title: Override Control Center screen edge pan from bottom?
body: <p>I’d like to use a <code>UIScreenEdgePanGestureRecognizer</code> on the bottom edge of my display. The recognizer works perfectly if I set its <code>edges</code> to <code>UIRectEdgeLeft</code> or <code>UIRectEdgeRight</code>, but <code>UIRectEdgeTop</code> or <code>UIRectEdgeBottom</code> do not work – they’ve overridden by some <code>UISystemGestureGateGestureRecognizer</code>.</p>
  
  <p>I’m actually trying to override the Control Center in the same way that Facebook Paper has managed to do – figured the screen edge pan may have been their trick. Paper allows you to scroll from the bottom screen edge to pull their menu up, and Control Center doesn’t pop up at all. It’s definitely possible, I’m just wondering how they’ve done it.</p>
  
  <p>Any thoughts?</p>
