title: Is there any library to implement twitter web view login dialog in iOS
body: <p>i have an app that want to share to twitter</p>
  
  <p>when user click the share button and he has a token the app will process in the background and tweet using predefined message (user cannot change the message)</p>
  
  <p>but if he/she doesn't have the token then the app will show popup login webview dialog 
  to the user with our app name like in the picture.</p>
  
  <p>After he/she successfully login dismiss login dialog and the app will repeat step 1 (tweet in background)</p>
