使用CoreLocation时找错位置时出错

Question

我试图使用XCode 7.1＆amp ;;来抓住用户的位置。适用于iOS 9.1。

我没有在代码中看到任何错误，但每次尝试获取位置时我都会遇到同样的错误。 Error finding location: The operation couldn’t be completed. (kCLErrorDomain error 0.)

这是我的代码：

import UIKit
import AVFoundation
import CoreLocation

class secondview: UIViewController, CLLocationManagerDelegate {
    var player = AVPlayer() // Audio Player
    let locationManager = CLLocationManager() // Location Manager


    override func viewDidLoad() {
        super.viewDidLoad()
        //PlayEntryAudio() // Start playing entry audio
        locationManager.requestWhenInUseAuthorization()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
        locationManager.requestLocation()
    }

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.first {
            print("Current location: \(location)")
        } else {
            // ...
        }
    }

    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
        print("Error finding location: \(error.localizedDescription)")
    }



    func PlayEntryAudio(){
        print("Got here")
        let url = NSURL(string: "https://9147abb4.ngrok.io/track.mp4")!
        let playerItem = AVPlayerItem( URL:url)
        player = AVPlayer(playerItem:playerItem)
        player.play()
    }

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


}

编辑01：注意到我没有收到警告要求我获取位置，所以我尝试添加locationManager.requestWhenInUseAuthorization()但没有成功。
