Open source UIView with browser-like tabs for iOS

Is there an open source UIView component that supports mu开发者_如何学Pythonltiple, dynamic tabbed views for the iPhone (iPad) SDK? I see several apps in the iPad App Store which utilize tabs, one such example is the Atomic Web Browser which provides a tabbed browsing experience (like Safari on the Mac or Firefox). Instead of reinventing this functionality, I'd like to reuse an existing component.

I found an open source (MIT license) solution at Cocoa Controls: BHTabBar for iOS.

Did you have a look into the Three20 framework. I haven't use it but maybe it suits your needs.
