didUpdateLocations not called

I'm trying to get my current location, but the break point in didUpdateLocations is never being called.

LocationManager:

locationManager = [[CLLocationManager alloc] init];
[locationManager setDelegate:self];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[locationManager setDesiredAccuracy:kCLDistanceFilterNone];
[locationManager startUpdatingLocation];

Delegate method:

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations;

I confirmed that location services and enabled and authorized.

Why is the locationManager delegate method not being called like it should?

Furthermore in iOS8 you must have two extra things:

  • Add a key to your Info.plist and request authorization from the location manager asking it to start.

    • NSLocationWhenInUseUsageDescription

    • NSLocationAlwaysUsageDescription

  • You need to request authorization for the corresponding location method.

    • [self.locationManager requestWhenInUseAuthorization]

    • [self.locationManager requestAlwaysAuthorization]

Code example:

self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
// Check for iOS 8. Without this guard the code will crash with "unknown selector" on iOS 7.
if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
    [self.locationManager requestWhenInUseAuthorization];
}
[self.locationManager startUpdatingLocation];
