title: MKMapView causes Lag when scrolling while it is rendering/loading map
body: <p>I have a ScrollView that contains an MKMapView in it, I noticed a lag while scrolling while the mapView is still loading/rendering. But the lag is gone once its fully loaded.</p>
  
  <p>Is there anyway to solve this?</p>
  
  <p>Thank you </p>
  
  <p>Heres how I add it</p>
  
  <pre><code>var location: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: latitude.doubleValue, longitude: longitude.doubleValue);
  var span: MKCoordinateSpan = MKCoordinateSpanMake(0.1, 0.1);   
  
  var region: MKCoordinateRegion = MKCoordinateRegion(center: location, span: span);
  
  var mapView:MKMapView = MKMapView(frame: CGRect(x: 0, y: 0, width: 320, height: 140));
  mapView.setRegion(region, animated: false);
  scrollView.addSubview(mapView);
  </code></pre>
