ios – 如何在GMSMapView上实现GMSMarker拖放？

>我在谷歌地图上设置了标记,但是当我拖动它时,所有的地图都是拖动的.

这是我的代码

self.camera = [GMSCameraPosition cameraWithLatitude:-33.86 longitude:151.20 zoom:6 bearing:0 viewingAngle:0];
self.Map = [GMSMapView mapWithFrame:self.MapView.bounds camera:self.camera];
self.Map.myLocationEnabled = YES;
self.Map.delegate = self;

GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = self.camera.target;
marker.draggable = YES;
marker.title = @"Sydney";
marker.snippet = @"Australia";
marker.map = self.Map;
marker.icon = [GMSMarker markerImageWithColor:[UIColor blueColor]];
marker.appearAnimation = kGMSMarkerAnimationPop;

[self.MapView addSubview:self.Map];

这是拖拽事件

- (void) mapView:(GMSMapView *)mapView didBeginDraggingMarker:(GMSMarker *)marker
{

}

- (void) mapView:(GMSMapView *)mapView didEndDraggingMarker:(GMSMarker *)marker
{

}

- (void) mapView:(GMSMapView *)mapView didDragMarker:(GMSMarker *)marker
{

}

当我运行我的应用程序并调试所有上述事件不起作用.
但事件点击标记工作很好.

我如何实现拖放？

解决方法

您必须在标记开始拖动之前按住该标记.我认为它不起作用,直到有人指出这一点……真的需要在谷歌的文档中.
