Horizontal UISwipeGestureRecognizer in subview of UIScrollView ? (UIScrollView only needs to recognize vertical scrolling)

Question

I have a UIScrollView where I added a subview. The scrollview scrolls fine vertically and that is all it should do. I would now like to recognize left/right swipes in the subview with the help of a UISwipeGestureRecognizer. I know it is possible, but I have not come across a solution and several tries have been unsuccessful.

Answer 1

Try these:

• Set the delegate of your UIGestureRecognizer and

• Implement shouldRecognizeSimultaneouslyWithGestureRecognizer:

  -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
  return YES;
  }
  

• Implement shouldReceiveTouch:

  - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
  {
   return YES;
  }
  

Hope this helps
