An overlay renderer draws the visual representation of an overlay object—that is, an object that conforms to the MKOverlayMBS interface. This class defines the drawing infrastructure used by the map view. Subclasses are expected to override the drawMapRect method to draw the contents of the overlay.
The Map Kit framework provides several concrete instances of overlay renderers. Specifically, it provides renderers for each of the concrete overlay objects. You can use one of these existing renderers or define your own subclasses if you want to draw the overlay contents differently.
