I am facing a strange problem. I am using - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations to get device location. It is working fine on simulator (iOS 6 and iOS 7) and iPhone 4S running iOS 6.1.3. It is also working fine when I connect iPhone 4 running iOS 7 to system and install the app but as soon as I unplug the device and re-run the app, this method doesn't get called and I don't get the location. How can I overcome this issue?

How did you setup you location Manager?

Do you have in your interface: 

@interface ViewController : UIViewController <CLLocationManagerDelegate> {
    @property (strong, nonatomic) CLLocationManager *locationManager;
}

Then in implementation in viewDidLoad:

// setup location manager
    if ([CLLocationManager locationServicesEnabled]) {
        _locationManager = [[CLLocationManager alloc] init];

        _locationManager.desiredAccuracy = kCLLocationAccuracyBest;
        _locationManager.delegate = self;

        [_locationManager startUpdatingLocation];
    }

And you need to implement the delegate:

locationManager:didUpdateLocations:

Be careful: In IOS 7 

locationManager:didUpdateToLocation:fromLocation

is deprecated. Apple link to CLLocationManagerDelegate

  • `headingAvailable` is deprecated since `iOS 4` and I'm using `locationManager:didUpdateLocations:` – Ankur Arya Dec 17 '13 at 10:12
  • a..sorry. headingAvailable doesn't fit in (copy paste mistake). But anyways. headingAvailable property was deprecated. This is a call to recommended +(BOOL)headingAvailable (i changed it to locationServicesEnabled). Interesting that it does't work. Have you tried changing to _locationbManager.distanceFilter = kCLDistanceFilterNone; ? That should notify delegate of all movements. – y0gie007 Dec 17 '13 at 10:42
  • I've exactly the same code as yours apart from the `if` condition. – Ankur Arya Dec 17 '13 at 11:29
  • I've created a simple project and it works for me (iPhone 5, iOS 7.0.4) as well on the simulators: git@github.com:rendulic/CLLocationTest.git – y0gie007 Dec 19 '13 at 10:29
  • Thanks for your time, your code is working fine and the strange thing is that my code is also working today, tho I didn't change anything whatsoever – Ankur Arya Dec 19 '13 at 10:46
  • No problem. I've noticed some problems in simulators when geo location is in question. Not yet on a device. Anyhow. Its working :) – y0gie007 Dec 19 '13 at 11:10
  • I'm marking your answer as correct until someone comes up with more precise answer to this problem. – Ankur Arya Dec 19 '13 at 11:29
