facebook - iOS 6.1 で social.h 関数を使用すると入力機能が失われる

Question

FB と Twitter の両方の投稿を使用するようにアプリをアップグレードしています...元の Twitter 機能からアップグレードしましたが、FBSheet と Twitter シートが表示され、メッセージを投稿すると、アプリがフォーカスを失い、できなくなりました。その下の画面にアクセスします。投稿に対する私のケースステートメントは次のとおりです...明白なものは何も見つかりません。

int social_status = 0;
if (twitterEnabled) {
    social_status=1;
}
if (facebookEnabled) {
    social_status=2;
}
if (twitterEnabled && facebookEnabled) {
    social_status = 3;
}

switch (social_status ) {
    case kTwitterOn:{

        SLComposeViewController *tweetSheet =[[SLComposeViewController alloc] init];
        // Sets viewcontroller to twitter type
        tweetSheet=[SLComposeViewController composeViewControllerForServiceType: SLServiceTypeTwitter];
        SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){
            [tweetSheet dismissViewControllerAnimated:YES completion:nil];

            switch(result){
                case SLComposeViewControllerResultCancelled:
                default:
                {
                    NSLog(@"Cancelled.....");

                }
                    break;
                case SLComposeViewControllerResultDone:
                {
                    NSLog(@"Posted....");
