錯誤：預期';'之前在'接口'在Xcode

我試圖通過iPhone的Hello World教程運行，我得到這個錯誤：錯誤：預期';' 'interface'之前我已經檢查過，並且我的文件與教程相同（除了空格），並且我無法弄清楚爲什麼我遇到了這個問題。如有必要，我可以提供代碼。錯誤：預期';'之前在'接口'在Xcode

是的，我會包括代碼 – micmoo 2009-07-11 06:43:26

這是你的問題，你的第一個行：

@class MyViewController

哪裏分號？

不，它沒有解決它... :( – RCIX 2009-07-11 07:07:07

嗯，我一定是在錯誤的文件...這工作！非常感謝 – RCIX 2009-07-11 07:52:39

您可能在同一個文件或包含文件中的struct或enum decl之後忘記了一個分號。

你沒有這個問題，但是當我得到這個錯誤，我在類的實現文件的最開始備用信所產生的錯誤：
