我的简单地图项目没有在模拟器中显示和显示我的位置

Question

我正在使用XCode v7.2.1,Simulator v9.2.

我有一个UIViewController,它显示一个地图并且应该获取我的位置并在地图上显示:

import UIKit
import MapKit

class LocationVC: UIViewController, MKMapViewDelegate {
    @IBOutlet weak var map: MKMapView!

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        map.delegate = self
    }

    override func viewDidAppear(animated: Bool) {
        if CLLocationManager.authorizationStatus() == .AuthorizedWhenInUse {
            map.showsUserLocation = true
        } else {
            locationManager.requestWhenInUseAuthorization()
        }
    }

}

我NSLocationWhenInUseUsageDescription在info.plist中添加了如下所示:

我还选择了调试 - >位置 - >自定义位置...并设置芬兰赫尔辛基的经度和纬度,如下所示:

当我运行我的应用程序时,会显示地图,但它不会获取我的位置.为什么？(我的意思是我没有在地图的任何地方看到蓝点).

===== UPDATE ====

我的应用程序运行时也尝试了这个,但它也没有用.

您正在请求用户的位置,但实际上没有对响应做任何事情.成为位置经理的代表并回应授权变更.

这段代码适用于7.2.1(在Debug - > Location中选择"Apple"之后):

import UIKit
import MapKit

class ViewController: UIViewController, CLLocationManagerDelegate {
    @IBOutlet weak var map: MKMapView!

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        locationManager.delegate = self
    }

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        if CLLocationManager.authorizationStatus() == .AuthorizedWhenInUse {
            map.showsUserLocation = true
        } else {
            locationManager.requestWhenInUseAuthorization()
        }
    }

    func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        guard status == .AuthorizedWhenInUse else { print("not enabled"); return }
        map.showsUserLocation = true
    }
}
