如何在 GoogleMapView iOS Swift4 上显示来自 Web Api 的地址数组

Question

我正在尝试获取一组来自 webApi 的地址并将它们加载到 googleMapView 上。首先，我必须将地址转换为坐标，然后我才这样做。所以我不知道我在做什么..我正在获取数据并且我正在使用模型类...我可能做错了...

作为 iOS 开发人员，我是初学者... 有人请指导我完成这个...

代码在这里：

import GoogleMaps
import GooglePlaces
import Alamofire

class HomeViewController: UIViewController,UICollectionViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout,GMSMapViewDelegate,CLLocationManagerDelegate {

   var JSONData = [LocationData]()
   var serviceNames = [ServiceName]()

  override func viewDidLoad() {
            super.viewDidLoad()

       self.getProfessionalLocations()
}

 func getProfessionalLocations() {

        let url = "http://domailname.com/api/UsersAPI/GetLocationUsers"

        let parameters: NSDictionary = ["Address":""]

        Alamofire.request(url, method: .post, parameters: parameters as? [String:Any], encoding: JSONEncoding.default, headers: nil).responseJSON {
            response in
            switch response.result {
            case .success:
                print(response)

                self.proResponseArray = response.result.value as! NSArray

                for eachValue in self.proResponseArray {

                    let dataValue = eachValue as! [String : Any]
                    let professionalName = dataValue["userName"] as! String
                    let imagePath = "http://domailname.com/app/Users/ProfilePics/\(dataValue["profilePic"]!))"
                    let escapedAddress = imagePath.addingPercentEncoding(
                        withAllowedCharacters: CharacterSet.urlQueryAllowed)
//                    self.infoWindow.profile_Img.image = UIImage(url: URL(string: escapedAddress!))

// here I am getting the address from the api
                    let address = dataValue["searchAddress"] as! String

                    let services = dataValue["lstServiceProviders"] as! NSArray

                    for allServiceNames in services {

                        let names = allServiceNames as! [String : Any]
                        let serviceName = names["serviceName"] as! String

                        self.serviceNames.append(ServiceName(serviceName: serviceName))
                    }

                    let experience = dataValue["experience"] as! String

                    let rating = dataValue["rating"] as Any

                    self.JSONData.append(LocationData(serviceNames: self.serviceNames, proName: professionalName, proImage:  escapedAddress!, address: address, experience: experience, rating: rating))
                }

                for location in self.JSONData {

                    let marker = GMSMarker()
                    let geoCoder = CLGeocoder()
                    geoCoder.geocodeAddressString(location.address ) { (placemarks, error) in
                        guard
                            let placemarks = placemarks,
                            let addressLocation = placemarks.first?.location
                            else {
                                // handle no location found
                                return
                        }

                        marker.position = CLLocationCoordinate2DMake(addressLocation.coordinate.latitude, addressLocation.coordinate.longitude)
                        marker.icon = UIImage(named:"beautycare")!
                        self.googleMapView.camera = GMSCameraPosition.camera(withLatitude:addressLocation.coordinate.latitude, longitude: addressLocation.coordinate.longitude, zoom: self.currentZoom)
                        marker.appearAnimation = GMSMarkerAnimation.pop
                        marker.map = self.googleMapView
                    }
                }

                break
            case .failure(let error):

                print(error)
            }
        }
    }
class ServiceName {

    var serviceName : String

    init(serviceName : String) {

        self.serviceName = serviceName
    }
}

class LocationData {

    var serviceNames : [ServiceName]
    var proName : String
    var proImage : String
    var address : String
    var experience : String
    var rating: Any

    init(serviceNames:[ServiceName], proName: String, proImage: String, address : String, experience: String, rating: Any) {

        self.serviceNames = serviceNames
        self.proName = proName
        self.proImage = proImage
        self.address = address
        self.experience = experience
        self.rating = rating
    }
}

检查我下面的代码，您需要从所有 lat/long 获取所有地址。触发完成处理程序一旦收集到所有地址。

创建获取地址列表函数

typealias CompletionHandlerButton = (_ response:NSMutableArray) -> Void
func AllLocationDetected(lotLongArray: NSMutableArray,handler: @escaping CompletionHandlerButton)
{
    //Write your logic here to Get address from the Lat/long and also need to check all address list collected or not.
    handler(ListOfAddress) //Send back your List of address here
}

启动获取所有地址列表功能

AllLocationDetected { (LocationArray) in

    print(LocationArray)

}

希望对您有所帮助！
