iPhone MapKit: Accessibility of Annotations

does anybody know how it is possible to add an accessibility label to a map annotation? I've tried adding it to the MKAnnotationView and the MKAnnotation but neither works. VoiceOver always only reads "pin" when an annotation is开发者_如何学运维 selected, while the original Maps application features the correct title when selecting an annotation.

Thanks and best regards,

Chris

In your -mapView:viewForAnnotation: set the accessibilityValue of your returned MKAnnotationView object.
