Answer 1

First allow pin to drag

- (MKAnnotationView *) mapView: (MKMapView *) mapView viewForAnnotation: (id) annotation 
{ 
    pin.draggable = YES; 
}

- (void)mapView:(MKMapView *)mapView
 annotationView:(MKAnnotationView *)annotationView
didChangeDragState:(MKAnnotationViewDragState)newState
   fromOldState:(MKAnnotationViewDragState)oldState
{
    if (newState == MKAnnotationViewDragStateEnding)
    {
        CLLocationCoordinate2D droppedAt = annotationView.annotation.coordinate;
        [annotationView.annotation setCoordinate:droppedAt];
         if(DEBUG_MODE){
        NSLog(@"Pin dropped at %f,%f", droppedAt.latitude, droppedAt.longitude);
         }
    }

}

The process is you need to allow pin to dragable, and you will get that destination's lat long on didChangeDragState of MKMapView.

Try below code.

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id < MKAnnotation >)annotation
{
    MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"ident"];
    pinView.draggable = YES;
    pinView.animatesDrop = YES;
    return pinView;
}
- (void)mapView:(MKMapView *)mapView
 annotationView:(MKAnnotationView *)annotationView
didChangeDragState:(MKAnnotationViewDragState)newState
   fromOldState:(MKAnnotationViewDragState)oldState
{
    if (newState == MKAnnotationViewDragStateEnding)
    {
        droppedAt = annotationView.annotation.coordinate;
        NSLog(@"Pin dropped at %f,%f", droppedAt.latitude, droppedAt.longitude);
    }
}
