带有 Swift 的 Mapkit Pin 注释

Question

我正在尝试显示带有多个图钉的世界地图。当点击左按钮时，它应该执行一个 phone 调用，每个 pin 与不同的 phone 号码相关联。我四处搜索并提出了以下代码，但它调用了相同的号码。如何为每个引脚注释分配特定的 phone 编号？

import MapKit
import CoreLocation



class CrewDesksViewController: UIViewController, MKMapViewDelegate {

    @IBOutlet weak var mapView: MKMapView!

    @IBOutlet weak var callCrew: UISegmentedControl!


  let locationManager = CLLocationManager()


    override func viewDidLoad() {
        super.viewDidLoad()



        // Ask for Authorisation from the User.
        self.locationManager.requestAlwaysAuthorization()

        // For use in foreground
        self.locationManager.requestWhenInUseAuthorization()

        if CLLocationManager.locationServicesEnabled() {
//            locationManager.delegate = self
            locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
            locationManager.startUpdatingLocation()

        }
        //Setup our Map View



        self.mapView.delegate = self


        mapView.showsUserLocation = true


    // pin location of different phone numbers for contacting the crewdesk

Answer 1

您正在使用 class PinAnnotation，但没有向我们提供 class 的定义。

我假设它是一些 object 符合 MKAnnotation 协议的。

您正在将 phone 数字保存在 PinAnnotation object 的副标题属性中。

在您的 calloutAccessoryControlTapped 方法中，您获取传递给用户点击的注释视图。

MKAnnotationView class 有一个属性注释，其中包含与注释视图关联的注释 object。

您需要从注释视图中获取注释，加载副标题属性（这是 MKAnnotation 协议的一部分）并将其用作 phone 编号来放置您的 phone 呼叫.

Answer 2

这是引脚注释class。我明白你在说什么，但我对编码还太陌生，无法将你的观察结果转化为代码。

import Foundation
import UIKit
import MapKit

class PinAnnotation : NSObject, MKAnnotation {
    private var coord: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 0, longitude: 0)

    var coordinate: CLLocationCoordinate2D {
        get {
            return coord
        }
    }

    var title: String = ""
    var subtitle: String = ""

    func setCoordinate(newCoordinate: CLLocationCoordinate2D) {
        self.coord = newCoordinate
    }
}
