如何使用GoogleMaps for iOS中的自定义标记进行标记聚类？

我是iOS开发的初学者。我在我的应用程序中添加了GoogleMaps，我可以将GoogleMaps的默认标记聚类，但是当我通过计算机中的图像定制标记时，自定义标记无法聚类。有人可以帮我在Swift 3中做到这一点吗？如何使用GoogleMaps for iOS中的自定义标记进行标记聚类？

我告诉你我的代码的一部分：

override func viewDidLoad() { 

mapView = GMSMapView(frame: view.frame) 
mapView.camera = GMSCameraPosition.camera(withLatitude: 48.898902, longitude: 2.282664, zoom: 12.0) 
mapView.mapType = .normal 
mapView.delegate = self 
view.addSubview(mapView) 

if isClustering { 
    var iconGenerator: GMUDefaultClusterIconGenerator! 
    if isCustom { // Here's my image if the event are clustered 
     var images: [UIImage] = [UIImage(named: "m1.png")!, UIImage(named: "m2.png")!, UIImage(named: "m3.png")!, UIImage(named: "m4.png")!, UIImage(named: "m5.png")!] 
     iconGenerator = GMUDefaultClusterIconGenerator(buckets: [10, 20, 50, 100, 200], backgroundImages: images) 
    } else { 
     iconGenerator = GMUDefaultClusterIconGenerator() 
    } 

    let algorithm = GMUNonHierarchicalDistanceBasedAlgorithm() 
    let renderer = GMUDefaultClusterRenderer(mapView: mapView, clusterIconGenerator: iconGenerator) 

    clusterManager = GMUClusterManager(map: mapView, algorithm: algorithm, renderer: renderer) 
    clusterManager.cluster() 
    clusterManager.setDelegate(self, mapDelegate: self) 
} else { 
} 

// Here's my first custom markers (I don't write here others for simple code) 
let firstLocation = CLLocationCoordinate2DMake(48.898902, 2.282664) 
let marker = GMSMarker(position: firstLocation) 
marker.icon = UIImage(named: "pointeurx1") //Apply custom marker 
marker.map = mapView 
} 

func clusterManager() {...}
