title: Stealing two-finger pan from mkmapview
body: <p>I've placed a UIview above an MKMapView with the intention of stealing the two-finger pan from the map view when I am tracking a user's location. If you notice Google maps app does this on the phone as well.</p>
  
  <p>But I'm at a loss as to how to do it. I want to be able to enable it and disable it at will depending on whether the location is being tracked or not. All other gestures and touches should be passed onto the mapview</p>
  
  <p>thanks in advance.</p>
