I have a MKPinAnnotationView that the user can drag around the map.

It is very difficult for a user to drag the pin. I've tried increasing the frame size and also using a giant custom image. But nothing seems to actually change the hit area for the drag to be larger than default.

Consequently, I have to attempt to tap/drag about ten times before anything happens.

MKPinAnnotationView *annView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"bluedot"] autorelease];

UIImage *image = [UIImage imageNamed:@"blue_dot.png"];

annView.image = image;
annView.draggable = YES;
annView.selected = YES;
return annView;

What am I missing here?
