Location services permission alert disappears - ios

I am asking for requestWhenInUseAuthorization from CLLocationManager and the user prompt displays but then quickly disappears.
According to other posts on SO it says that you have to declare your CLLocationManager var at the class level to fix this.
Problem is that I am already doing this and this still happens.
Any help would be appreciated.
class myLocation: CLLocationManagerDelegate {
var locationManager:CLLocationManager?
// Have also tried it as: let locationManager = CLLocationManager()
func start() {
if CLLocationManager.locationServicesEnabled() {
self.locationManager = CLLocationManager()
guard let manager = self.locationManager else {
print("Error creating Location Manager")
return
}
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
manager.requestWhenInUseAuthorization()
}
else {
print("Location Services Disabled")
}
}
//Delegate Methods
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
switch status {
case .authorizedAlways, .authorizedWhenInUse:
manager.startUpdatingLocation()
default:
manager.requestWhenInUseAuthorization()
}
}
...
}

The key to fixing this was that the var I instantiated this class too was a local var. I moved that to a class var and it no longer disappears.
So for example:
class ViewController: UIViewController {
let location = myLocation.init()
override func viewDidLoad() {
super.viewDidLoad()
location.start()
}
}

swift user location - update if move

So I have been able to get the users location via the following code.
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status != .authorizedWhenInUse {return}
print("test LOCATION BELOW")
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
let locValue: CLLocationCoordinate2D = manager.location!.coordinate
print("UUID: \(String(describing: uuid)) locations = \(locValue.latitude) \(locValue.longitude)")
}
However I want to watch the users location and if they move update their location.
I am wondering how do I get this code to keep checking for the users location?
My
override func viewDidLoad(){
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.requestAlwaysAuthorization()}
I get it popping up the request and I approve it but it does not run the code
Here is how you can get the location data. The code is similar to yours but with a bit of change and additions.
First check if you already have user's permission to get their location data.
func isLocationServicesEnabled() -> Bool {
if CLLocationManager.locationServicesEnabled() {
switch(CLLocationManager.authorizationStatus()) {
case .notDetermined, .restricted, .denied:
return false
case .authorizedAlways, .authorizedWhenInUse:
return true
#unknown default:
return false
}
}
return false
}
If this method returns false you can ask for authorization.
// Initialize manager in your viewDidLoad
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
locationManager.delegate = self
// Do other stuff
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
// Check for auth
if isLocationServicesEnabled() {
locationManager.startUpdatingLocation()
} else {
locationManager.requestWhenInUseAuthorization()
}
// Do other stuff
}
Finally in your CLLocationManagerDelegate implementation get the coordinates.
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let location = locations.last?.coordinate else { return }
// Use location.latitude and location.longitude here
// If you don't want to receive any more location data then call
locationManager.stopUpdatingLocation()
}
First, you have to check that you have user's permission to get their location data
func checkLocationServicesAuthorization() -> Bool {
if CLLocationManager.locationServicesEnabled() {
switch CLLocationManager.authorizationStatus() {
case .notDetermined:
return false
case .restricted, .denied:
//code for open settings screen in user’s phone
return false
case .authorizedWhenInUse, .authorizedAlways:
return true
default:
return false
}
} else {
//code for open settings screen in user’s phone
}
return false
}
And
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
locationManager.delegate = self
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
if checkLocationServicesAuthorization() {
locationManager.startUpdatingLocation()
} else {
locationManager.requestWhenInUseAuthorization()
}
}
You can use delegate method didUpdateLocations of CLLocationManagerDelegate and don't forgot to connect delegate yourLocationManager.delegate = self
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation:CLLocation = locations[0] as CLLocation
// Call stopUpdatingLocation() to stop listening for location updates, other wise this function will be called every time when user location changes.
// yourLocationManager.stopUpdatingLocation()
guard let locValue: CLLocationCoordinate2D = manager.location?.coordinate else { return }
let latitude = String.init(userLocation.coordinate.latitude)
let longitude = String.init(userLocation.coordinate.longitude)
print("\(latitude), \(longitude)")
}

Location manager didUpdateLocations not being called

For some reason didUpdateLocations is not being called, even when I set the delegate to the view controller. In info.plist I set the key Privacy - Location When In Use Usage Description to a description. So I'm not sure what I could be doing wrong?
import MapKit
import CoreLocation
class OptionsViewController: UIViewController, UITableViewDelegate, CLLocationManagerDelegate {
override func viewDidLoad() {
//Ask user for location
locationManager = CLLocationManager()
locationManager.requestWhenInUseAuthorization()
//Use users current location if no starting point set
if CLLocationManager.locationServicesEnabled() {
let locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
}
}
override func viewDidAppear(_ animated: Bool) {
locationManager = CLLocationManager()
locationManager.requestWhenInUseAuthorization()
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error){
locationManager.stopUpdatingLocation()
print(error)
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("Did update location called?")
let locValue:CLLocationCoordinate2D = manager.location!.coordinate
print("locations = \(locValue.latitude) \(locValue.longitude)")
}
}
Problem is here:
override func viewDidAppear(_ animated: Bool) {
locationManager = CLLocationManager()
locationManager.requestWhenInUseAuthorization()
}
This method will be called after viewDidLoad, but you new created a locationManager later in viewDidAppear and not pointed its delegate to self. That's why the delegate(self)'s methods is not be called.
The improved but not the best way is:
class OptionsViewController: UIViewController, UITableViewDelegate, CLLocationManagerDelegate {
let locationManager = CLLocationManager()
override func viewDidLoad() {
//Ask user for location
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
//Use users current location if no starting point set
if CLLocationManager.locationServicesEnabled() {
if CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedWhenInUse
|| CLLocationManager.authorizationStatus() == CLAuthorizationStatus.authorizedAlways {
locationManager.startUpdatingLocation()
}
else{
locationManager.requestWhenInUseAuthorization()
}
}
else{
//Alert user to open location service, bra bra bra here...
}
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
//... nothing need to do for location here
}
public func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status == CLAuthorizationStatus.authorizedWhenInUse
|| status == CLAuthorizationStatus.authorizedAlways {
locationManager.startUpdatingLocation()
}
else{
//other procedures when location service is not permitted.
}
}
//......
}

