title: Black Translucent Navigation Bar + MKMapView -> Setting map center is not visually correct
body: <p>I have a Map View in a Navigation Controller under translucent black navigation, status and search and toolbars.</p>
  
  <p>The actual height of the map includes the area below these bars.</p>
  
  <p>The <strong>+</strong> left accessory button makes the map center on the Pin.</p>

  <p>The left image is before the map is centered to the pin's coordinates. </p>
  
  <p>The right one is when the map in centered to the pin's coordinates.</p>
  
  <p>The problem is that the center should be the center of the visible map area and not the whole map area. (which causes the pin to not appear in the center of the map.</p>
  
  <p>Is there some offset or boundary setting I can do so the Map View will center correctly? </p>
