1.new project->framework
2.build setting中设置mach-o type static libraty
3.cd到目录 pod init
4.修改pod pod install
5.重要：.h文件中import所有需要暴露的头文件，否则会报找不到文件
6.编译，真机和模拟器分别编译一份
lipo info /Users/user/xxx/Pods/libMQTTClient/products/libMQTTClient.framework/libMQTTClient 查看两个版本支持的cpu架构
sudo lipo -create /Users/user/Library/Developer/Xcode/DerivedData/libMQTTClient-bxngmnzxnfrtcggfqltcwcrnfagk/Build/Products/Release-iphoneos/libMQTTClient.framework/libMQTTClient /Users/user/Library/Developer/Xcode/DerivedData/libMQTTClient-bxngmnzxnfrtcggfqltcwcrnfagk/Build/Products/Release-iphonesimulator/libMQTTClient.framework/libMQTTClient -output /Users/user/libMQTTClient/products/libMQTTClient
合并架构
7.新建podspec文件
修改git相关参数
git repo push XXX
s.vendored_frameworks = 'products/*.{framework}'
推库
8.pod中引入 pod install使用
