一、简单介绍
Unity 工具类，自己整理的一些游戏开发可能用到的模块，单独独立使用，方便游戏开发。
一个简单的UI管理框架管理类，管理各个UIPanel、和UI Widget 元素，只要传一个UIWidget名字即可给对应UIWidget 添加对应事件（按钮、Slider、Drag 、PointerClick 等）或者修改上面的内容（文本、图片等）。
二、什么是 MVC
MVC全名是Model View Controller，是模型(model)－视图(view)－控制器(controller)的缩写，一种软件设计典范，用一种业务逻辑、数据、界面 显示分离的方法组织代码，将业务逻辑聚集到一个部件里面，在改进和个性化定制界面及用户交互的同时，不需要重新编写业务逻辑。MVC被独特的发展起来用于 映射传统的输入、处理和输出功能在一个逻辑的图形化用户界面的结构中。
MVC 框架简单如下图
换种形式的 MVC 业务流程
- Model（模型）是应用程序中用于处理应用程序数据逻辑的部分。 通常模型对象负责在数据库中存取数据。
- View（视图）是应用程序中处理数据显示的部分。 通常视图是依据模型数据创建的。
- Controller（控制器）是应用程序中处理用户交互的部分。 通常控制器负责从视图读取数据，控制用户输入，并向模型发送数据。
三、简单使用说明
1、UIPanel 各个UI面板 继承 UIPanelBase
2、UIPanel 中类似如下通过UI元素的名称进行相关事件绑定，Text 或者 Image.Sprite 更新等等
AddButtonListener(UIWidegetNameString.Button_N,tmpPanelLogic.Button_N);
AddInputFieldValueChangedListener(UIWidegetNameString.InputField_N, tmpPanelLogic.InputField_N);
AddSliderListener(UIWidegetNameString.Slider_N, tmpPanelLogic.Slider_N);
ChangeTextContent(UIWidegetNameString.Text_N, "Test Text_N Click : " + mTmpPanelModel.ClickCount1);
........
3、本案例 TmpPanelModel，TmpPanelLogic，TmpPanel 使用 MVC 将每部分独立成块
4、GameStart 作为程序入口，初始化 UIPanelManager，既可以运行起来整个框架
四、实现原理
1、GameStart 启动 UIPanelManager；
2、UIPanelManager 启动 UIPanelBase；
3、UIPanelBase 获取所有子物件，并且给子物件名称 _N 结尾的添加 UIBehaviour 脚本，并且给子物件名称 _C 结尾的添加 UISubPanelManager脚本；
4、UIBehaviour / UISubPanelManager 把自己注册到 UIPanelManager 字典中；
5、UISubPanelManager 给子物件名称 _S 结尾的添加 UIBehaviour 脚本，并且这里的 UISubPanelManager 管理 _S 子物件 ；
6、各个 UIPanel （继承 UIPanelBase）通过 _N / _S UI Widget 名称 访问该 UI Widget ，添加相关的事件等；
7、UIPanelBase / UIBehaviour / UISubPanelManager 可以根据自己需要扩展更多功能；
8、UIPanelManager 的框架大概如下：
五、注意事项
1、_N，_C, _S 的尾部特征可以根据自己的需要自行设定定义
2、UIPanel 之间的名称一定不一样，且 同一 UIPanel 下的 _N UI Widget 名称一定不能重复，不同 UIPanel 下的 _N UI Widget 名称可重复；
3、_C 的名称一定也不一样 (其实 _C 的管理类似 UIPanel)， 同一 _C 下的 _S UI Widget 名称一定不能重复，不同 _C 下的 _S UI Widget 名称可重复；
六、效果预览
七、实现步骤
1、打开Unity，新建一个空工程
2、在场景中，UI布局，如下图，把对应的要用到的UI Widget 添加 _N，并把 Item 作为可重用的 item，对应下面要用到的UI Widget 添加 _S，同时把 TmpPanel 添加 TmpPanel 脚本，和 Item 一起作为预制体，保存到 工程中，如下图
3、在工程中新建脚本，APP 文件夹中的脚本是不同的应用中涉及到的一些变化较大的脚本，UIFramework 文件夹中的脚本是UI框架中，实际应用变化较小的脚本，是UI的关键脚本
4、把 GameStart 脚本挂载到场景中，是应用的启动脚本，同时Canvas 以作为预制体的 TmpPanel（注意：TmpPanel预制体挂载了TmpPanel脚本） 删除
5、运行场景，效果如上
