xcode 8 swift 3 latlong在模拟器上工作，但不在设备上

Question

我有这段代码来获取位置latlong

import Foundation
import CoreLocation

class Utilities{

 static let locationManager = CLLocationManager()

 static func InitLocator(Delegate:CLLocationManagerDelegate){

    locationManager.desiredAccuracy = kCLLocationAccuracyBest

    locationManager.delegate = Delegate

    locationManager.requestAlwaysAuthorization()

    locationManager.distanceFilter = kCLDistanceFilterNone

    locationManager.startUpdatingLocation()


 }

 static func GetLatLong() -> [String]{


    var arrLatLong:[String] = []

    if let latitude = locationManager.location?.coordinate.latitude{
        arrLatLong.append(String(latitude))
    }else{
        arrLatLong.append("")
    }

    if let longitude = locationManager.location?.coordinate.longitude{
        arrLatLong.append(String(longitude))
    }else{
        arrLatLong.append("")
    }

    return arrLatLong

  }

 }

当我在模拟器中测试或运行它时，此方法有效，但是当我在实际设备中对其进行测试时，它为我提供了空白值。 我使用Xcode 8 swift，设备是Iphone 6s IOS 9.3.1

试试看

添加locationManager.requestWhenInUseAuthorization()和info.plist
