title: ios 7 MKMapView draggable annotation change it's position when map is scrolled
body: <p>I am updating my app (MyWorld) to iOS 7. 
  One of the features of the app is that you can drag pin on the map view.
  It seems to be broken in iOS7.</p>
  
  <p>Steps to recreate the problem:</p>
  
  <ul>
  <li><strong>Adding Annotation to the map:</strong> - works fine</li>
  <li><strong>Moving Annotation (Dragging)</strong> works fine</li>
  <li><strong>Scrolling the map: Problem</strong></li>
  </ul>
  
  <p>Whenever I scroll the map view annotation is moved with the map. It seems like it's not attached to the right view or layer?? If the pin is not dragged map view seems to work fine and annotation stays in defined position.
  I wonder if this is a mistake on my side or a known issue?</p>
  
  <p>I created a dummy MapViewTest project that ilusstrates the problem on github: <a href="https://github.com/DJMobileInc/MapViewTest" rel="noreferrer">https://github.com/DJMobileInc/MapViewTest</a></p>
