Check whether zoom level changed

Question

I\'m using MapKit on iPhone. How can I know when the user changes the zoom level (zoom in\\out the map)?

I\'ve tried to use mapView:(MKMapView *)mapView regi

You could save a latitude delta, then when regionDidChangeAnimated: is called, check to see if the new latitude delta is different. I think the latitude delta stays constant as long as the map isn't zoomed.
