers and if i tap the back button quickly the navigation bar on the tap changes but the view does't change.

For example:

if i have the search controller below in the stack and detail controller up in the stack in this case on tapping the back button quickly the navigation bar comes to the search but the view controller remains on detail page.

can any one can give me cause or solution of this problem.

your help will be highly appreciated.
