由 ⅰ亾dé卋堺 提交于 2019-12-06 02:51:46
I'm creating a path (MKPolyline) based on the position of annotations added by the user. I want to allow the users to change the path by dragging the pins. I currently can do that, but the MKPolyline doesn't update until the pin is dropped. I implemented - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)annotationView didChangeDragState:(MKAnnotationViewDragState)newState fromOldState:(MKAnnotationViewDragState)oldState for the MKAnnotationViewDragStateDragging but it only alerts me that the user is dragging the pin and not notifing about the new position. How can I
