How to keep an MKAnnotation View Image fixed on the center of the map as the user pans and moves the map around (iOS 6)?

using iOS 6 MapKit, I would like to define an MKAnnotation (such as a pin, or a custom one) that remains fixed on the center of the map view as the user moves the map around. Once the user stops moving the map, I would like to be able to read the new coordinates of the annotation. How can I do this?

Thanks

The easiest way is to simply add your custom UIView to your MKMapView as a subview. This means when your user moves the map it will stay fixed. You will most likely have to pass through the touch events so that users can move over your custom view but worry about that later.

When your map view stops moving take its center coordinate. The MKMapView can calculate its coordinate based on its center etc [mapView centerCoordinate];
