title: iOS facebook login ask for permission every time
body: <p>I'm using FBLoginView in my iOS app. I do everything like in <a href="https://developers.facebook.com/docs/ios/login-tutorial" rel="nofollow">this</a> tutorial. Everything works great except one thing. When I logout and then login again via facebook it opens view with ask for grant permission to app with information I grant permission already. How can I skip this view after grant permission first time? </p>
