A bar button item is a button specialized for placement on a UIToolbar or UINavigationBar object. It inherits basic button behavior from its abstract superclass, UIBarItem. The UIBarButtonItem defines additional initialization methods and properties for use on toolbars and navigation bars. You typically use Interface Builder to create and configure bar button items.
