ios - 如何在 swift 代码中更改谷歌地图中的位置箭头图标？

Question

这是我的代码，我想更改位置箭头图标(蓝点)。我如何用快速代码做到这一点。我正在使用谷歌地图!我附上了我想做的照片。

func moveCamera(marker:GMSMarker){
     map.camera = GMSCameraPosition(target: marker.position, zoom: 12, bearing: 0, viewingAngle: 0)
}

func placeMarkersInMap(){
    var marker:GMSMarker = GMSMarker()
    if(addressArray.count > 0){
        for add in addressArray{
            let position = CLLocationCoordinate2DMake(add.longitud, add.latitude)
            marker = GMSMarker(position: position)
            marker.appearAnimation = kGMSMarkerAnimationPop
            marker.icon = UIImage(named: "marker")
            marker.title = add.location
            marker.snippet = "\nTel. \(add.tel)"
            marker.infoWindowAnchor = CGPointMake(0.44, 0.45)
            marker.map = map

        }
        moveCamera(marker)
    }

}

func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    if status == .AuthorizedWhenInUse {

        locationManager.startUpdatingLocation()

        map.myLocationEnabled = true
        map.settings.myLocationButton = true

    }
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location = locations.first {

        locationManager.stopUpdatingLocation()
    }

}

let position = CLLocationCoordinate2DMake(//这里是你的坐标)

让 london = GMSMarker(position: position)

london.title = "伦敦"

london.icon = UIImage(named: "here will be your image name")

london.map = mapView;
