pop a specific view controller

问题

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?

thanks,

Nava

回答1:

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.

回答2:

Simply make the action of a UIBarButtonItem on your UINavigationController (in this case, most likely your rightBarButtonItem) call

[self.myNavController pushViewController:view1 animated: YES];