iOS swift Location Manager not getting updated properly

I am using CLLocationManager for getting user location. I need to update user location when they move. I am using this code :
import UIKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
private var locationManager = CLLocationManager()
lazy var locations = [CLLocation]()
var op:String = ""
#IBOutlet weak var resultTxt: UITextView!
#IBAction func Start(sender: AnyObject) {
startLocationManager()
showResult()
}
override func viewDidLoad() {
super.viewDidLoad()
}
func startLocationManager(){
locationManager.delegate = self
locationManager.allowsBackgroundLocationUpdates = true
locationManager.distanceFilter = kCLDistanceFilterNone
locationManager.pausesLocationUpdatesAutomatically = false
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
func startLocationTracking() {
NSLog("startLocationTracking")
if CLLocationManager.locationServicesEnabled() {
switch(CLLocationManager.authorizationStatus()) {
case .NotDetermined, .Restricted, .Denied:
print("No access")
self.startLocationManager()
case .AuthorizedAlways, .AuthorizedWhenInUse:
NSLog("authorizationStatus authorized")
}
} else {
print("Location services are not enabled")
self.startLocationManager()
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
for location in locations {
let howRecent = location.timestamp.timeIntervalSinceNow
if abs(howRecent) < 10 && location.horizontalAccuracy < 20 {
//update distance
self.locations.append(location)
showResult()
}
}
}
func showResult(){
let currentDate = NSDate()
let res:String = "Result LAT : \(self.locations.last?.coordinate.latitude) AND LNG : \(self.locations.last?.coordinate.longitude) Time : \(currentDate.toShortTimeString()) \n "
op += res
self.resultTxt.text = op
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
And I have already added NSLocationAlwaysUsageDescription and NSLocationWhenInUseUsageDescription in .plist.
This code works fine for the first time. But when the user moves "didUpdateLocations" is not getting fired.
Can any one please help me, what I am doing wrong?
Try to add these lines, to be able to monitoring significant location changes when user moves:
locationManager.startMonitoringSignificantLocationChanges()
locationManager.distanceFilter = 300 //value is up to you

Issues getting device/user location with iOS App, Swift

Setup:
Xcode 7.3 (7D175)
Swift 2
Device is an iPad with iOS 9.3.1
I have a Swift class called LocationUtility, I am using it like so in a ViewController:
let locationUtil = LocationUtility()
locationUtil.initLocationManager()
The initLocationManager() function sets the CLLocationManager.delegate to my LocationUtility class:
func initLocationManager() {
seenError = false
locationFixAchieved = false
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
if CLLocationManager.locationServicesEnabled() {
locationManager.startUpdatingLocation()
}
}
The following delegate func is never being called:
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
I have NSLocationAlwaysUsageDescription string set in my Info.plist
On my iPad, Privacy -> Location Services is Enabled.
My LocationUtility class is something a put together with, mostly code from other stackoverflow questions and answers about location functionality in Swift and iOS 8 and beyond. From my perspective I have all the right settings in my APP and on my device to be receiving location information.
Here is my complete LocationUtility class source code:
import UIKit
import Foundation
import CoreLocation
class LocationUtility: UIViewController, CLLocationManagerDelegate {
var locationStatus : NSString = "Not Started"
var locationManager: CLLocationManager!
var seenError : Bool = false
var locationFixAchieved : Bool = false
var currentLocation:CLLocation? = nil
func initLocationManager() {
seenError = false
locationFixAchieved = false
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
if CLLocationManager.locationServicesEnabled() {
//locationManager.delegate = self
//locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.startUpdatingLocation()
}
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("LocationUtility -> didFailWithError()")
locationManager.stopUpdatingLocation()
if (seenError == false) {
seenError = true
print(error)
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("LocationUtility -> didUpdateLocations()")
if (locationFixAchieved == false) {
locationFixAchieved = true
//var locationArray = locations as NSArray
currentLocation = locations.last! as CLLocation
let coord = currentLocation!.coordinate
print("user current location")
print(coord.latitude)
print(coord.longitude)
}
}
// authorization status
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
print("LocationUtility -> didChangeAuthorizationStatus()!")
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
}
if (shouldIAllow == true) {
NSLog("Location to Allowed")
// Start location services
locationManager.startUpdatingLocation()
} else {
NSLog("Denied access: \(locationStatus)")
}
}
}
The symptoms you describe strongly suggest that your LocationUtility instance is getting deallocated, which deallocates the CLLocationManager and stops the entire process. It's not clear where you're instantiating LocationUtility but you need to make sure it's some place where the instance will remain "live" in memory while CLLocationManager does its things. If the view controller is deallocated, for example, then its instance vars will be deallocated, which looks like it probably includes your location manager.
Your question initially asked if the location manager had to be in the app delegate. It doesn't, of course, but it does have to be someplace that can prevent it from being deallocated while location updates are in progress.
If you're unsure when the LocationManager is getting deallocated, try implementing deinit on it and setting a breakpoint on that method.

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.
