  <p>here is some of my code :</p>
  
  <pre><code>- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
  
      location = newLocation.coordinate;
  
  
      MKCoordinateSpan span;
      if (shouldAdjustZoom) {
          //use the manually defined span
          span.latitudeDelta=.005;
          span.longitudeDelta=.005;
          mapRegion.span = span;
      }
      else {
          mapRegion=mapView.region;
          mapRegion.center=newLocation.coordinate;
          mapView.region=mapRegion;
      }
  
      // Apply new coordinates
      [mapView setRegion:mapRegion animated:TRUE];
  
  }
  </code></pre>
