I have successfully integrated the three20 framework in my project, and I have extended the TTPhotoViewController to add some further functionality.

Now I need to add some subviews to the TTPhotoView loaded by the TTPhotoViewController. In particular I would like to add that subviews after every TTPhotoView as been loaded. These subviews represents sensible area over the image so they should scale proportionally with the image. The user can tap a subview to get extra info about the image.

I don't know how to implement this behavior. Should I extend the TTPhotoView and make sure that the TTPhotoViewController use this extended version instead of its TTPhotoView?

Could someone point me to the right direction? Thank you
