CoreLocation不能在今天的扩展中工作

我似乎无法让我的CoreLocation在我的今日扩展中工作。我已经将CoreLocation框架添加到我的Today Extension中，并将必要的项目添加到plist（NSLocationAlwaysUsageDescription）并添加了一个默认位置，但它仍然不起作用。我正在尝试打印日志的纬度。CoreLocation不能在今天的扩展中工作

我是新来的iOS编程，任何帮助将不胜感激！请参见下面的代码↓↓↓

import Foundation 
import UIKit 
import NotificationCenter 
import CoreLocation 

class WidgetViewController: UIViewController, NCWidgetProviding, CLLocationManagerDelegate { 


var latitude: Double? 
var longitude: Double? 


var manager:CLLocationManager! 


override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view from its nib. 


    manager = CLLocationManager() 
    manager.delegate = self 
    manager.desiredAccuracy - kCLLocationAccuracyBest 
    manager.requestAlwaysAuthorization() 
    manager.startUpdatingLocation() 


    delay(1.0) { 
     print("\(self.latitude)") 
    } 


} 

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

func widgetPerformUpdateWithCompletionHandler(completionHandler: ((NCUpdateResult) -> Void)) { 
    // Perform any setup necessary in order to update the view. 

    // If an error is encountered, use NCUpdateResult.Failed 
    // If there's no update required, use NCUpdateResult.NoData 
    // If there's an update, use NCUpdateResult.NewData 

    completionHandler(NCUpdateResult.NewData) 
} 


// MARK: - Location Code 

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 

    print(locations) 

    //userLocation - there is no need for casting, because we are now using CLLocation object 

    var userLocation:CLLocation = locations[0] 


    latitude = (userLocation.coordinate.latitude) 

    longitude = (userLocation.coordinate.longitude) 


    CLGeocoder().reverseGeocodeLocation(userLocation, completionHandler: { (placemarks, error) -> Void in 

     if (error != nil) { 

      print(error) 

     } else { 

      if let p = placemarks?[0] { 

       var subThoroughfare:String = "" 

       if (p.subThoroughfare != nil) { 

        subThoroughfare = p.subThoroughfare! 

       } 


       print(p) 

      } 


     } 

    }) 

} 


func delay(delay: Double, closure:()->()) { 


    dispatch_after(
     dispatch_time(
      DISPATCH_TIME_NOW, 
      Int64(delay * Double(NSEC_PER_SEC)) 
     ), 
     dispatch_get_main_queue(), 
     closure 
    ) 
} 
}

您是否获得了位置权限警报？ – firstinq

是的，我确实收到该警报 – fellowProgrammer

你可以做两件事情：

检查是否正常工作在真实设备上。
或使用GPX文件，而不是在Xcode构建方案（我查了一下这个自己和它的作品）的预定位置

样品GPX文件内容模拟位置：

<gpx version="1.1" creator="Xcode"> 
    <wpt lat="47.52789018096815" lon="7.385249894876031"></wpt> 
    <wpt lat="47.52720984945248" lon="7.382647784661411"></wpt> 
</gpx>
