代码中的错误，但无法找出在哪里（价值不导入）

Question

我建立一个基于主视图控制器（CalViewController）做一些数学，然后，有两个视图控制器的应用程序（DrinksViewController & FoodViewController） 。

我建立CalViewController和DrinksViewController但是当我想要复制DrinksViewController建立FoodViewController（使用不同的数据相同视图）的错误出现了：“属性‘bouffon’在类型FoodViewController的对象未找到”。

鉴于在我的foodViewController.h中定义的'bouffon'，然后由CalViewController导入。它适用于'CaloriesDepensees'（来自DrinksViewController的数据），但不适用于'bouffon'。我检查DrinksViewController.h和.m中的每一行，看起来它与FoodViewController.h和.m（显然具有不同的数据）完全相同。

自定义类别&故事板ID也是此视图控制器（在故事板，身份检查器中）的FoodViewController。

非常感谢您的帮助！

这里出现错误， 'bouffon' 不是称为FoodViewController的目的。

研究一些激烈小时后，我想出另一个FoodViewController.m创建和出现在我的Finder中。

所以，只需要检查我的Finder并删除错误的文件。
