determine if MKMapView was dragged or zoomed

I just need a way to differentiate between this 2 events while playing with the map:

  1. dragging the mapview
  2. zooming the mapview

Thanks,

MKMapView is not based on UIScrollView so it doesn't call UIScrollViewDelegate methods. But nonetheless, you can instantiate UIPanGestureRecognizer and UIPinchGestureRecognizer, add them to your map view and work with their action methods.

inside MKMapView delegate methods:

- (void)mapView:(MKMapView *)mapView region{Will,Did}ChangeAnimated:(BOOL)animated

compare the "new" span with the "old" one. Something like 

MKZoomScale currentZoomScale = (CGFloat)(map.bounds.size.width / map.visibleMapRect.size.width);

in the BreadCrumb Sample Project.
