I\'m trying to zoom a map into the user\'s current location once the view loads, but I\'m getting the error \"** * Terminating app due to uncaught exception \'NSInvalidA

......

MKCoordinateRegion region =mapView.region;

region.center.latitude = currentLocation.latitude ;
region.center.longitude = currentLocation.longitude;
region.span.longitudeDelta /= 1000.0;
region.span.latitudeDelta /= 1000.0;

[mapView setRegion:region animated:YES];
[mapView regionThatFits:region];
