这种框架是通过加载编写好的面板Json信息的方式去实现的

例如如下图的游戏主界面中，当点击任务面板时其余的按钮都无法交互，当关闭了任务面板后其余的按钮恢复可交互行为

一：创建预制体

创建所需的所有面板，把他们都拖到Resources文件夹下成为预制体

二：创建存储不同面板信息的Json文件

[	{		"panelType": "Main",		"panelPath": "Prefabs/UI_Main"	},	{		"panelType": "Task",		"panelPath": "Prefabs/UI_Task"	},	{		"panelType": "Knapsack",		"panelPath": "Prefabs/UI_Knapsack"	},	{		"panelType": "Battle",		"panelPath": "Prefabs/UI_Battle"	},	{		"panelType": "Skill",		"panelPath": "Prefabs/UI_Skill"	},	{		"panelType": "Shop",		"panelPath": "Prefabs/UI_Shop"	},	{		"panelType": "Setting",		"panelPath": "Prefabs/UI_Setting"	},	{		"panelType": "ItemMessage",		"panelPath": "Prefabs/UI_ItemMessage"	}]

三：创建面板类型的枚举类

public enum PanelType{    Main,    Task,    Knapsack,    Battle,    Skill,    Shop,    Setting,    ItemMessage,}

四：编写UIManager管理类

——解析面板信息的Json文件，将面板类型和面板预制体路径存入一个字典里，字典的键是面板类型，值是面板预制体的路径

//存储每个UI信息的字典private Dictionary
   
     uiInfoDict = new Dictionary
    
     ();/// 
     
/// 解析Json/// 
private void ParseJson(){    TextAsset ta = Resources.Load
     
      ("UIPanelInfo");    JSONObject j = new JSONObject(ta.text);    foreach (var temp in j.list)    {        PanelType panelType = (PanelType)Enum.Parse(typeof(PanelType), temp["panelType"].str);        string panelPath = temp["panelPath"].str;        uiInfoDict.Add(panelType, panelPath);    }}
