How to move a MKAnnotation without adding/removing it from the map?

Question

Is it possible to move the coordinate of a MKAnnotation without adding and removing the annotation from the map?

Answer 1

After you update the coordinates or some other properties of the annotation, just call following MKMapViewDelegate method to redraw your annotation:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation;

e.g.:

myAnnotation.coordinate = CLLocationCoordinate2DMake([newLat doubleValue], [newLon doubleValue]);
[self mapView:self.mapView viewForAnnotation:myAnnotation];
