title: Z-index of iOS MapKit user location annotation
body: <p>I need to draw the current user annotation (the blue dot) on top of all other annotations. Right now it is getting drawn underneath my other annotations and getting hidden. I'd like to adjust the z-index of this annotation view (the blue dot) and bring it to the top, does anyone know how?</p>
  
  <p><strong>Update:</strong>
  So I can now get a handle on the MKUserLocationView, but how do I bring it forward?</p>
  
  <pre><code>- (void) mapView:(MKMapView *)aMapView didAddAnnotationViews:(NSArray *)views {
      for (MKAnnotationView *view in views) {
          if ([[view annotation] isKindOfClass:[MKUserLocation class]]) {
              // How do I bring this view to the front of all other annotations?
              // [???? bringSubviewToFront:????];
          }
      }
  }
  </code></pre>
