A Facebook image picker providing a simple UI for a user to pick photos from a users Facebook account. It provides an image picker interface that matches the iOS SDK's UIImagePickerController.
that is one of the steps.
iirc, the main reason for all of this was to dismiss the view automatically when an item is selected in single selection mode.
Couldn't this be achieved more easily just by setting allowsMultipleSelection to NO in the PhotoViewController?
