長按刪除谷歌地圖GMSMarker

Question

我很新的谷歌地圖API工作。我試圖讓用戶可以通過按住標記從地圖上刪除標記。我知道谷歌地圖內置了markerTapped函數以及didLongPressOnInfoWindow，但我似乎無法找到一種方法來檢測標記本身的長按。

我想知道是否有人知道在標記本身上實現長按手勢識別器的方法？或者，如果可能有更直觀的方式從地圖中刪除標記，而不是長按標記？

在此先感謝

要移除標記

在斯威夫特3

//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
