如何通过隐藏SLComposeViewController * tweetSheettweet实例在Twitter上发布

我的应用需要支持iOS 5。

我有我的自定义用户界面，用户可以inputtweet消息，当他按下后button，它应该张贴消息Twitter。

我已经编写了通过SLComposeViewController * tweetSheet实例发布的代码，但在这种情况下，我不能直接按tweetSheet提供的发送button，

[self presentViewController:tweetSheet animated:YES completion:nil]; 

是否有可能绕过这个演示文稿，并设置文本消息，并张贴到Twitter通过我的自定义用户界面有postbutton？

  if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) { SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; tweetSheet.completionHandler = ^(SLComposeViewControllerResult result) { switch(result) { // This means the user cancelled without sending the Tweet case SLComposeViewControllerResultCancelled: NSLog(@"Tweet message was cancelled"); break; // This means the user hit 'Send' case SLComposeViewControllerResultDone: NSLog(@"Done pressed successfully"); break; } // dismiss the Tweet Sheet dispatch_async(dispatch_get_main_queue(), ^{ [self dismissViewControllerAnimated:NO completion:^{ NSLog(@"Tweet Sheet has been dismissed."); }]; }); }; [tweetSheet setInitialText:self.textViewPostedText.text]; [self presentViewController:tweetSheet animated:YES completion:nil]; } 

如果用户有多个Twitter帐户，如何给select选项？
