body: <p>I have been searching stackoverflow and the internet and did no find a working solution for my intention.</p>
  
  <p>I want to call a method with a string as parameter which is then posted to the facebook wall without showing a dialog. Of course only when a valid session is available.</p>
  
  <p>I tried this:</p>
  
  <pre><code>// post message to facebook pinnwall
  - (void)postOnWall:(NSString *)message {
  
      NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: message, @"message",nil];
      [[FBRequest request] call:@"facebook.stream.publish" params:params];
  }
  </code></pre>
