didUpdateLocations not being called

Question

I have my object set as the locationManager's delegate, and the didChangeAuthorizationStatus method is called, which does this:

func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    if status == CLAuthorizationStatus.AuthorizedWhenInUse {
        self.locationManager.startUpdatingLocation()
    }
}

I also have this method, which never gets called following this:

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    if locations.count == 0 {
        return
    }

    //Do stuff
}

Any thoughts as to why this might not be being called? I suppose the object being deallocated is an option, but then it'd also be deallocated by the time it hit the authorizationStatus method.

Answer 1

This is way late for an answer, but I stumbled across this when I was having the same issue (didChangeAuthorizationStatus was being called but not didUpdateLocations). Well of course it's something not code related, but rather I was testing in the simulator which did not have a location set. Thus the location was never found, resulting in didUpdateLocations never being called.

To fix this... in the simulator go to Debug -> Location-> <choose location>.

EDIT It should also be noted that locationManager:didFailWithError: will run if the location is not set in the simulator, as you'd expect.

It's working in iOS 10 and iOS 11 as well,

Create property of CLLocationManager using strong and add CLLocationManagerDelegate

@property (strong, nonatomic) CLLocationManager *locationManager;

Add below properties into your info.plist file

Privacy - Location When In Use Usage Description
Privacy - Location Always Usage Description
Privacy - Location Usage Description

Add below method in to your .m file

-(void)getCurrentLocation
{
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate=self;
    self.locationManager.desiredAccuracy=kCLLocationAccuracyBest;
    self.locationManager.distanceFilter=kCLDistanceFilterNone;
    [self.locationManager requestWhenInUseAuthorization];
    [self.locationManager startMonitoringSignificantLocationChanges];
    [self.locationManager startUpdatingLocation];
}

and just call [self getCurrentLocation] method.

Here is a snippet from my app:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    ...
    locationManager.delegate = self
    locationManager.activityType = CLActivityType.Fitness
    locationManager.distanceFilter = 10   // 10m
    locationManager.requestAlwaysAuthorization()

    // get current location
    if CLLocationManager.authorizationStatus() == CLAuthorizationStatus.Authorized {
        locationManager.startUpdatingLocation()
    }
}

func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    if status == .Authorized {
        locationManager.startUpdatingLocation()
    }
}

You have to put the NSLocationAlwaysUsageDescription key in your Info.plist and set the value to the authorization question. This is a requirement as of iOS 8.
