NavigationBar

super: UINavigationController (on iOS)

The NavigationBar class implements a specialized view controller that manages the navigation of hierarchical content. This navigation interface makes it possible to present your data efficiently and makes it easier for the user to navigate that content. You generally use this class as-is but you may also subclass to customize the class behavior.

The screens presented by a navigation interface typically mimic the hierarchical organization of your data. At each level of the hierarchy, you provide an appropriate Window to display the content at that level.

  • Load() This event is called when the object becames available in the current runtime system.

  • WillShow() Use this event to be notified when navigation is about to be added to a view hierarchy.

  • DidShow() Use this event to be notified when navigation was added to a view hierarchy.

  • WillHide() Use this event to be notified when navigation is about to be removed from a view hierarchy.

  • DidHide() Use this event to be notified when navigation was removed from a view hierarchy.

  • Unload() This event is called when the object has been removed from the current runtime system (but not yet deallocated).
