Update dismiss image

[luisfsresende]

I'm presenting a scrollview and if I scroll down and then dismiss the view the image for the animation shows the top of the view.

How can I update the image while I scroll?

MRFlipTransition has a instance method updateContentSnapshot:afterScreenUpdate:
And you can get the instance from the view controller you presented by
MRFlipTransition *animator = self.transitionDelegate

I think you can come over by yourself for the rest of the steps.
