I have a MKMapView with grouping (annotations are grouped based on zoom) and I want to do some animation when I change from group to single annotations.
I've tried to use UIView.Animate but it doesn't work and trying to find alternative ways (just change opacity) I have:
mapView.AddAnnotation (toPlaceAnnotation); MKAnnotationView annotationView = mapView.ViewForAnnotation (toPlaceAnnotation); annotationView.Alpha = 0.5f; annotationView.Opaque = false;
But annotationView is null, why? How I can I do an animation after placing an annotation?
