title: Add image behind MKPinAnnotationView
body: <p>I'm trying to add an image behind a MKPinAnnotationView. Seems like it should be rather easy to just do this in here:</p>
  
  <pre><code>- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views {
   for (MKAnnotationView *aView in views)
    [[aView superview] addSubview:imageView];
  }
  </code></pre>
  
  <p>But the problem I am having in doing that is that the child subview to the pin will render on top of it not BEHIND it.</p>
  
  <p>I have also tried:</p>
  
  <pre><code> for (MKAnnotationView *aView in views)
    [[aView superview] insertSubview:imageView atIndex:1];
  </code></pre>
  
  <p>The problem with this is that, while it IS behind the pin, as soon as the map is repositioned, the image floats off the screen.</p>
  
  <p>Any suggestions? Thanks</p>
