title: How to stop updating location once I get current location?
body: <p>I'm using Parse and with geoPointForCurrentLocationInBackground I can stop updating once a location is received without having to manually stop it.</p>
  
  <p>How do I stop updating location immediately right after I receive location using CLLocationManager?</p>
  
  <p><strong>Edit</strong></p>
  
  <p>I know [self.locationManager stopUpdatingLocation]; stops it.
  What I'm really asking is, how do I know I've received location for the first time then stop it immediately? </p>
