Custom MKAnnotation Image goes back to default when I attempt to drag

问题

I've got a bunch of MKAnnotations that don't need dragging. I set this by [pin setDraggable:NO]. I'm having an issue when I touch the annotation and (accidentally) drag off an annotation, it instantly looses it's custom image and changes back to the default red pin. How do I prevent this from happening?

回答1:

In the viewForAnnotation delegate method, make sure the view is created as an MKAnnotationView and not an MKPinAnnotationView (which is a subclass of MKAnnotationView that automatically provides a pin image).
