iOS：Swift - 如何在触摸时向地图添加精确定位并获取该位置的详细地址？

swift
import UIKit
import MapKit
class ViewController: UIViewController {
    @IBOutlet weak var mapView: MKMapView!
    override func viewDidLoad() {
        super.viewDidLoad()
        // 设置地图视图的代理
        mapView.delegate = self
    }
}

swift
override func viewDidLoad() {
    super.viewDidLoad()
    // ...
    
    // 创建一个长按手势识别器
    let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(_:)))
    longPressGesture.minimumPressDuration = 0.5 // 设置长按的最短时间
    mapView.addGestureRecognizer(longPressGesture)
}

swift
@objc func handleLongPress(_ gestureRecognizer: UILongPressGestureRecognizer) {
    if gestureRecognizer.state == .began {
        // 获取用户长按的位置
        let touchPoint = gestureRecognizer.location(in: mapView)
        let coordinate = mapView.convert(touchPoint, toCoordinateFrom: mapView)
        
        // 添加一个标注到地图上
        let annotation = MKPointAnnotation()
        annotation.coordinate = coordinate
        mapView.addAnnotation(annotation)
        
        // 获取位置的详细地址
        let location = CLLocation(latitude: coordinate.latitude, longitude: coordinate.longitude)
        CLGeocoder().reverseGeocodeLocation(location) { (placemarks, error) in
            if let error = error {
                print("Reverse geocoding failed with error: \(error.localizedDescription)")
                return
            }
            
            if let placemark = placemarks?.first {
                // 获取详细地址
                let address = "\(placemark.thoroughfare ?? ""), \(placemark.locality ?? ""), \(placemark.administrativeArea ?? ""), \(placemark.country ?? "")"
                print("Detailed address: \(address)")
            }
        }
    }
}

swift
extension ViewController: MKMapViewDelegate {
    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
        // 自定义标注视图的样式
        let annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "pin")
        annotationView.pinTintColor = .red
        return annotationView
    }
