Intercepting pan gestures over a UIScrollView breaks scrolling

Question

I have a vertically-scrolling UIScrollView. I want to also handle horizontal pans on it, while allowing the default vertical scroll behavior. I\'ve put a transp

Answer 1

I had the same problem to solve and I did this:

1) Attach my own pan recognizer to the scroll view.

2) Return YES on: – gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:

This will allow both gestures to work. So what that means is that on vertical scroll, both your panGesture delegate and scrollView Delegate will be fired. If it is a horizontal scroll, it will only call your panGesture delegate.

3) in my panGesture delegate, detect if it is a horizontal scroll, if it is not, ignore.
