CLLocation Manager en Swift para obtener la ubicación del Usuario

Primero agregue estas dos líneas en el archivo plist

1) NSLocationWhenInUseUsageDescription

2) NSLocationAlwaysUsageDescripción

Entonces esto es trabajo de clase completa implementar esto

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
// If failed
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)
    }
}

// authorization status
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)")
        }
}
}

No estoy seguro de por qué, pero parece que startUpdatingLocation no está presentando el mensaje de usuario en el simulador de iOS 7, pero cuando lo habilité manualmente funcionó como se esperaba si usaba la forma más reciente del método delegado:

var manager:CLLocationManager!

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

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

func locationManager(manager:CLLocationManager, didUpdateLocations locations:[AnyObject]) { // Updated to current array syntax [AnyObject] rather than AnyObject[]
    println("locations = \(locations)")
}

El formato que está utilizando ha sido obsoleto desde iOS 5 o 6, por lo que aparentemente no es compatible en absoluto con las capas de puente swift.

Tuvo el mismo problema. didUpdateLocations - no estaba funcionando. Ejecuta tu aplicación. Vaya a la página Configuración -> Privacidad -> Ubicación y desactive los Servicios de ubicación. didFailWithError detectará el error sobre los servicios de ubicación ausentes. Entonces enciéndelo. Desde ese momento didUpdateLocations capturará ubicaciones.

Espero que haya dos maneras.

    var locationManager: CLLocationManager = CLLocationManager()
  var initialLocation :CLLocation?
  var updatedUserLocation :CLLocation?

  override func viewDidLoad() {
    super.viewDidLoad() {

        //MapView Location
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        locationManager.requestWhenInUseAuthorization()
        locationManager.startUpdatingLocation()
        locationManager.startUpdatingHeading()
}

Implementando CLLocationManagerDelegate:

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

// This only works when user location is updated.
gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)

  }
  func locationManager(manager: CLLocationManager,
    didFailWithError error: NSError) {

//Error indicates GPS permission restricted

      gpsProviderStatusLabel.changeStatusToOff(gpsProviderStatusLabel)

//Initial Location
initialLocation = locations.first

//Getting Updated Location
updatedUserLocation = locations.last

  }

Comprobación de la autorización de CLLocationDelegate:

 func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {

//This method does real time status monitoring.

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

        case .AuthorizedAlways:
          print(".AuthorizedAlways")
          gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
          break


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

        case .AuthorizedWhenInUse:
          print(".AuthorizedWhenInUse")
          gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
          break

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

        default:
          print("Unhandled authorization status")
          break

        }
      }

Nota: changeStatusToOn o changeStatusToOff es un método UILabel Extenion que activa/desactiva el texto de la etiqueta con colores Verde/Rojo.

Aquí está mi código muy simple que funciona:

Primero agregue Core Location framework en General/Linked Frameworks and Libraries

Luego agrega lo siguiente en Info.plist:

<key>NSLocationWhenInUseUsageDescription</key>
<string>blablabla</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>blablabla</string>

Este es mi ViewController.archivo swift:

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    var locationManager:CLLocationManager!

    override func viewDidLoad() {
        super.viewDidLoad()

        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestAlwaysAuthorization()
        locationManager.startUpdatingLocation()
    }


    func locationManager(manager:CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print("locations = \(locations)")
    }

}

Para Swift 3

import UIKit
import CoreLocation

class ViewController: UIViewController,CLLocationManagerDelegate {


    var locationManager:CLLocationManager!

    override func viewDidLoad() {
        super.viewDidLoad()

        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestAlwaysAuthorization()
        locationManager.startUpdatingLocation()

        // Do any additional setup after loading the view, typically from a nib.
    }

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

    func locationManager(_ manager:CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print("locations = \(locations)")
    }


}

No olvides agregar Nslocación cuando se utiliza la descripción del uso o Descripción de Nslocationalwaysusaged en su archivo de configuración (target/Info/custom iOS target properties

Agregue la propiedad 2 a continuación en la información .plist

NSLocationWhenInUseUsageDescription : Location information is used for fraud prevention

Privacy - Location Usage Description : Location information is used for fraud prevention

Si desea actualizar la ubicación del usuario de forma predeterminada, sin hacer clic en 'Simular ubicación' cada vez, vaya a

YourProject-->Build Phases-->Link Binary with libraries-->Add corelocation.framework

La ubicación se actualiza automáticamente por defecto cuando se ejecuta la aplicación en el simulador. Probado y funciona en Swift 2 !

Esto solicitará permiso y rastreará si se le da permiso para salir con una alerta. Detiene el seguimiento al presionar el botón atrás.

Info.plist

<key>NSLocationAlwaysUsageDescription</key>
<string>Allow tracking while completing a survey</string>
