在iOS 6.1上使用social.h功能时输入功能失效

问题描述：

我一直在升级我的应用程序以同时使用FB和Twitter发布......我已经从原始的twitter功能升级，但现在当FBSheet和Twitter表格出现时我发布消息后，应用程序失去焦点，我无法再访问它下面的屏幕。以下是我对这些帖子的陈述声明......我找不到任何明显的东西。在iOS 6.1上使用social.h功能时输入功能失效

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

    }

     faceBookSheet=nil; 
    } 
     break; 

    default: 
    { 
     // We show this Alert if there is no Twitter Enablement 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Quorum Reached" message:message delegate:self cancelButtonTitle:@"Okay" otherButtonTitles:nil]; 
     [alert show]; 
    } 
     break; 
}

有什么建议吗？

好吧。我已经能够清理代码很多..（甚至切换回到一组简单的If语句），只有当Twitter和Facebook都处于活动状态时才会出现问题。似乎Twitter发布如此之快，并交叉发布到我的帐户到Facebook ...在这一点上，我得到了屏幕锁定。 – 2013-05-05 20:43:41

确定..我发现，我已经重复行 tweetSheet=[SLComposeViewController composeViewControllerForServiceType: SLServiceTypeTwitter]; 所以这是造成问题的原因...
