Finding pinch-in or pinch-out in UIPinchGestureRecognizer

Question

I'm using UIPinchGestureRecognizer on view, now I have a requirement of knowing whether pinch-in is performed or pinch-out is performed in my selector method. Either of 1 among at a time. Please give me some idea to obtain this. Thank you.

Answer 1

Use the .scale property on the gesture:

• >1 pinch out
• <1 pinch in
