adding ovelay on a map(objective c)
How to add overlay on a map in objective c? (has any body tried it in iphone os 4.0)?
here is a good article on using the MKPolyline overlay to add a route type annotation to your map. It should give you an idea how to add any of the other overlays. just implement the
- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id )overlay
on your map delegate and give it the type of overlay your are drawing.
