【问题描述】：

我正在尝试在我的谷歌地图中创建集群。当我在地图上显示集群时，我只想显示集群计数，当单击或缩放集群时，我只想显示我的自定义标记视图。 但是标记视图在集群之前已经存在，当我放大集群时，会显示默认引脚，这是我不想要的。

下面是聚类的代码

                        for data in self.map_data 
                            //check if map data is on or off and show map data accordignly
                            let offerdata = data
                            let geocoder = CLGeocoder()
                            let strAddress = "\(offerdata.agent_street ?? "")"+" "+"\(offerdata.agent_city ?? "")"+" "+"\(offerdata.agent_zipcode ?? "")"

                            //MARK: GEOCODER FOR GETTING LAT LONG BASE ON ADDRESS
                            geocoder.geocodeAddressString(strAddress) 
                                placemarks, error in
                                let placemark = placemarks?.first
                                let lat =  Double(placemark?.location?.coordinate.latitude ?? 0.00)
                                let lon = Double(placemark?.location?.coordinate.longitude ?? 0.00)
                                print("Lat: \(String(describing: lat)), Lon: \(String(describing: lon))")

                                let camera = GMSCameraPosition.camera(withLatitude: lat, longitude: lon, zoom: 5)
                                let marker = GMSMarker()
                                marker.position = CLLocationCoordinate2D(latitude: lat, longitude: lon)
                                marker.title = "\(offerdata.agent_firstname ?? "")"+" \(offerdata.agent_lastname ?? " ")"
                                marker.iconView?.backgroundColor = .lightGray
                                marker.userData  = data

                                //amrut
                                // Clustering
                                let item = POIItem(position: CLLocationCoordinate2DMake(lat, lon), name: "marker.title" ?? "",data: data)
                                self.clusterManager.add(item)


                                //map info views
                                var image = UIImage()
                                var currency  = String()
                                if data.currency == "AUD"
                                    currency = "$\(data.currency ?? "")"
                                
                                else if data.currency == "EUR"
                                    currency = "€\(data.currency ?? "")"
                                
                                else
                                    currency = "£\(data.currency ?? "")"
                                

                                let amount = "\(data.offer_amount ?? "")".convertTo2Decimal+" "+currency

                                //create custom marker accordin to condtions
//                                    "\(agent.offer_amount ?? "")".convertTo2Decimal+" "+"\(agent.currency ?? "AUD")"
                                if data.auto_approval_on_off == "ON"
                                    if (data.is_badge_display == "1") 
                                        image = UIImage(named: "blueMarker.png") ?? UIImage()//blue
                                     else 
                                           image = UIImage(named: "orangeMarker.png") ?? UIImage()//oranfge
                                       
                                
                                 else if (data.is_badge_display == "1") 
                                    image = UIImage(named: "blueMarker.png") ?? UIImage()//blue
                                 else 
                                    image = UIImage(named: "blackMarker.png") ?? UIImage()//black
                                

                                let customMarker = CustomMarkerView(frame: CGRect(x: 0, y: 0, width: 100, height: 40), image:image , lblText:amount)
//                                    marker.iconView=customMarker

                                marker.map = self.MapView
                                self.MapView.camera = camera
                            
                        

我在 'GMUClusterRendererDelegate willRenderMarker' 委托方法中做同样的事情，只是取消注释 ma​​rker.iconView=customMarker

谁能帮我做我需要做的事情。真的很有帮助 Image for reference Image for reference2

我想要两件事： 1-显示没有地图图标视图的初始加载集群 2- 仅显示地图图标视图，而不是集群渲染/缩放后的引脚

请有人帮助我

【参考方案1】：

我有一个类似的问题。我想出的解决方法是运行 clearMarkers 函数，然后使用 addMarkers 函数重新添加整个标记数组

我还在努力，如果我找到更好的答案，我会更新

【讨论】：

当然。我会等待解决方案。如果我发现任何问题，我会发布解决方案
