如何在 swift 中使用 CLLocationManager 获取位置用户？

我的视图控制器上有这段代码，但这不起作用：

  import UIKit
  import CoreLocation

  class ViewController: UIViewController, CLLocationManagerDelegate {

   var location: CLLocationManager!

  override func viewDidLoad() {
     super.viewDidLoad()

     location=CLLocationManager()
     location.delegate = self
     location.desiredAccuracy=kCLLocationAccuracyBest
     location.startUpdatingLocation()
 }

  func locationManager(location:CLLocationManager, didUpdateLocations locations:AnyObject[]) {
     println("locations = \(locations)")
     label1.text = "success"
 }

我拥有我在其他帖子中阅读的权限。但我没有得到，没有 println ..

Thanks!!

首先在 plist 文件中添加这两行

1) NSLocationWhenInUseUsageDescription

2) NSLocationAlwaysUsageDescription

那么这就是类工作的完整实现

import UIKit 
import CoreLocation

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {

var window: UIWindow?
var locationManager: CLLocationManager!
var seenError : Bool = false
var locationFixAchieved : Bool = false
var locationStatus : NSString = "Not Started"

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    initLocationManager();
    return true
}

// Location Manager helper stuff
func initLocationManager() {
    seenError = false
    locationFixAchieved = false
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.locationServicesEnabled
    locationManager.desiredAccuracy = kCLLocationAccuracyBest

    locationManager.requestAlwaysAuthorization()
}

// Location Manager Delegate stuff

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
    locationManager.stopUpdatingLocation()
    if (error) {
        if (seenError == false) {
            seenError = true
           print(error)
        }
    }
}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: AnyObject[]!) {
    if (locationFixAchieved == false) {
        locationFixAchieved = true
        var locationArray = locations as NSArray
        var locationObj = locationArray.lastObject as CLLocation
        var coord = locationObj.coordinate

        println(coord.latitude)
        println(coord.longitude)
    }
}

func locationManager(manager: CLLocationManager!,
    didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        var shouldIAllow = false

        switch status {
        case CLAuthorizationStatus.Restricted:
            locationStatus = "Restricted Access to location"
        case CLAuthorizationStatus.Denied:
            locationStatus = "User denied access to location"
        case CLAuthorizationStatus.NotDetermined:
            locationStatus = "Status not determined"
        default:
            locationStatus = "Allowed to location Access"
            shouldIAllow = true
        }
        NSNotificationCenter.defaultCenter().postNotificationName("LabelHasbeenUpdated", object: nil)
        if (shouldIAllow == true) {
            NSLog("Location to Allowed")
            // Start location services
            locationManager.startUpdatingLocation()
        } else {
            NSLog("Denied access: \(locationStatus)")
        }
}
}
