ios - CoreLocation requestWhenInUseAuthorization() 在 Swift 中不起作用

Question

我希望我的应用显示用户的位置，但它不要求 WhenInUseAuthorization。我在 Info.plist 中添加了 NSLocationWhenInUseUsageDescription 键。我在具有模拟位置的 iOS 模拟器中以及在实际设备上进行了尝试。

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

    @IBOutlet weak var mapView: MKMapView!

    var locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest

        if CLLocationManager.authorizationStatus() == .NotDetermined {
            self.locationManager.requestWhenInUseAuthorization()
        }
    }

    func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {

        if CLLocationManager.authorizationStatus() == .AuthorizedWhenInUse {
            locationManager.startUpdatingLocation()
            mapView.showsUserLocation = true

            let userLocation = CLLocationCoordinate2DMake(locationManager.location.coordinate.latitude, locationManager.location.coordinate.longitude)
            mapView.region = MKCoordinateRegionMakeWithDistance(userLocation, 100, 100)

        } else {

            let defaultLocation = CLLocationCoordinate2DMake(45.5017, -73.5673)
            mapView.region = MKCoordinateRegionMakeWithDistance(defaultLocation, 100, 100)
        }
    }
}

这是我的错误，我在测试文件夹的 Info.plist 而不是主项目的 plist 中添加了 NSLocationWhenInUseUsageDescription 键。
