title: Facebook publish message to wall with dialog box
body: <p>I'm using the new SDK FACEBOOK API connect for my iphone application.
  With this code my string is direct publish to wall without any dialog box. </p>
  
  <pre><code> NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                 @"test message",  @"message",
                                 nil]; 
   [facebook requestWithGraphPath:@"/me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];
  </code></pre>
  
  <p>I would like to post a simple string in the wall of user logged with open dialog box, is this possible?</p>
