Dragged Annotation views do not move with maps

I have a problem with my map after an annotation view is dragged: when I change the region panning the map, the dragged annotation remains fixed in the screen ( other annotation that have not been dragged are displayed correctly, the problem is on every annotation view that is dragged ; note that the annotation view continues to bel selectable for callout and dragging, the only problem that i can see is that it does not move when I pan Map )

I there any solution ? is this a known bug with ios 7.1 ? Or am i missing something in my code ?

If annotation is dragged then you have to set its drag state to none in its delegate method. This code solved my problem

    - (void)mapView:(MKMapView *)mapView
     annotationView:(MKAnnotationView *)annotationView
    didChangeDragState:(MKAnnotationViewDragState)newState
       fromOldState:(MKAnnotationViewDragState)oldState
{
if (newState == MKAnnotationViewDragStateEnding)
    {
     ..... your code.....
    annotationView.dragState=MKAnnotationViewDragStateNone;
    }

}

seems the code should care to do last transition to reset annotation view , this fixes the problem :

-(void)setDragState:(MKAnnotationViewDragState)dragState animated:(BOOL)animated {
    [super setDragState:dragState animated:animated];
    if (dragState==MKAnnotationViewDragStateStarting) {
        [...
    } else if (dragState==MKAnnotationViewDragStateEnding || dragState==MKAnnotationViewDragStateCanceling) {
        ...
        self.dragState = MKAnnotationViewDragStateNone;
    }
}
