由於SIGABRT發生，我的應用程序崩潰

我使用Apple的示例文件的'Detail - Master Application'。由於SIGABRT發生，我的應用程序崩潰

我編輯了它的'Main-iPhone.storyboard'就像這張圖片。

Main-iPhone.storyboard

而且這個錯誤發生在我的應用程序。

你的崩潰日誌給你答案：

2013-12-14 15:13:12.963 IFST[2448:70b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITabBarController topViewController]: unrecognized selector sent to instance 0x8a6c290'

某處你發送topViewController標籤欄控制器。這不是導航控制器，所以這種方法是不合適的。也許selectedViewController是你正在尋找的。

謝謝。但我沒有編輯它的代碼。 – Rukkora

我該如何解決？ – Rukkora

您應該重新審視將您的導航控制器添加到故事板的方式。我認爲問題在於此。 – Alexander
