J'ai ce code sur mon contrôleur de vue mais cela ne fonctionne pas:
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"
}
J'ai les permisions comment je lis dans l'autre post. mais je n'obtiens jamais, pas d'impression ..
Merci!!
d'abord ajouter ces deux lignes dans le fichier plist
1) NSLocationWhenInUseUsageDescription
2) NSLocationAlwaysUsageDescription
Ensuite, ceci est un travail de classe complet
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)")
}
}
}
Voici les étapes simples à suivre pour obtenir la localisation d’utilisateur dans Swift 3.
1) Ajoutez d'abord cette ligne dans le fichier plist avec la description
NSLocationWhenInUseUsageDescription
2) Ajoutez CoreLocation.framework dans votre projet (sous la section Build Phases-> Link Binary With Library)
3) en classe AppDelegate
import CoreLocation
4) Créer un objet locationManager comme suit
var locationManager:CLLocationManager!
5) Écrire le code suivant dans didFinishLaunchingWithOptions
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.distanceFilter = 200
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
6) Confirmez le délégué CLLocationManagerDelegate comme suit
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate
7) Écrire la méthode déléguée CLLocationManagerDelegate pour obtenir l'emplacement de l'utilisateur
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("location error is = \(error.localizedDescription)")
}
func locationManager(_ manager: CLLocationManager,
didUpdateLocations locations: [CLLocation]) {
let locValue:CLLocationCoordinate2D = (manager.location?.coordinate)!
print("Current Locations = \(locValue.latitude) \(locValue.longitude)")
}
Puisque vous déclarez que l'emplacement est explicitement facultatif (CLLocationManager!), Il nécessite un initialiseur, que ce soit dans une méthode init telle que suggérée par jhurray, ou simplement inline, sous la forme:
var location: CLLocationManager! = nil
Notez que vous avez également d'autres problèmes possibles, notamment le fait qu'iOS 8 impose de nouvelles exigences pour demander à l'utilisateur l'autorisation d'utiliser CoreLocation. Voir cette question pour plus d'informations.
Il s'agit du même code que ci-dessus mais nettoyé pour fonctionner avec Swift à compter de la date de cette publication. Cela a fonctionné pour moi.
Bravo à l'affiche originale.
(notez-le dans la classe que vous utiliserez pour gérer votre matériel de localisation.)
var lastLocation = CLLocation()
var locationAuthorizationStatus:CLAuthorizationStatus!
var window: UIWindow?
var locationManager: CLLocationManager!
var seenError : Bool = false
var locationFixAchieved : Bool = false
var locationStatus : NSString = "Not Started"
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
self.initLocationManager()
}
// Location Manager helper stuff
func initLocationManager() {
seenError = false
locationFixAchieved = false
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
}
// Location Manager Delegate stuff
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
locationManager.stopUpdatingLocation()
if ((error) != nil) {
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)")
}
}
Il doit être écrit sous la forme Func locationManager (responsable: CLLocationManager, didUpdateLocations: [CLLocation]) {
Faites ce qui suit dans viewcontroller [Utiliser Swift] -
class ViewController:
UIViewController,MKMapViewDelegate,CLLocationManagerDelegate {
var locationManager: CLLocationManager?
var usersCurrentLocation:CLLocationCoordinate2D?
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager = CLLocationManager()
if CLLocationManager.authorizationStatus() == .NotDetermined{
locationManager?.requestAlwaysAuthorization()
}
locationManager?.desiredAccuracy = kCLLocationAccuracyBest
locationManager?.distanceFilter = 200
locationManager?.delegate = self
startUpdatingLocation()
usersCurrentLocation = CLLocationCoordinate2DMake(LATTITUDE, LONGITUDE)
let span = MKCoordinateSpanMake(0.005, 0.005)
let region = MKCoordinateRegionMake(usersCurrentLocation!, span)
mapview.setRegion(region, animated: true)
mapview.delegate = self
mapview.showsUserLocation = true
}
// MARK: méthodes CLLocationManagerDelegate
func startUpdatingLocation() {
self.locationManager?.startUpdatingLocation()
}
func stopUpdatingLocation() {
self.locationManager?.stopUpdatingLocation()
}
// MARK: MKMapViewDelegate
func mapView(mapView: MKMapView, didUpdateUserLocation userLocation: MKUserLocation){
mapview.centerCoordinate = userLocation.location!.coordinate
mapview.showsUserLocation = true
regionWithGeofencing()
}
Vous devez avoir des fonctions init.
Remplacez init (codeur :) et init (nibName: bundle :) et ajoutez tout init personnalisé que vous souhaitez.
Comme vous avez dit que l'emplacement n'est pas facultatif, vous devez l'initialiser avant que votre super init appelle dans TOUTES vos fonctions init.
func init() {
...
location = CLLocationManager()
// either set delegate and other stuff here or in viewDidLoad
super.init(nibName:nil, bundle:nil)
// other initialization below
}
