iphone - 如何从以下方法获取新位置

Question

-(void)mapView:(MKMapView *)mapView 
    annotationView:(MKAnnotationView *)view                  
    didChangeDragState:(MKAnnotationViewDragState)newState 
    fromOldState:(MKAnnotationViewDragState)oldState

Answer 1

你使用这个:

- (void)mapView:(MKMapView *)mapView 
        annotationView:(MKAnnotationView *)annotationView 
        didChangeDragState:(MKAnnotationViewDragState)newState 
        fromOldState:(MKAnnotationViewDragState)oldState 
{
    if (newState == MKAnnotationViewDragStateEnding)
    {
        CLLocationCoordinate2D droppedAt = annotationView.annotation.coordinate;
        NSLog(@"dropped at %f,%f", droppedAt.latitude, droppedAt.longitude);
    }
}

当 MKAnnotationView 被放下时，这将为您提供最终位置的坐标。
