iOS：Swift-タッチで地図にピンポイントを追加してその場所の詳細な住所を取得する方法は？

IOSマップをタッチしてアノテーションを追加し、それぞれの場所の詳細な住所（目印）を取得したい。 Swiftでこれを実現するにはどうすればよいですか？

前もって感謝します。

地図のタッチに反応するには、mapViewのタップ認識機能を設定する必要があります

viewDidLoad：

let gestureRecognizer = UITapGestureRecognizer(target: self, action:"handleTap:")
    gestureRecognizer.delegate = self
    mapView.addGestureRecognizer(gestureRecognizer)

タップを処理して、タップされた場所の座標を取得します。

func handleTap(gestureRecognizer: UILongPressGestureRecognizer) {

    let location = gestureRecognizer.locationInView(mapView)
    let coordinate = mapView.convertPoint(location, toCoordinateFromView: mapView)

    // Add annotation:
    let annotation = MKPointAnnotation()
    annotation.coordinate = coordinate
    mapView.addAnnotation(annotation)
}

これで、注釈を描画するためにMKMapViewデリゲート関数を実装するだけで済みます。単純なグーグル検索はあなたにそれの残りを得るはずです。

これは、Xcode 10.1、Swift 4.2プロジェクトMapKitデリゲート注釈（ピンの色、ピン画像など）を制御し、追加された注釈のクリックを処理する委任： Github Project

Swift 4の場合、Swift 3の例を他のSwift 4のように変換したので、私にはうまくいきませんでした：（I m他のコードに合わせるために、 'mapView'ではなく 'mapview'を使用する

        let gestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))
        gestureRecognizer.delegate = self
        mapview.addGestureRecognizer(gestureRecognizer)


@objc func handleTap(_ gestureReconizer: UILongPressGestureRecognizer)
    {

        let location = gestureReconizer.location(in: mapview)
        let coordinate = mapview.convert(location,toCoordinateFrom: mapview)

        // Add annotation:
        let annotation = MKPointAnnotation()
        annotation.coordinate = coordinate
        mapview.addAnnotation(annotation)
    }

For Swift 3.の場合

let gestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))
gestureRecognizer.delegate = self
mapView.addGestureRecognizer(gestureRecognizer)

func handleTap(_ gestureReconizer: UILongPressGestureRecognizer) {

    let location = gestureReconizer.locationInView(mapView)
    let coordinate = mapView.convertPoint(location,toCoordinateFromView: mapView)

    // Add annotation:
    let annotation = MKPointAnnotation()
    annotation.coordinate = coordinate
    mapView.addAnnotation(annotation)
}

他の回答はタッチイベントの処理方法を適切にカバーしているため、次のステップはCLGeocoderを使用して逆ジオコーディングを実行し、位置の値をその位置の目印のリストに変換します。

func handleTap(gestureReconizer: UILongPressGestureRecognizer) {

    let location = gestureReconizer.locationInView(mapView)
    let coordinate = mapView.convertPoint(location,toCoordinateFromView: mapView)

    let geocoder = CLGeocoder()
    geocoder.reverseGeocodeLocation(coordinate) { (placemarks, error) in 
        if let places = placemarks {
            for place in places {
                print("found placemark \(place.name) at address \(place.postalAddress)"
            }
        }
    }
}
