title: Tracking mode with MapKit
body: <p>I have a question about UserLocation e MapKit.</p>
  
  <p>I would to follow the user location on the map (automatically moves the map if user location changes) If the user tap (or pan or pinch) the map I would to disable the 'follow mode' (like Apple map app)..</p>
  
  <p>I tried this method:</p>
  
  <pre><code>[_mapView setUserTrackingMode:MKUserTrackingModeFollowWithHeading animated:YES];
  </code></pre>
  
  <p>This work well but I have some questions about it:</p>
  
  <ul>
  <li><p>Is possible to set a particular zoom level during the 'follow mode'?  </p></li>
  <li><p>I noticed that if they are in 'follow mode' and I make a pinch the map, the 'follow mode' mode is not interrupted. If I still pinch the map (or pan) 'follow mode' is interrupted. I do not understand when you really stop this mode..</p></li>
  </ul>
