如何在GMSMapView上实现GMSMarker拖放功能？ [英] How to implement GMSMarker drag drop on GMSMapView?

问题描述

1. 我在google地图上设置了标记，但是当我拖动它时，所有的地图都被拖动。

1. I set the marker on google map but when i drag it's all of map are drag.

当点击并拖动它的

并拖动地图，点击并拖动到标记之外时，需要拖动标记。

and drag map when click and drag outside marker.

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];

这是拖放事件

- (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和调试所有上述事件不工作。
但事件点击标记工作很好。

when i run my app and debug all above event not work. but event click on marker work well.

我如何实现拖放？

推荐答案

您必须先按住标记才能开始拖动。我以为这是没有工作，直到有人指出这一点，真的需要在Google的文档中。

You have to press-and-hold on the marker before it will begin dragging. I thought it wasn't working either until someone pointed this out... really needs to be in Google's documentation.
