之前已经有几篇文章写打包AssetBundle，但毕竟没有实际在项目中写过都写的比较浅。刚好最近项目更新Unity5.5.2就顺便由我来更新ui打包流程
这里就把这次的经验写一下
这里还是稍微解释一下打包的基本目的：
打包ui就是把你做的界面打包出来成assetbundle包，讲道理你就把每个界面打成bundle包在游戏中你就可以直接加载来用，但是这样子的话你的每个bundle包就会非常的大，为什么呢，是因为这样子每个界面的bundle包里都包含这个界面用到的字体，贴图atlas，texture，shader还可以有你自己使用的动态组件。
这样子你的同一份资源都复制了很多份出来。
当然不能这样子做
所以我们就需要把这些atlas，font给剥离开来独立打包
不过新的打包方式让我们不用再手动剥离开来这些东西，也就是没有了剥离之后要重新引用的烦恼。
所要做的事就是把需要打包的东西改一改它的AssetBudnle名再一起build就好了
总的来说，就是把一个ui界面的下的atlas，font，texture，component记录下来，
通过修改这个ui.prefab，atlas，font，texture，compoent的预制件的bundle名，最后调一下打包函数就可以了
（有的项目texutre和shader是有自己写的管理类来加载，需要把引用置空的，这时候就需要实例ui.prefab，并把引用赋空，拷贝一份到另外一个文件夹中）
上一篇ui打包文章
http://blog.csdn.net/chrisfxs/article/details/55046339
而这次的流程是
1.清理数据，建立文件夹
2.遍历所有文件夹下的ui界面prefab
3.遍历所有prefab下的compoent（动态组件）
4.找出所有的资源（如atlas，font）用个list记录下来
5.修改这些资源和这个ui.prefab的assetbundle名
6.build
补充一点！
游戏加载assetbundle的时候要先加载atlas，font这些资源，最后加载ui资源
这样才能保证引用没有丢失
