到目前为止我所做的是创建一张地图.然后显示用户位置并居中,以便地图在旅行时居中(汽车等)

但是现在我想添加一个长按手势,这样如果用户输入一个引脚就会被丢弃.我一直在努力学习教程和模拟器崩溃.

我如何添加,longPressGesturerecognizer以便它在我的上面放一个别针mapView.

这是我的代码 -

import UIKit
import MapKit
import CoreLocation

class Page2: UIViewController, MKMapViewDelegate,  CLLocationManagerDelegate{

    @IBOutlet var mapView: MKMapView!
    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        self.locationManager.delegate = self
        self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
        self.locationManager.requestWhenInUseAuthorization()
        self.locationManager.startUpdatingLocation()
        //blue dot on the map
        self.mapView.showsUserLocation = true
        //tracking mode on
        self.mapView.userTrackingMode = .follow
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    // location Manager Delegate center user on map
    private …
