Discussion
Implement this method in your swipe controller and return true to inform views that perform elastic scrolling to forward gesture scroll events up the responder chain. The events are forwarded only on the following condition: the content to be scrolled is already at the edge of the scrolled direction when the scroll gesture begins. Otherwise, the view performs elastic scrolling. The default implementation returns false.
