Questions similar to this have been asked all over, but I haven't been able to find a solution to my specific problem, so here goes.
I have a UIViewController with a UIScrollView in its view. Within the scrollview, I have a number of regular uiview subviews. I want to be able to detect whether the scrollview swipe was with one or two fingers, and to cancel the scroll and call some other method in one of those cases. Can anyone help me with this?
