運行Appdelegate.m的應用程序錯誤（sigabrt錯誤）

我得到一個SIGABRT錯誤，我真的很煩，請你幫助我。我知道錯誤是由應用程序委託中的某些內容引起的。我仔細檢查了代碼，並檢查了故事板，但這裏沒有問題。即使解析正在編譯。運行Appdelegate.m的應用程序錯誤（sigabrt錯誤）

沒有人可以幫你。您需要發佈完整的錯誤。在調試器中運行時會發生崩潰嗎？哪一行代碼導致了這個問題？ – rmaddy 2013-02-22 02:32:00

注意：您應該不會發布您的Parse應用程序ID和客戶端密鑰。我建議你從你的問題中刪除這些。 – rmaddy 2013-02-22 02:33:34

您是否在您的調試方案中啓用了殭屍併爲Objective-C異常添加了斷點？這應該給你更多的信息，瞭解錯誤發生的地點和原因。 – TheEye 2013-02-22 15:34:30

下面的一行代碼是錯誤的

UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;

因爲self.window.rootViewController;只會返回的UIViewController。不是的UITabBarController

正確的代碼

UITabBarController *tabBarController = self.window.rootViewController.tabBarController;

如果根視圖控制器實際上是一個'UITabBarController'，那麼原始代碼行就可以了。 – rmaddy 2013-02-22 02:31:19

哦，我看到...... – 2013-02-22 08:58:45
