title: iOS Force GCM to refresh registration token
body: <p>I use <strong>GCM</strong> in my Swift app and would like to ask GCM a new registration token.</p>
  
  <p>I know that it's done automatically by GCM and I handle it in <strong>onTokenRefresh</strong>, but I want to know if it's possible to <strong>request GCM to refresh the token manually</strong> (to have a different one).</p>
  
  <p>I tried to unregister for remote notification and register back to run the process (<strong>tokenWithAuthorizedEntity</strong> etc ...) but the registration token sent is the same. </p>
  
  <p>any solution to do this ?</p>
