iPhone: UiNavigationController back button

iphone, uinavigationcontroller

Solution

`UINavigationBarDelegate` is the delegate class and it implements `-navigationBar:shouldPopItem`, since these controllers work in stacks you're just pushing or popping views. This will most likely always evaluate to true otherwise I feel a back button that does anything but pop a view controller will violate Apple's Human Interface Guidelines.
