MKMapView removeAnnotation is not removing the selected annotation

问题

When I call removeAnnotation and pass it a pointer to the annotation I had added, it is not removing the annotation... Is this because it had made a copy of the annotation when I added it?

Thanks Deshawn

You could try this

nsarray *oldAnnotations=[self.mapview annotations];
[self.mapview removeAnnotations:oldAnnotations];
