问题描述
我不是一个白痴,但头文件让我感觉像一个有时。我有什么可能是一个过于复杂的设置,有一个错误,我不能解决。
I am not an idiot, but header files make me feel like one sometimes. I have what is probably an overly-complicated set-up that has an error that I cannot resolve. Here it is in about as simple as detail as I can make it....
- 我有一个Controller类,它包含一个Model类。
- 我有一个Scene类来捕获动作并与Controller通信。
- 我有一个Layer类,
- Scene类包含仅用于输出的Layer类。
- 场景必须包含由Cocos2D框架确定的图层。 li>
- 特定的Scene类派生自一个保存对Controller类的引用的RootScene类。
- 特定的Layer类派生自一个RootLayer类,
- I have a Controller class that contains a Model class.
- I have a Scene class to capture actions and communicates with the Controller.
- I have a Layer class that talks with the Model class to output the state of the Model.
- The Scene class contains Layer class solely for output.
- Scenes must hold Layers as determined by the Cocos2D framework.
- Specific Scene classes derive from a RootScene class that holds the reference to the Controller class.
- Specific Layer classes derive from a RootLayer class that holds the reference to the Model class.
- The Controller is responsible for creating Scenes and Scenes are responsible for creating Layers.
问题出在制作图层并将控制器的模型传递给图层的模型(在 AScene.m
中)。我得到请求成员'模型'在不结构或联合的东西。铸造不工作,我不知道如何允许这些类彼此交谈。我认为部分问题可能是Controller类包含Model类。
The problem comes when making a Layer and passing the Controller's Model to the Layer's Model (in AScene.m
). I get the "Request for member 'Model' in something not a stucture or union". Casting doesn't work, and I'm at a loss for how to allow these classes to talk with each other. I think part of the problem might be that Controller class contains the Model class.

推荐答案
您的实施 AScene
不会 #import
控制器
的标题。
Your implementation of AScene
does not #import
the header of Controller
.
编辑: 。
在AScene.m中添加:
In AScene.m add:
#import "Controller.h"
