title: How does the uiwebview gets access token to like the facebookpage (through iFrame)?
body: <p>In my project user get logged-in through Facebook native app(FBConnect) and i kept the user's access token. In my app i have a like button which display the iframe of a facebookpage like button and now when user press the page like button the facebook ask the user to sign in again.
  Although the user is currently logged-in and the token is validand i am passing the access token in the iframe 
  Here is the code which i am using for creating iframe.</p>
  
  <pre><code>NSString *str=[NSString stringWithFormat:@"&lt;iframe src=\"https://www.facebook.com/plugins/likebox.php?id=XXXXXXXXXXXXXXX&amp;access_token=%@&amp;amp;width=292&amp;amp;connections=0&amp;amp;stream=false&amp;amp;header=false&amp;amp;height=62\" scrolling=\"no\" frameborder=\"0\" style=\"border:none; overflow:hidden; width:282px; height:62px;\" allowTransparency=\"true\"&gt;&lt;/iframe&gt;",accesstoken];
  NSString *likeButtonHtml = [NSString stringWithFormat:@"&lt;HTML&gt;&lt;BODY&gt;%@&lt;/BODY&gt;&lt;/HTML&gt;", str];
    [webview loadHTMLString:likeButtonHtml baseURL:[NSURL URLWithString:@""]];
  </code></pre>
  
  <p>Please tell me how will i avoid this second login for like a page on iframe</p>
