title: MKMapView Not Calling regionDidChangeAnimated on Pan
body: <p>I have an app with a MKMapView and code that is called each time the map changes locations (in regionDidChangeAnimated). When the app initially loads, regionDidChangeAnimated is called on pans (swipes), pinches, taps and buttons that explicitly update the map coordinates. After loading other views and coming back to the map the regionDidChangeAnimated is only called for taps and the buttons that explicitly update the map. Panning the map and pinches no longer call regionDidChangeAnimated. </p>
  
  <p>I have looked at this <a href="https://stackoverflow.com/questions/4118596/mkmapview-regiondidchangeanimated-not-always-called">stackoverflow post</a> which did not solve this issue. The forum posts on <a href="https://devforums.apple.com/message/525411" rel="nofollow noreferrer">devforums</a> and <a href="http://www.iphonedevsdk.com/forum/iphone-sdk-development/79199-regiondidchangeanimated-not-always-firing.html" rel="nofollow noreferrer">iphonedevsdk</a> also did not work. Does anyone know what causes this issue? I am not adding any subviews to MKMapView.</p>
