本文旨在让不会使用Unity的其他人员在简单了解该工具后，可以帮助研发人员搭建Unity中的UI预制体，研发人员稍作调整即可用，以减轻研发人员的工作压力。
一个UI视图的预制体的制作步骤如下：
1.在蓝湖中下载该视图的所有相关切图
2.将下载的切图资源包解压缩后，拖入到Unity中Project窗口的Assets目录中的任一文件夹内
3.选中所有切图，在Inspector窗口修改Texture Type为Sprite类型，并点击右下角的Apply
4.在顶部菜单栏SKFramework中找到LanHu，打开窗口
5.点击浏览按钮选择该视图的切图所在文件夹
6.点击创建，创建一个Canvas画布，也可以选择场景中已有的Canvas
7.添加
点击添加按钮，添加一项UI视图元素
在蓝湖中点击切图的样式信息中的内容即可复制
回到Unity，点击粘贴按钮，将从蓝湖中复制的内容粘贴到对应参数中
8.删除
点击”-“号按钮，可以将该项进行移除
点击清空按钮，可以清空当前所有的配置信息
9.收缩
配置信息过多时，点击收缩按钮，可以关闭所有折叠栏
10.展开
点击展开按钮，可以打开所有折叠栏
11.生成
点击生成后，工具会根据填写的配置信息，在切图所在文件夹中加载指定切图，并将其设置到指定位置、设置指定大小，最终将生成的UI视图创建为prefab预制体。
随着预制体的生成，工具还会将该视图的所有配置信息以资产的形式保存下来
12.导入
当想要修改一个UI视图的某一元素时，点击导入按钮，将该视图的配置资产文件进行导入，修改配置内容后重新生成即可。
13.预览生成的UI视图
打开Scene窗口中的2D选项
在Hierarchy窗口找到Canvas中的UI视图，双击聚焦查看
