I'm working without InterfaceBuilder.
I've an instance of MKAnnotationView with setDraggable on YES,
In My MKMapView my annotation view is displayed and I can drag and drop it.
How can I execute an method when the drop action is performed? In this method I need the new coordonates of my annotation view.
Swift solution :
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, didChange newState: MKAnnotationViewDragState, fromOldState oldState: MKAnnotationViewDragState)
{
if (newState == MKAnnotationViewDragState.ending)
{
let droppedAt = view.annotation?.coordinate
print("dropped at : ", droppedAt?.latitude ?? 0.0, droppedAt?.longitude ?? 0.0);
view.setDragState(.none, animated: true)
}
if (newState == .canceling )
{
view.setDragState(.none, animated: true)
}
}
