在iOS 6.1上使用social.h功能時輸入功能失效

我一直在升級我的應用程序以同時使用FB和Twitter發佈......我已經從原始的twitter功能升級，但現在當FBSheet和Twitter表格出現時我發佈消息後，應用程序失去焦點，我無法再訪問它下面的屏幕。以下是我對這些帖子的陳述聲明......我找不到任何明顯的東西。在iOS 6.1上使用social.h功能時輸入功能失效

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

switch (social_status) { 
    case kTwitterOn:{ 

     SLComposeViewController *tweetSheet =[[SLComposeViewController alloc] init]; 
     // Sets viewcontroller to twitter type

     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; 
}

有什麼建議嗎？

好吧。我已經能夠清理代碼很多..（甚至切換回到一組簡單的If語句），只有當Twitter和Facebook都處於活動狀態時纔會出現問題。似乎Twitter發佈如此之快，並交叉發佈到我的帳戶到Facebook ...在這一點上，我得到了屏幕鎖定。 – 2013-05-05 20:43:41

確定..我發現，我已經重複行 tweetSheet=[SLComposeViewController composeViewControllerForServiceType: SLServiceTypeTwitter]; 所以這是造成問題的原因...
