From the Apple's Tabbar documentation:
A tab bar is a control, usually appearing across the bottom of the
screen in the context of a tab bar controller, for giving the user
one-tap, modal access to a set of views in an app. Each button in a
tab bar is called a tab bar item and is an instance of the
UITabBarItem class. If you instead want to give the user a bar of
buttons that each perform an action, use a UIToolbar object.
The UITabBar class supports user customization of a tab bar by
reordering, removing, and adding items to the bar. You can use a tab
bar delegate to augment this behavior.
Use the UITabBarItem class to create items and the setItems:animated:
method to add them to a tab bar. All methods with an animated:
argument allow you to optionally animate changes to the display. Use
the selectedItem property to access the current item.
You are using UIBarbuttonItems in a tab bar. If you want to use a tab bar use UITabBarItems.
However, seeing that you are adding actions to the buttons, you should be using a toolbar, not a tab bar. It should work peachy if you make these changes!
