title: Limit touch event to view
body: <p>I have a view with two swipe gesture recognizers. One left and one right.</p>
  
  <p>On top of this view, i have another view with two other swipe gesture recognizers.</p>
  
  <p>My problem is that any swipe i do on the second view gets sent to the parent view as well.</p>
  
  <p>How do i prevent this? 
  And, how do i prevent a touch event triggered in child view B from getting sent to parent view A?</p>
  
  <p>thanks!</p>
  
  <p>ps. sorry if this question was asked before.. i did try a bunch of stuff before asking, but nothing worked ..</p>
