Cocoa touch Can'；不要将Twitter视图添加到场景中

我正在尝试添加一个Twitter视图，这样我就可以看到它正在被调用，并且帐户已连接，但是Twitter表不在那里。。。 它位于

CCScene

（cocos2d）上

而不是显示模态视图的两条线

 if ([TWTweetComposeViewController canSendTweet])  
    {
          //we can log here 
        TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init];

         [tweetViewController setInitialText:@"message"];

         tweetViewController.completionHandler = ^(TWTweetComposeViewControllerResult result)
        {
             if(result == TWTweetComposeViewControllerResultDone)
            {
             } else if(result == TWTweetComposeViewControllerResultCancelled)
            {
             }
            [viewController dismissViewControllerAnimated:YES completion:nil];
        };

        // present view controller
        [[[CCDirector sharedDirector] view] addSubview:viewController.view];
        [viewController presentViewController:tweetViewController animated:YES completion:nil];

    }
    else
    {
         NSLog(@"NO TWITTER  ");
    }

[[CCDirector sharedDirector]presentModalViewController:tweetViewController animated:YES];
