Implement the didAddAnnotationViews delegate method and do the animation yourself:

- (void)mapView:(MKMapView *)mapView 
          didAddAnnotationViews:(NSArray *)annotationViews
{
    for (MKAnnotationView *annView in annotationViews)
    {
        CGRect endFrame = annView.frame;
        annView.frame = CGRectOffset(endFrame, 0, -500);
        [UIView animateWithDuration:0.5 
                animations:^{ annView.frame = endFrame; }];
    }
}
