长按删除谷歌地图 GMSMarker

Question

我对使用 google maps api 还是很陌生。我试图让用户选择通过按住标记从地图中删除标记。我知道谷歌地图有一个用于 markerTapped 以及 didLongPressOnInfoWindow 的内置函数，但我似乎无法找到一种方法来检测标记本身的长按。

我想知道是否有人知道在标记本身上实现长按手势识别器的方法？或者，是否有比长按标记更直观的方式从地图中删除标记？

提前致谢

移除标记​​strong>

在 Swift 3 中

//Press on Button Forcefully for long time
let pressHold = UILongPressGestureRecognizer(target: self, action: #selector(pressHolding(sender:))
self.mapView.addGestureRecognizer(pressHold)

//Handle in pressHolding Function
func pressHolding(recognizer: UILongPressGestureRecognizer)
{
    if (recognizer.state == UIGestureRecognizerState.Began)
    {
        //Here you can do your task like delete or edit on market etc:-
    }
}

//This is long Press function:-
func mapView(mapView: GMSMapView!, didLongPressAtCoordinate coordinate: CLLocationCoordinate2D) {
   //Here handle your long press on map marker like:-
   let camera = GMSCameraPosition.camera(withLatitude: -33.8683, longitude: 151.2086, zoom: 6)
   let mapView = GMSMapView.map(withFrame: .zero, camera: camera)
   mapView.clear()
}

Here you can find Objective-C and Swift All available Function of Markers
