Question

这是我关于stackoverflow的第一个问题。干杯！

请从以下链接查看我的代码。我将appdelegate.h，appdelegate.m，viewcotroller.h和.m复制粘贴到文本文档中以供查看。

http://www.mediafire.com/view/85614p44t8eiqif/HomePageViewController.rtf

我将在下面详细解释我的问题。

我正在尝试通过代码以较小的比例重新创建UICatalogue。我是一名应用开发实习生。这是我到目前为止所做的。

请记住，我对Xcode和Objective-C的了解非常有限。我正在使用Xcode 5.1.1

我在AppDelegate.h中为主页视图控制器“HomePageViewController”创建了一个实例变量（HPVC）
我已将此HPVC设置为rootviewcontroller。
声明并定义了一些实例变量。

*但到目前为止，我已经陷入了一个循环中。

我知道导入已经在循环中结束了。但我无法解决它。

请检查一下并给我一个答案。我可以开始我的项目如果我能清除这个障碍。

以下是错误的屏幕截图

一切都是正确的，但你忘了在app delegate.m类上导入#import“HomePageViewController.h”

Xcode错误 - 未知类型名称＆＃39; home＆＃39;
