TTNavigationController not working

I have downloaded the latest build of the three20 library but i开发者_如何学JAVAt doesn't include the TTNavigationController. I looked through the files on github and found the classes there though. So I downloaded them but now I can't find it's parent class TTBaseNavigationController anywhere. Does anybody know what's going on with the three20 build I got?

You need to import following

#import <Three20/Three20.h>

The Three20.h file includes Three20UI.h, which contains the TTNavigationController.

If you are using xcode 4, see the following instruction on importing the Three20 project into your project and setting up appropriate dependency, HEADER SEARCH PATHS and static lib linking.
