How to customize the size of a UITabBarController?

Is there any way to force a UITabBarController to 开发者_开发技巧be a size less than the full Window size on an iPhone? I noticed if I change its frame size & origin that works until it seems to resize itself.

You are better off by creating a customTabBarController and setting

 -(UITabBar *) tabBar { 
return nil; 
} 

And thereupon add your custom TabBar in viewDidLoad of customTabBarController. Here you could have the frame, background color, autoresize of your choice.
