How to access custom view controllers in Three20 Package in iPhone?

Question

Hi friends,

I have implemented three20 projects in my application. And i have createdgrid view(Thumbnail view) and displayed the images using Three20. On clicking it, the selected image will be shown in the next view using TTPhotoViewController. Now i want access my view controller in the TTPhotoViewController class.

For Eg, i want to access "EmailviewController". If i declare in TTPhotoViewController.m ,

         #import "EmailviewController.h" --> No Such File or Directory.

So is any possible to access the view controllers in Three 20 package, If yes please guide me to how can i access?

Thanks!
