title: Stop iOS 7 MKMapView from leaking memory
body: <p>I've noticed that my app leaks memory, but if I take the <code>MKMapView</code> out the memory problem goes away. </p>
  
  <p>To test the theory, I made a dead simple project that has a view that pushes a view with a <code>MKMapView</code> in it and pops and pushes. Nothing more. No code in the view controllers, everthing done via storyboard.</p>
  
  <p>If I go back and forth to the map view, it starts about 3MB after doing pushing and popping the view with the map in it this about 15 times the memory is around 230MB.</p>
  
  <p>Anyone else seen this?   Seems like a pretty big bug. Is there a different way to use <code>MKMapView</code> that will prevent it from leaking so much?</p>
