I notice something strange happens to one of my view controller: the back button disappears, yet it's possible to go back to previous view controller by tapping the top left corner (i.e where the button should reside).

In my entire file there's no line that set self.navigationItem.hidesBackButton to YES; also NSLog prints 0 as self.navigationItem.hidesBackButton's value in viewDidLoad.

This occurs in both the simulator and real device. Any ideas?
