ios - 如何在多个标记之间绘制折线？

Question

想要从 userLocation 到多个标记绘制折线。在我的代码中，已经在数组中添加了标记坐标，然后将 userLocation 添加到该数组的第 0 个位置。现在我想在数组元素之间绘制一条路径折线。我的代码如下...

self.coods.append(self.currentLocation)

                let jsonResponse = response.data
                do{

                    let json = try JSON(data: jsonResponse!)
                    self.dictXYZ = [json]
                    print("JsonResponse printed \(json["data"][0]["lattitude"])")
                    if let array = json["data"].array{
                        for i in 0..<array.count{
                        var coordinate = CLLocationCoordinate2D()
                            coordinate.latitude = array[i]["lattitude"].doubleValue
                            coordinate.longitude = array[i]["longitude"].doubleValue

                            self.coods.append(coordinate)
                        }

                        for j in self.coods {

                            let marker = GMSMarker()

                            marker.position = j
                            let camera = GMSCameraPosition.camera(withLatitude: j.latitude, longitude: j.longitude, zoom: 12)

                            self.mapView.camera = camera
                            marker.map = self.mapView
                        }

let path = GMSMutablePath()
for j in self.coods {
path.add(j)
}
let polyline = GMSPolyline(path: path)
polyline.map = mapView
