title: iOS Facebook SDK SSO Safari log out
body: <p>I use the latest <code>Facebook</code> SDK in my <code>iOS</code> app. </p>
  
  <p>It uses single sign on, so even after calling <code>Facebook</code> logout method, when user log in again, dialog window saying he is already logged in fine. </p>
  
  <p>In other <code>iOS</code> applications there is a logout button on Safari web view, so user can simply log out from app.</p>
  
  <p>My question is how I can implement such <code>webView</code> in my application?</p>
  
  <p>I know that I can use <code>FBDialog</code> instead of Safari window to control logout process but I need to have possibility to logout exactly from Safari web view. May be the window with logout button is accessible only in the old versions of SDK?</p>
