About MKMapView category
The included MKMapView category for supporting zoom level, code belongs to Troy Brant - http://troybrant.net/blog/2010/01/mkmapview-and-zoom-levels-a-visual-guide/
If you have ever built a web application using the Google Maps API, you are likely intimately familiar with this line of code:
map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13);
To implement this you can use the attached category.
In your view controller where you declare MKMapView simply import "MKMapView+ZoomLevel.h"
MKCoordinateRegion region; CLLocationCoordinate2D c; c.latitude = 37.4419; c.longitude = -122.1419; region.center = c; [mapView setCenterCoordinate:c zoomLevel:13 animated:YES];
To get the current zoom level
int level = [mapView zoomLevel];
