Question

I have a UIViewController called FriendsViewController inside a UINavigationController. And a second UIViewController called FriendsDetailedViewController. When navigating from the first view controller to the second, I want to programmatically press the Back button when needed. How to do this?

Answer 1

Simply use

[self.navigationController popViewControllerAnimated:YES]

from FriendsDetailedViewController. Your view will be popped out i.e. the behavior of back button.

Note that it returns UIViewController on normally, and returns nil if there is nothing to pop.
