写脚本打包的好处就不多说了，我前面也有写相关的博客介绍，为了以后换了项目方便，我把脚本贴出来，做个记录，以后稍作修改，就可以复用。
项目目录：

目录结构.png

同时打包脚本.png

同时打iOS和Android包并上传

测试包
./pack.sh debug
预生产
./pack.sh pre
正式包
./pack.sh release

当前目录./pack.sh的代码

cd android
./pack.sh $1
cd ../ios
./pack.sh $1

只打iOS或者Android包并上传

进入ios或者android目录

测试包
./pack.sh debug
预生产
./pack.sh pre
正式包
./pack.sh release

ios 目录下./pack.sh的代码

知识点：

xcodebuild打包
gradle打包
shell脚本
这里主要用到的shell命令就是参数的传递,内容的替换，点击这里学习下
