title: iOS set MKMapView center so supplied location is in the bottom center
body: <p>I have a MKMapView and a never changing CLLocationCoordinate2D. What I am trying to do is center the map so that this coordinate will be placed at the bottom center of the map. I am able to center the map on this coordinate with the simple:</p>
  
  <pre><code>MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(mapCenter, 10000, 10000);
  [self.mapView setRegion:viewRegion animated:YES];
  </code></pre>
  
  <p>But how can I make it so that the map centers on the point that would make this mapCenter coordinate be placed at the bottom of the map? I would like it to work regardless of the initial zoom level of the map if possible.</p>
