public final class UINavigationControllerOperation
extends java.lang.Object
Most clients will not need to subclass UINavigationController.
If a navigation controller is nested in a tab bar controller, it uses the title and toolbar attributes of the bottom view controller on the stack.
UINavigationController is rotatable if its top view controller is rotatable. Navigation between controllers with non-uniform rotatability is currently not supported.
