Protocols

A protocol to communicate to the transition that an update of the snapshot view is required. This is adopted only by the presentation controller of any view controller presented using DeckTransition

A set of methods that vend objects used to customize a DeckTransition presentation’s swipe-to-dismiss behaviour.

The transition has an internal heuristic to determine which UIScrollView should be tracked for the swipe-to-dismiss gesture. However that has some edge cases, which can we worked around by making your modal view controller and view controllers presented by or contained within it conform to this protocol.
