title: Disable double tap zoom in MKMapView (iOS 6)
body: <p>in ios 5 i was able to disable the double tap zoom by just overriding it with a new double tap gesture. But it seems that the double tap gesture is no longer in the gesturerecognizer array that comes with the mkmapview.</p>
  
  <pre><code>NSArray *gestureRecognizers = [_mapView gestureRecognizers];
  for (UIGestureRecognizer *recognizer in gestureRecognizers) {
      NSLog(@"%@", recognizer);
  }
  </code></pre>
  
  <p>returns nothing in ios 6, where in ios 5 it would return 2 recognizers, one for single tap and one for double tap.</p>
