Google Maps SDK for iOS crash after publishing to App Store

I have Goole Map (v1.5) integrated in my iOS App and it works fine when I test it on a real device (iPad 4 iOS 6.1) in Debug mode.

I published my App and when users open the map the application crashes.

I cannot figure where the problem is and why does it crash.

Edit:

ELocation.m loadView :

- (void)loadView {

    _locationManager = [[CLLocationManager alloc] init];

    _locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    _locationManager.delegate = self;

    [_locationManager startUpdatingLocation];

    _destLocation = nil;

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:_locationManager.location.coordinate.latitude longitude:_locationManager.location.coordinate.longitude zoom:12]; //**line 45**

    mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];

    mapView.settings.zoomGestures = YES;

    mapView.settings.myLocationButton = YES;

    mapView.myLocationEnabled = YES;

    mapView.delegate = self;

    self.view = mapView;

}

When you call [_locationManager startUpdatingLocation] then you will receive a callback via locationManager:didUpdateLocations: when a location is available, asynchronously at some later point. Until then _locationManager.location may be nil - although it might not be if your app has previously cached a location.

This might be the cause of your crash for users who've not run the app before, as on line 45 you're assuming you have a valid location to create the camera position at. Although I'm not sure, since calling .coordinate.latitude on nil should just return 0 instead of crashing.

It may be that your users are being prompted for access to their location, and that attempting to access the location before they've answered yes is what is causing the crash. To reproduce that on your own device you'll need to reset your location & privacy settings. Do this via Settings -> General -> Reset -> Reset Location & Privacy. Unfortunately this resets it for all of your apps and for all of your privacy options (ie location, photos, contacts, etc). Even if you delete and then reinstall your app, iOS will remember that you've previously answered yes. An easier way might be to try temporarily changing your bundle ID, but then you'll also need to get a new Google maps key.
