I am attempting to get a UIGestureRecognizer working with a UIWebview which is a subview of a UIScrollView. This sounds odd but when I have the numberOfTouchesRequired set to 2 the selector fires, but when numberOfTouchesRequired is set to one the selector doesn't fire.

I want to know if there is a way to restrict the size or movements of the UIViews in the GestureRecognizers. Sure I could write my own restriction code but wana know if we can set some property or something to have some bound limits.

In my iPhone app, I require to recognize the swipe gesture made by the user on the view.
