Current version of Twiiter has a tab bar as shown below.

When I select a tab , it shows selected tab as pushed (deeper tab).
I want to implement same kind of tab bar in my iphone app for iOS 5.
How can I implement it ? Any knid of help is highly appreciated.
Thanks
You need create the image with the deeper look yourself and set the
selectionIndicatorImageproperty on theUITabBar.It’s probably easiest to set this up using the appearance proxy in your AppDelegate:
[[UITabBar appearance] setSelectionIndicatorImage:yourImage];
