ios – Swift后台使用Core Location获取位置更新

import CoreLOCATIOn

class ViewController: UIViewController,UITextFieldDelegate,CLLOCATIOnManagerDelegate  {

   var LOCATIOnManager:CLLOCATIOnManager = CLLOCATIOnManager()



    override func viewDidLoad() {
        super.viewDidLoad()


        self.LOCATIOnManager.delegate = self
        LOCATIOnManager.desiredAccuracy = kCLLOCATIOnAccuracyBest
        LOCATIOnManager.requestAlwaysAuthorization()
        LOCATIOnManager.startupdatingLOCATIOn()


        }

    func LOCATIOnManager(manager: CLLOCATIOnManager,didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        print("didChangeAuthorizationStatus")

        switch status {
        case .NotDetermined:
            print(".NotDetermined")
            break

        case .Authorized:
            print(".Authorized")
            self.LOCATIOnManager.startupdatingLOCATIOn()
            break

        case .Denied:
            print(".Denied")
            break

        default:
            print("Unhandled authorization status")
            break

        }
    }

   func LOCATIOnManager(manager: CLLOCATIOnManager,didupdateLOCATIOns LOCATIOns: [CLLOCATIOn]) {

        let LOCATIOn = LOCATIOns.last as CLLOCATIOn!

        print("didupdateLOCATIOns:  \(LOCATIOn.coordinate.latitudE),\(LOCATIOn.coordinate.longitudE)")


    }

仅提供输出

didChangeAuthorizationStatus
.NotDetermined

如果有可能我想在新位置改变时采用长拉特值.
谢谢 ！
