警告詳細告訴你缺什麼。 –

我們需要看到頭文件。不完整的實現是由於您沒有實現您在頭文件中聲明的方法或者您符合的必需協議方法。 – Joe

我從來沒有看到這個細節。它發生在我在標題中定義一個方法並忘記實現它的時候。 –

您還沒有實現在.m文件兩種方法（如果我不讀書是很糟糕）：

-(UIView *)headerView; 
-(IBAction)toggleEditingMode:(id)sender;

這就是爲什麼你會收到警告。

在任何情況下，在你的構建結果窗口中，右鍵，你看到包含數字的黃色圖標警告時，您可以點擊黃色圖標和更多的信息將出現正是細節你在你的執行缺少哪些方法文件。

固定它;非常感謝你！ – pdenlinger

您不會出現已實現了以下兩種方法：

-(UIView *)headerView; 
-(IBAction)toggleEditingMode:(id)sender;
