title: Google Maps SDK for iOS keeps increasing usage of memory
body: <p>I've built a simple application that shows markers on map ,and I load its x,y from JSON file from a server the markers are click-able so once you on any marker it takes you to another <code>UIViewController</code> (Let's name it <code>BViewController</code>). I've monitored the Memory Usage so each time I go back from <code>BViewController</code> to <code>MapViewController</code> (Which is the map inside) it's just double the usage of memory I tried to set it to <code>nill</code> or Remove it from <code>superView</code> , but nothing changed </p>
  
  <p>My Project use <strong>ARC</strong>.</p>
  
  <p>So please any idea how to reduce this usage.
  <br/>Thanks in advance </p>
