Differentiate pinchs from counterpinchs with UIPinchGestureRecognizer

Question

It's possible to differientate bettwen a pinch gesture and a counterpinch gessture with UIPinchGestureRecognizer ?

And it's possible to know the angle bettwen the two fingers that perform the pinch using UIPinchGestureRecognizer ?

thanks.

Answer 1

The scale returned from the pinch will be less than one on a "zoom out" and greater than one on a "zoom in". There is no way to get the angle between the two fingers from the UIPinchGestureRecognizer; for that you'd have to track the touches manually.
