  <p>I have successfully completed login  process but the problem is Login button becomes Logout button after successful authentication. But I want to implement Logout button in a separate view(<code>CustomViewController</code>).</p>
  
  <p>The main thing is after successful login authentication user has to be redirected to separate viewController where I need to place logout button through that user can be logged out.But in this tutorial Login and logout implemented in the same view for same button. suggest me if you know any sample code or link like this.</p>
