title: Post notification with sender and object
body: <p>I cannot seem to find out how to post a notification with an object and a sender.</p>
  
  <p>I can post a notification with a name, sender and user info. See:</p>
  
  <pre><code>- (void)postNotificationName:(NSString *)notificationName
                        object:(id)notificationSender
                      userInfo:(NSDictionary *)userInfo
  </code></pre>
  
  <p>And I can post a NSNotification with an object, but not link an sender to it:</p>
  
  <pre><code>NSNotification *notification = [NSNotification notificationWithName:name
                                                               object:someObject];
  [[NSNotificationCenter defaultCenter] postNotification:notification];
  </code></pre>
  
  <p>Can anybody tell me how to post a notification with (a) a object and (b) a sender reference?</p>
