iOS mapView animatesDrop

In my mapview, I currently have the bool animatesDrop for the annotations set to NO. This is because when the mapView annotations are plotted during viewWillAppear, I don't when them animated. However, I also have a refresh button used to re-plot the annotations and would like them to animated (drop) when that is pushed. Is there a way of accomplishing this? Thanks.

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {

    if ([annotation isKindOfClass:[MKUserLocation class]]) {

        return nil;
    }

    MyPin = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"current"];

    UIButton *calloutButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

    UIButton *directionsButton = [UIButton buttonWithType:UIButtonTypeCustom];
    directionsButton.frame = CGRectMake(0, 0, 23, 23);
    [directionsButton setBackgroundImage:[UIImage imageNamed:@"directions.png"] forState:UIControlStateNormal];

    MyPin.leftCalloutAccessoryView = directionsButton;
    MyPin.rightCalloutAccessoryView = calloutButton;
    MyPin.draggable = NO;
    MyPin.highlighted = NO;
    MyPin.animatesDrop= YES;
    MyPin.canShowCallout = YES;

    return MyPin;
}

Remove all your annotation using the code

[self.mapView removeAnnotations:self.usersAnnotationArray];

And annotation once again to mapview , check button click using BOOL variable and set

MyPin.animatesDrop= YES;

in delagate method

    -(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation 
{
......
......
......
if(_IsButtonClikced)
{
    MyPin.animatesDrop= YES;

}
else
{
    MyPin.animatesDrop= NO;

}

................
.......
.....
}

"Hard Ball" approach would be to establish a boolean property that is set to false in viewWillAppear, but set to true in your button's action. set MyPin.animatesDrop to the property in viewForAnnotation. Don't know of any "elegant" solution.
