title: Set the zoom for MKMapCamera and MKUserTrackingMode to be equal in a view controller
body: <p>I'm using both <code>MKUserTrackingMode</code> and <code>MKMapCamera</code> in the same ViewController to be able to track the user when they're navigating and to rotate the camera accordingly as the user travels along their route. <code>MKUserTrackingMode</code> zooms into a certain level, about 4,700 meters above the current location (using the iPhone 6 simulator) and <code>MKMapCamera</code> makes you specificy the eyeAltitude. Is there a way to make the <code>MKMapCamera</code> zoom level equal to the <code>MKUserTrackingMode</code> so that it doesn't first zoom to satisfy the <code>MKMapCamera</code> parameter then readjust to accompany the <code>MKUserTrackingMode</code> function?</p>
  
  <p><code>MKMapCamera</code> is in <code>convenience init</code> and <code>MKUserTrackingMode</code> is in <code>viewDidAppear</code></p>
