c4

What I'm hoping to achieve is to call a method in C4Workspace.m by using: [shape addGesture:SWIPELEFT name:@"swipeLeft" action:@"leftSwipeMethod"]; I know that this attempts to call a method called "leftSwipeMethod" within the C4Shape class, but in the documentation it also mentions you can call methods from the super class (which is what I think I'm trying to do?).
