ios - 使用 MapKit - Swift 3.0 将图钉添加到 map

Question

新程序员，试图弄清楚如何使用 MapKit。目标是创建一个 map ，用户可以使用他们的地址添加图钉。然而，就我现在所处的步骤而言，我根本无法弄清楚如何向 map 添加图钉。

如何在 map 上添加图钉？到目前为止，我一直在努力弄清楚如何使用注释。

这就是我希望得到的帮助/指导。谢谢!

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate

{
    @IBOutlet weak var bigMap: MKMapView!

    let locationManager = CLLocationManager()

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

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let location = locations.last
        let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
        let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.02, longitudeDelta: 0.02))

        self.bigMap.setRegion(region, animated: true)
        self.locationManager.stopUpdatingLocation()

    }

    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("Errors " + error.localizedDescription)
    }
}

它们在 MapKit 中被称为 annotations，您应该像这样实例化它们:

let annotation = MKPointAnnotation() 

然后在 viewDidLoad() 方法中设置坐标并将它们添加到 map 中，如下所示:

annotation.coordinate = CLLocationCoordinate2D(latitude: 11.12, longitude: 12.11)
mapView.addAnnotation(annotation)

数字是你的坐标
