Swift 3-MKPointAnnotationカスタム画像

これは私のコードであり、赤いピンの代わりにカスタムピン（.pngファイル）を追加したいと思います。 MKPinAnnotationViewとMKAnnotationViewを使用しようとしましたが、座標、字幕、タイトルを追加できませんでした。私はiOS開発に不慣れです。

override func viewDidLoad() {
    super.viewDidLoad()
    // Handle the text field’s user input through delegate callbacks.
    commentTextField.delegate = self

    coreLocationManager.delegate = self
    //desired accuracy is the best accuracy, very accurate data for the location
    coreLocationManager.desiredAccuracy = kCLLocationAccuracyBest
    //request authorization from the user when user using my app
    coreLocationManager.requestWhenInUseAuthorization()

    coreLocationManager.startUpdatingLocation()

    dbRef = FIRDatabase.database().reference()

    struct Location {
        let title: String
        let latitude: Double
        let longitude: Double
        let subtitle: String
    }
    // Locations array
    let locations = [
        Location(title: "Dio Con Dio",    latitude: 40.590130, longitude: 23.036610,subtitle: "cafe"),
        Location(title: "Paradosiako - Panorama", latitude: 40.590102, longitude: 23.036180,subtitle: "cafe"),
        Location(title: "Veranda",     latitude: 40.607740, longitude: 23.103044,subtitle: "cafe")
    ]

    for location in locations {
        let annotation = MKPointAnnotation()

        annotation.title = location.title
        annotation.coordinate = CLLocationCoordinate2D(latitude: location.latitude, longitude: location.longitude)
        annotation.subtitle = location.subtitle

        map.addAnnotation(annotation)
    }

ビューコントローラをマップビューのデリゲートとして指定する必要があります（IBまたはプログラムでviewDidLoadで指定してから、（a）MKMapViewDelegateプロトコルに準拠していることを指定します;および（ b）実装 mapView(_:viewFor:) ：

extension ViewController: MKMapViewDelegate {
    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
        let identifier = "MyPin"

        if annotation is MKUserLocation {
            return nil
        }

        var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)

        if annotationView == nil {
            annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: identifier)
            annotationView?.canShowCallout = true
            annotationView?.image = UIImage(named: "custom_pin.png")

            // if you want a disclosure button, you'd might do something like:
            //
            // let detailButton = UIButton(type: .detailDisclosure)
            // annotationView?.rightCalloutAccessoryView = detailButton
        } else {
            annotationView?.annotation = annotation
        }

        return annotationView
    }
}

詳細については、 ロケーションおよびマッププログラミングガイド：デリゲートオブジェクトからの注釈ビューの作成 を参照してください。コードスニペットはObjective-Cにありますが、基本的なプロセスを説明しています。

最後に、私は自分でこのようにしました！

このメソッドを使用します：オプションのfunc mapView（_ mapView：MKMapView、didAddビュー：[MKAnnotationView]）

私にとっては問題なく動作します（私の環境：Xcode9.4.1およびiOS11.4.1）

例：

func mapView(_ mapView: MKMapView,
             didAdd views: [MKAnnotationView])
{
    //views[0] = just added MKAnnotationView
    let pic = UIImage(named: "abc.jpg")

    views[0].image = pic
    views[0].layer.cornerRadius = (views[0].frame.size.width) / 2
    views[0].clipsToBounds = true

    print("fafafjejowfjpeawijoefaw")
}

このように追加しました

    func mapView(_ mapView: MKMapView, didAdd views: [MKAnnotationView]) {
      let sourceView = views.first
      sourceView?.image = UIImage(named: "Bus")
      let destinationView = views.last
      destinationView?.image = UIImage(named: "Home")
   }
