didUpdateToLocation not called when application is in background
<p>I am currently writing an app that will get location in both foreground and background. </p>

<p>My app work correctly when in foreground, however, no didUpdateToLocation callback is received when it is in background. Please help.</p>

<p>Below is the code I used to init. the location manager.</p>

<pre><code>locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
</code></pre>
