Question

我正在构建一个基于主视图控制器（CalViewController）的应用程序来进行数学运算，然后，有两个视图控制器（DrinksViewController＆amp; FoodViewController）。

我构建了CalViewController和DrinksViewController，但是当我想复制DrinksViewController来构建FoodViewController（相同的视图使用不同的数据）时出现了一个错误：在PropertyViewController类型的对象上找不到“Property'buffon'。

然后在我的foodViewController.h中定义'bouffon'，然后由CalViewController导入。它适用于'CaloriesDepensees'（来自DrinksViewController的数据），但不适用于'bouffon'。我检查了DrinksViewController.h和.m中的每一行，它看起来与FoodViewController.h和.m完全相同（显然有不同的数据）。

Custom Class＆amp;故事板ID也是此视图控制器的FoodViewController（在故事板中，身份检查器）。

非常感谢您的帮助！

Answer 1

经过一段时间的研究，我发现另一个FoodViewController.m已经创建并出现在我的Finder中。

因此，只需检查我的Finder并删除错误的文件。

代码中的错误，但无法弄清楚在哪里（值未导入）
