title: When does didUpdateLocation get called?
body: <p>Let's say you want to focus your MapView on the current location, then you write some code in <code>didUpdateLocation</code> which processes the current location coordinates.</p>
  <p>But if you don't call  <code>requestLocation</code> or <code>startUpdatingLocaion</code> on your <code>CLLocationManager</code> object, the method never gets called. Is that correct?</p>
  <p>But wether you call <code>requestLocation</code> or <code>startUpdatingLocation</code> if you look on your <code>MapView</code> the blue dot which shows your location moves (e.g. you simulate movement) but didUpdateLocation won't get called automatically.</p>
  <p>I am trying to understand why they made a delegate method when you kind of have to call it yourself.</p>
