更改 google 映射 Poitum 标记

Question

我正在构建一个 iOS 应用程序，我想在其中更改默认的红色 google 地图标记，不幸的是，我试图在整个互联网上查找，但找不到任何解决方案。我的问题是我已经使用 gmaps utils 实现了 gmaps 集群，但我似乎无法找到更改 class POIItem 项目图标的方法。当尝试更改制造商外观时，会显示默认和自定义的两个标记。

所以这是一个代码片段： func getClubs(){

        ref.child("Clubs").observe(.value, with: { (snapshot) in
            for child in snapshot.children{
                let snap = child as! DataSnapshot
                let value = snap.value as? [String: Any]
                //print(value!)
                let name = value?["Name"] as? String
                //let latitude = value?["Latitude"] as? String
                //let longitude = value?["Longitude"] as? String
                let contact = value?["Contact"] as? String
                let prix = value?["Prix"] as? [String:Int]

                var adresse = value?["Adresse"] as? String
                if adresse == nil {
                    adresse = value?["Address"] as? String
                }
                var idFB = value?["ID Facebook"] as? Int
                if idFB == nil {
                    idFB = value?["Facebook ID"] as? Int
                }

                //let clubFbId = String(describing: idFB)
                //print(clubFbId)
                print("\(idFB)")

                let clubStruct: Club = Club(name: name!, adresse: adresse!, contact: contact!, clubIdFb: idFB!)

                if prix != nil {
                    clubStruct.prix = prix
                }

                self.clubArray.updateValue(clubStruct, forKey: idFB!)
                print(self.clubArray[idFB!]?.name)
            }
        }){ (error) in
            print(error.localizedDescription)
        }

        ref.child("Events").observe(.value, with: { (snapshot) in
            //var indice: Int = 1
            for child in snapshot.children{
                let snap = child as! DataSnapshot
                //print(snap.key)
                let event = snap.childSnapshot(forPath: "0").value as? [String:Any]
                let place = snap.childSnapshot(forPath: "0").childSnapshot(forPath: "place").value as? [String:Any]

                let clubFbId = place?["id"] as? String

                let name = event?["name"] as? String
                let start_time = event?["start_time"] as? String
                let end_time = event?["end_time"] as? String
                let eventFbId = event?["id"] as? String
                let videoURL = event?["videoURL"] as? String
                let timetable = event?["timetable"] as? [String:String]

                let dateFormatter = DateFormatter()
                dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
                dateFormatter.timeZone = TimeZone(abbreviation: "GMT+2:00")

                let start = dateFormatter.date(from: start_time!)!
                let end = dateFormatter.date(from: end_time!)!

                if self.currentDate! > end {
                    continue
                }

                let location = snap.childSnapshot(forPath: "0").childSnapshot(forPath: "place").childSnapshot(forPath: "location").value as? [String:Any]

                let latitude = location?["latitude"] as? CLLocationDegrees
                let longitude = location?["longitude"] as? CLLocationDegrees

                let eventStruct: Event = Event(latitude: latitude!, longitude: longitude!, clubIdFb: clubFbId!, eventIdFb: Int(eventFbId!)!, name: name!, start: start, end: end, idFirebase: snap.key)

                if videoURL != nil {
                    eventStruct.videoURL = videoURL
                }

                if timetable != nil {
                    eventStruct.timetable = timetable
                }

                self.eventArray.updateValue(eventStruct, forKey: clubFbId!)
                //print(self.eventArray[clubFbId!]?.name)


                let event_marker = GMSMarker()
                let clubimage = UIImage(named: "clubmarker")
                let markerView = UIImageView(image: clubimage)
                markerView.frame = CGRect(x: 0, y: 0, width: 58, height: 103)
                event_marker.position = CLLocationCoordinate2D(latitude: latitude!, longitude: longitude!)




                event_marker.map = mapViewFirst
                event_marker.iconView = markerView
                event_marker.isTappable = true
                event_marker.groundAnchor = CGPoint(x: 0.5, y: 0.5)
                let position = CLLocationCoordinate2D(latitude: latitude!, longitude: longitude!)
                let event_item = POIItem(position:position, marker: event_marker)
                self.clusterManager.add(event_item)
                self.clusterManager.cluster()
                //      var iconGenerator : GMUDefaultClusterIconGenerator!
                //      let renderer = GMUDefaultClusterRenderer(mapView: mapViewFirst, clusterIconGenerator: iconGenerator)

                if event_marker.position.latitude == self.latitude{
                    event_marker.iconView?.tintColor = UIColor.red
                }

            }
        }){ (error) in
            print(error.localizedDescription)
        }

    }
    print(eventArray)

    getClubs()

如果有人有解决方案，我将不胜感激我对编程还很陌生，而且我已经坚持了一段时间了。

Answer 1

这是 Google 文档 link：Customizing Marker Clusters

所以在 SWIFT 中回答：它不漂亮但很有效。

对于其他基本标记：

Google 中基本标记的文档是 link： change the marker color

marker.icon = GMSMarker.markerImage(with: .black)
