Implementing a UITabBar in my working Three20 application

I have a working application using Three20. It basically is a bunch of nested TT开发者_开发百科ableView's.

I would like to add a UITabBar to the bottom of my app, but am not sure how to start. I used the Three20 project templates available at Three20.info

Thanks,

John

Checkout the TTNavigatorDemo that ships with three20. In particular, notice TabBarController.m, and its interaction with AppDelegate.
