检测 MKMapView 何时停止移动

Question

每当用户移动我的 MKMapView 时，我都会在地图上加载更多图钉。现在，我正在使用这段代码来检测他们何时拖动它：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    return YES;
}

- (void)didDragMap:(UIGestureRecognizer*)gestureRecognizer {
    if (gestureRecognizer.state == UIGestureRecognizerStateEnded){
        CLLocationCoordinate2D topLeft, bottomRight;
        topLeft = [self.mapView convertPoint:CGPointMake(0, 0) toCoordinateFromView:self.mapView];
        CGPoint pointBottomRight = CGPointMake(self.mapView.frame.size.width, self.mapView.frame.size.height);
        bottomRight = [self.mapView convertPoint:pointBottomRight toCoordinateFromView:self.mapView];

        [self loadMorePlaces:topLeft bottomRight:bottomRight];
    }
}

但是，这只会检测用户何时停止拖动。用户可以 "fling" 地图，地图在他们完成 "dragging" 后仍然可以移动。有什么办法可以找到地图停止移动的时间吗？谢谢
