A bar button item is a button specialized for placement on a UIToolbar or UINavigationBar objects. 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.

iOS includes a number of system-provided items with specific icons, but developers can create custom items as well.
