pop a specific view controller
I have an hierarchy of 3 view controllers in my navigation bar controller: view1->view2->view3. After the user finished with view3 I want to take him to view1. What is the best approach to do that?
Assuming that view3 and view2 have already been pushed onto your navigation controller, you can use -[UINavigationController popToRootViewControllerAnimated:] or -[UINavigationController popToViewController:animated:] to accomplish this.
