在IOS-5中獲取Twitter帳戶列表並用TWTweetComposeViewController將其用戶

我正在使用Twitter與IOS-5集成。我用這個蘋果提供的tweeting應用程序。我爲此使用了TWTweetComposeViewController。在IOS-5中獲取Twitter帳戶列表並用TWTweetComposeViewController將其用戶

但是，如果我有超過2個Twitter帳戶。它每次都得到我的第一個帳戶。但我希望顯示給我的不同帳戶的列表，然後當我選擇一個帳戶，然後我可以將它與TWTweetComposeViewController一起使用。我想展現像波紋圖像來源：

我已經使用這個代碼「用戶名」：

- (IBAction)sendEasyTweet:(id)sender { 
// Set up the built-in twitter composition view controller. 
TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init]; 

// Set the initial tweet text. See the framework for additional properties that can be set. 
[tweetViewController setInitialText:@"Hello. This is a tweet."]; 
[tweetViewController addImage:[UIImage imageNamed:@"Icon.png"]]; 


// Create the completion handler block. 
[tweetViewController setCompletionHandler:^(TWTweetComposeViewControllerResult result) { 
    NSString *output; 

    switch (result) { 
     case TWTweetComposeViewControllerResultCancelled: 
      // The cancel button was tapped. 
      output = @"Tweet cancelled."; 
      break; 
     case TWTweetComposeViewControllerResultDone: 
      // The tweet was sent. 
      output = @"Tweet done."; 
      break; 
     default: 
      break; 
    } 

    [self performSelectorOnMainThread:@selector(displayText:) withObject:output waitUntilDone:NO]; 

    // Dismiss the tweet composition view controller. 
    [self dismissModalViewControllerAnimated:YES]; 
}]; 

// Present the tweet composition view controller modally. 
[self presentModalViewController:tweetViewController animated:YES];

}
