get user location and updates - ios

I am trying to get user location in my iPhone app. It has specified in info.plist needed permission (use location even if app is not offline). But still I do not see that my delegate is triggered at least once meaning I do not get even current location. Here is the code:
import UIKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
var locationManager = CLLocationManager();
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager.delegate = self
if (CLLocationManager.authorizationStatus() == CLAuthorizationStatus.notDetermined) {
self.locationManager.requestAlwaysAuthorization();
}
locationManager.distanceFilter = kCLDistanceFilterNone
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation:CLLocation = locations[0]
let long = userLocation.coordinate.longitude;
let lat = userLocation.coordinate.latitude;
print(lat)
}
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!)
{
locationManager.stopUpdatingLocation()
if ((error) != nil)
{
print(error)
}
}
Could somebody point me out possible problems?

Try to remove locationManager.stopUpdatingLocation() in locationManager(manager: CLLocationManager!, didFailWithError error: NSError!). It should work.

CLLocationManager delegate methods are not getting called(google maps is integrated)

The delegate Methods of CLLocationManager
didChangeAuthorizationStatus
and
didUpdateToLocation
are not getting called.
Location Always Usage Description key is already added in info.plist and I am getting notification also when i launch app for the first time.
I am able to see the google map, but i am not able to see current location, When i change location, its not getting updated. Basicaaly delegate methods are not getting called.
//code
import UIKit
import GoogleMaps
class ViewController: UIViewController,GMSMapViewDelegate {
#IBOutlet weak var mapViewTest: GMSMapView!
let locationManager = CLLocationManager()
var currentLocation :CLLocation = CLLocation(latitude: 0.0, longitude: 0.0)
var currentLatitude : Double = 0.0
var currentLongitude : Double = 0.0
override func viewDidLoad()
{
super.viewDidLoad()``
locationManager.delegate = self
if (CLLocationManager.locationServicesEnabled())
{
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.allowsBackgroundLocationUpdates = true
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
// Do any additional setup after loading the view, typically from a nib.
}
}
extension ViewController : CLLocationManagerDelegate
{
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus)
{
if status == .authorizedAlways
{
if(CLLocationManager .locationServicesEnabled())
{
locationManager.startUpdatingLocation()
mapViewTest.isMyLocationEnabled = true
mapViewTest.settings.myLocationButton = true
}
}
}
func locationManager(manager: CLLocationManager, didUpdateToLocation newLocation: CLLocation, fromLocation oldLocation: CLLocation)
{
mapViewTest.camera = GMSCameraPosition(target: (newLocation.coordinate), zoom: 15, bearing: 0, viewingAngle: 0)
currentLocation = newLocation
currentLatitude = newLocation.coordinate.latitude
currentLongitude = newLocation.coordinate.longitude
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError)
{
print("Errors: " + error.localizedDescription)
}
}
From your code you are working with Swift 3, and in Swift 3 CLLocationManagerDelegate method's signature is changed like this.
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
}
//func locationManager(_ manager: CLLocationManager, didUpdateTo newLocation: CLLocation,
from oldLocation: CLLocation) is deprecated with below one
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
}
Check Apple Documentation on CLLocationManagerDelegate for more details.
After checking your code i found some changes you needs to do as follow,
note : I have only added the code having issue here that of location manager
import UIKit
import CoreLocation
class ViewController: UIViewController {
let locationManager = CLLocationManager()
var currentLocation :CLLocation = CLLocation(latitude: 0.0, longitude: 0.0)
var currentLatitude : Double = 0.0
var currentLongitude : Double = 0.0
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager.delegate = self
if (CLLocationManager.locationServicesEnabled())
{
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.allowsBackgroundLocationUpdates = true
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension ViewController : CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
}
func locationManager(_ manager: CLLocationManager, didFinishDeferredUpdatesWithError error: Error?) {
print("Errors: " + (error?.localizedDescription)!)
}
}
Also add below lines in .plist file if not added,
<key>NSLocationWhenInUseUsageDescription</key>
<string>$(PRODUCT_NAME) location use</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>$(PRODUCT_NAME) always uses location </string>
Add these two properties in your info.plist
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
you need to put the mapview delegate to self.
try this:
override func viewDidLoad() {
super.viewDidLoad()
// User Location Settings
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
// Google Maps Delegate
mapView.delegate = self
}
// View will appear
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
// Google maps settings
mapView.isMyLocationEnabled = true
mapView.settings.myLocationButton = true
// Get location if autorized
if (CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedWhenInUse) {
let (latitude, longitude) = self.getLocation()
mapView.camera = GMSCameraPosition.camera(
withLatitude: latitude,
longitude: longitude,
zoom: 14)
}
}
//Get the user location
func getLocation() -> (latitude: CLLocationDegrees, longitude: CLLocationDegrees) {
let latitude = (locationManager.location?.coordinate.latitude)!
let longitude = (locationManager.location?.coordinate.longitude)!
return (latitude, longitude)
}

locationManager:didUpdateLocations never called

I have this code in my ViewController:
#IBAction func testButton(sender: UIButton) {
let locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
print("\(CLLocationManager.locationServicesEnabled())")
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
print("Started updating location")
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation: CLLocation = locations[0]
let long = userLocation.coordinate.longitude
let lat = userLocation.coordinate.latitude
print("\(long), \(lat)")
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("Location update failed: \(error)")
}
NSLocationWhenInUseUsageDescription in my plist. It should just work according to all information I could find, but it just outputs
true
Started updating location
Is edit 2 of this question true? If so, what would be the best way to move this out of the viewController?
Before startUpdatingLocation(), have to ask for permission using requestWhenInUseAuthorization() first.
So your codes in ViewController will be similar like the following or you can download a sample project here.
class ViewController: UIViewController, CLLocationManagerDelegate {
let locationManager: CLLocationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.testButton()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func testButton() {
if CLLocationManager.authorizationStatus() != .AuthorizedWhenInUse {
self.locationManager.requestWhenInUseAuthorization()
return
}
self.locationManager.startUpdatingLocation()
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation: CLLocation = locations[0]
let long = userLocation.coordinate.longitude
let lat = userLocation.coordinate.latitude
print("\(long), \(lat)")
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("Location update failed: \(error)")
}
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .AuthorizedWhenInUse {
self.testButton()
}
}
}

