デフォルトの緯度と経度を設定し、現在の場所を取得してそれを使用しようとすると、それが機能することについての私の最初の質問です。また、私はこれに従って ユーザーの現在の場所/座標を取得しましたが、結果に到達できませんでした。

ここで何が起こっているのかわからない うまくいかない いくつかの方法で試してみてください

   func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

            //print(locations)
            //get the actual location from the device and first one each move
            let userClLocation : CLLocation = locations[0]

            let latitude = userClLocation.coordinate.latitude
            let longitude = userClLocation.coordinate.longitude


   durationDestance(origin: "\(latitude),\(longitude)", destination: destination, mode:"auto")

    }

 func durationDestance(origin: String, destination: String, mode:String) {

            var urlString : String = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=\(origin)&destinations=\(destination)&mode=\(mode)&key=AIzaSyAVOt9LLagNGSOI8O0ri1Sbahcl_q5AFYc";

            urlString = urlString.addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed)!
            let session = URLSession.shared
            let url = URL(string:urlString)!
            session.dataTask(with: url) { (data: Data?, response: URLResponse?, erorr: Error?) -> Void in

                print("url: \(urlString)")
                if let responseData = data {
                    do{
                        let json = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments);
                        print(json);
                    }
                    catch{
                        print("do not serialization :)");
                    }
                }
                }.resume();
        }

私の目標: コードが機能しない理由がわかりません。私の主な目標は、ユーザーの現在の場所と目的地を取得して、所要時間と km を計算することです。

現在の場所を取得するための完全なサンプル

ViewController.swift

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    @IBOutlet weak var mapView: MKMapView!

    var locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        mapView.showsUserLocation = true

    }

    private func updateCurrentLocation() {
        locationManager.startUpdatingLocation()
    }

    @IBAction func showCurrentLocation(_ sender: UIBarButtonItem) {
        updateCurrentLocation()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let userLocation:CLLocation = locations[0] as CLLocation

        manager.stopUpdatingLocation()

        let coordinations = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude,longitude: userLocation.coordinate.longitude)
        let span = MKCoordinateSpanMake(0.2,0.2)
        let region = MKCoordinateRegion(center: coordinations, span: span)

        mapView.setRegion(region, animated: true)
        print("Coordinate \(userLocation.coordinate)")

    }
}

申し訳ありませんが、出発地から目的地までの道順を計算できませんでし た。戻る理由は次のとおりです

status = "ZERO_RESULTS";
