Not sure if what I want to do makes sense, but I want to take advantage of the UITabBarController and the TTNavigator from Three20. Any tutorials around that demonstrate how this can be done? I understand how to add view controllers to the navigator using the TTURLMap, but do I need to add a navigator for each tabbar item? I'm lost.
Take a look at the Three20 TTNavigator Demo. It shows you how to use Three20 with a UITabBarController.