Swift Not Reaching LocationManager Function

I am trying to get my location in order to check how far I am from a certain longitude and latitude.
For some reason the program never reaches the LocationManager Function where I want to grab my coordinates.
I have set up the correct properties in info.plist and the app does ask for permission.
I added a function to check for errors and got:
didFailWithError Error Domain=kCLErrorDomain Code=0 "(null)"
import UIKit
import CoreLocation
import MapKit
class ViewController: UIViewController, CLLocationManagerDelegate {
var locationManager:CLLocationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
print("location on")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("REACHED FUNCTION")
}
}
If you are using iOS 8.0 and later you need to ask for permission before starting to update location. You can use following code for that
if #available(iOS 8.0, *) {
locationManager.requestWhenInUseAuthorization()
}
Above code will go in viewDidLoad. And implement following delegate method
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
switch status {
case .AuthorizedWhenInUse:
locationManager.startUpdatingLocation()
break
case .AuthorizedAlways:
locationManager.startUpdatingLocation()
break
default:
break
}
}

How to get location from GPS when offline in Swift?

I want to make app can get location (latitude & longitude) with no internet, and someone tell me use CCLocationManager, here.
And I testing with my code:
var locationManager:CLLocationManager!
#IBOutlet weak var locationTextField: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
let authstate = CLLocationManager.authorizationStatus()
if(authstate == CLAuthorizationStatus.NotDetermined){
print("Not Authorised")
locationManager.requestWhenInUseAuthorization()
}
print("first")
locationTextField.text = "11"
// 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("success \(locations.count)")
let location:CLLocation = locations[locations.count - 1] as CLLocation
print("aa:\(location.coordinate.latitude) \(location.coordinate.longitude)aa")
locationTextField.text = location.description
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("Couldn't get your location with \(error.description)")
}
But it just work with internet and when I turn off wifi, my app log: Couldn't get your location with Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)"
Maybe I'm wrong somewhere, any helps, thanks.

CLLocation Manager in Swift to get Location of User

I am trying to convert an old app in ObjC to Swift as a practice exercise and have ran in to some issues. The way I had it in the old app, it was establishing the CLLocation Manager and then I would use:
manager = [[CLLocationManager alloc]init];
manager.delegate = self;
manager.desiredAccuracy = kCLLocationAccuracyBest;
[manager startUpdatingLocation]
which would call automatically:
-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
}
and from there I could extract all the information I needed. But in swift, there is no autocompletion of this method and I cannot figure out how to reproduce it. The documentation says that
startUpdatingLocation()
will still be called by the delegate, but it isn't happening.
This is what I have so far:
import UIKit
import corelocation
class ViewController: UIViewController,CLLocationManagerDelegate{
#IBOutlet var gpsResult : UILabel
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[]) {
println("locations = \(locations)")
gpsResult.text = "success"
}
}
Any help or pointers on where to look would be appreciated. Thanks.
EDIT: Updated from Suggestions, but still not working
EDIT2: Seems to be some bug not allowing the method to work properly in the ViewController
You are missing two things. First, you have to ask for permission using requestAlwaysAuthorization or requestWhenInUseAuthorization(). So your viewDidLoad() should be like this:
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
Second, edit your Info.plist as indicated here.
First add this two line in plist file
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
Then this is class working complete implement this
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)")
}
}
}
I'm not sure why, but it seems like startUpdatingLocation isn't presenting the user prompt on the iOS 7 simulator, but when I enabled it manually it worked as expected if I used the newer form of the delegate method:
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)")
}
The format you're using has been deprecated since iOS 5 or 6, so apparently it's not supported at all by the swift bridging layers.
had the same issue. didUpdateLocations - was not working. Run your app. Go to the Settings page -> Privacy -> Location and turn off Location Services. didFailWithError will catch the error about absent Location Services. Then turn it on. Since that moment didUpdateLocations will catch locations.
Here is my very simple code that works:
first add Core Location framework in General/Linked Frameworks and Libraries
then add following into Info.plist:
<key>NSLocationWhenInUseUsageDescription</key>
<string>blablabla</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>blablabla</string>
this is my ViewController.swift file:
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)")
}
}
For 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)")
}
}
I hope there are two ways.
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()
}
Implementing 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
}
Checking CLLocationDelegate Authorization:
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
}
}
Note: changeStatusToOn or changeStatusToOff is a UILabel Extenion method which makes the Label text On/Off with Green/Red Colors.
don't forget to add
NSLocationWhenInUseUsageDescription or
NSLocationAlwaysUsageDescription
in your configuration file (target/Info/custom iOS target properties
Add bellow 2 property in info.plist
NSLocationWhenInUseUsageDescription : Location information is used for fraud prevention
Privacy - Location Usage Description : Location information is used for fraud prevention
If you want to get the user location updated by default, without clicking 'Simulate location' everytime, go to
YourProject-->Build Phases-->Link Binary with libraries-->Add corelocation.framework
The location gets updated automatically/by default when you run the app in the simulator. Tested and works in Swift 2 !
This will ask for permission and track if given permission else quit with an alert. Stops tracking on back button press.
