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"

Example

MKCoordinateRegion region;
CLLocationCoordinate2D c;
c.latitude =  37.4419;
c.longitude = -122.1419;
region.center = c;
[mapView setCenterCoordinate:c zoomLevel:13 animated:YES];

Note

To get the current zoom level

int level = [mapView zoomLevel];
