Swift 5：如何在tap/touch上的GoogleMap上添加带坐标的Marker？

Question

我正在为 iOS 学习 GoogleMap-SDK，在此过程中我确实搜索了上述问题并找到了令人满意的答案，但没有找到实际有用的答案。

: Swift 3 google map add markers on touch

它添加了标记但没有地名或地点详细信息，没有该标记就没有那么有用，为此我必须搜索其他答案以从坐标中获取地址。

所以，我在这里合并了两个答案，以节省开发人员的时间并使其标记更实用。

为Swift5.0+

First, make sure you have added GMSMapViewDelegate delegate to your ViewController Class

我们不需要 UILongPressGestureRecognizer 或 UITapGestureRecognizer，GMSMapViewDelegate 为此提供了方便的默认方法。

///This default function fetches the coordinates on long-press on `GoogleMapView`
func mapView(_ mapView: GMSMapView, didLongPressAt coordinate: CLLocationCoordinate2D) {
     
     //Creating Marker
     let marker = GMSMarker(position: coordinate)
    
     let decoder = CLGeocoder()

     //This method is used to get location details from coordinates
     decoder.reverseGeocodeLocation(CLLocation(latitude: coordinate.latitude, longitude: coordinate.longitude)) { placemarks, err in
        if let placeMark = placemarks?.first {

            let placeName = placeMark.name ?? placeMark.subThoroughfare ?? placeMark.thoroughfare!   ///Title of Marker
            //Formatting for Marker Snippet/Subtitle       
            var address : String! = ""
            if let subLocality = placeMark.subLocality ?? placeMark.name {
                address.append(subLocality)
                address.append(", ")
            }
            if let city = placeMark.locality ?? placeMark.subAdministrativeArea {
                address.append(city)
                address.append(", ")
            }
            if let state = placeMark.administrativeArea, let country = placeMark.country {
                address.append(state)
                address.append(", ")
                address.append(country)
            }

            // Adding Marker Details
            marker.title = placeName
            marker.snippet = address
            marker.appearAnimation = .pop
            marker.map = mapView
        }
    }
}

希望对您有所帮助！！！
