Open Radar

 
Summary:

After a map annotation is dragged, it no longer moves with the map view and is instead locked into the current position on the UI.

Steps to Reproduce (see attached sample project):

1. Create a map view and add some custom annotations, with a custom annotation view.

2. Make sure that the annotations are draggable.

3. Drag an annotation to a different location and drop.

4. Pan/scroll the map view.

Expected Results:

The dropped annotation should move with the map, maintaining its correct position on the map.

Actual Results:

The dropped annotation does not move at all, and is fixed on-screen, even if the coordinate it was dropped to moves off-screen.

Regression:

Investigating further, it seems that allocing a new MKAnnotationView subclass in mapView:viewForAnnotation: instead of using the dequeueReusableAnnotationViewWithIdentifier: method fixes the issue. Not ideal, but it'll provide a workaround for the moment.
