静态库架构合并，静态库抽离架构，静态库去除.o文件脚本

新建父文件夹，下面新建文件夹os里面放libPingAn.a的真机包,simulator里面放libPingAn.a的模拟器包,shell文件命名release。如果改名，脚本文件也要改名。
shell文件内容:

#!/bin/bash
lipo -extract_family armv7 -output os/libPingAn_arm.a os/libPingAn.a
lipo os/libPingAn.a -thin arm64 -output os/libPingAn_arm64.a
lipo -extract_family i386 -output simulator/libPingAn_i386.a simulator/libPingAn.a
lipo -extract_family x86_64 -output simulator/libPingAn_x86_64.a simulator/libPingAn.a
echo "extract libs finish."
wait

cp simulator/libPingAn_i386.a i386/libPingAn_i386.a
echo "copy file OK."

echo "done!!"

# print('remove i386.')
# lipo -remove i386 libPingAn.a -o libPingAn.a

# print('查看arm7中包含的.o文件')
# ar -t libPingAn_arm7

arm64等文件夹里面是静态库说包含的.o文件，因项目需要里面，去掉了一些三方的.o文件，可适当去除。
使用：
终端 cd 到父目录，ls看到release.sh,./启动脚本。
仅供参考，实际使用中，自己修改即可。

查询支持哪些指令集：
lipo -info /user/pingan.a

附一：
各架构对应机型：
arm64e:iPhone XS\XR\XS Max
arm64：iPhone6s | iphone6s plus｜iPhone6｜ iPhone6 plus｜iPhone5S | iPad Air｜ iPad mini2(iPad mini with Retina Display)
armv7s：iPhone5｜iPhone5C｜iPad4(iPad with Retina Display)
armv7：iPhone4｜iPhone4S｜iPad｜iPad2｜iPad3(The New iPad)｜iPad mini｜iPod Touch 3G｜iPod Touch4
i386 ：针对intel通用微处理器32位处理器，模拟器32位处理器
x86_64 ：针对x86架构的64位处理器，模拟器64位处理器

附二：（基于之前的改的python版本，shell更简单一些。留着看吧）
python os.system('')可直接调用shell语句，写着练手的。
