The overlay object that is about to be displayed.
The renderer to use when presenting the specified overlay on the map.
You must implement this method and use it to provide an appropriate renderer object for your overlays. The renderer object is responsible for drawing the contents of your overlay when asked to do so by the map view. Map Kit supports many different types of standard renderer objects and you may also define your own custom renderers.
