title: Does FacebookSDK always show LaunchScreen after Share or Login and before get back to the current screen?
body: <p>I am developing an app with <code>Facebook</code> share and login. When I do Login or I share something in <code>Facebook</code>, the <code>LaunchScreen</code> of my app is displayed before show the current <code>view</code>. It is just a second, but I would like to know if there is any way to avoid that step.</p>
  
  <p>Thank you. </p>
