一、为什么要使用cocoapods-packager
为了解决SDK中引入的第三方库和接入项目中引入的第三方库冲突问题。
CocoaPods Packager在打包静态库的过程中会自动将引入的第三方库的符号加上前缀（Name-Mangling）。如果我们引入的第三方库也是一个静态库，那这个自动改名就无法生效了。
- 安装 cocoapods-packager
sudo gem install cocoapods-packager
二、制作pod库
1.cd到你想存放代码的目录
2.创建pod库
pod lib create FGCallKit
如果报一下错误fatal: unable to access 'https://github.com/CocoaPods/pod-template.git/': HTTP/2 stream 1 was not closed cleanly before end of the underlying stream
就执行
git config --global http.version HTTP/1.1
过程中会有一个问题页面，可参考如下的填写：
# 平台
What platform do you want to use?? [ iOS / macOS ]
> iOS
# 语言
What language do you want to use?? [ Swift / ObjC ]
> ObjC
# 是否需要创建demo，一般选择Yes
Would you like to include a demo application with your library? [ Yes / No ]
> Yes
# 测试框架
Which testing frameworks will you use? [ Specta / Kiwi / None ]
> None
# 视图测试
Would you like to do view based testing? [ Yes / No ]
> No
# 类前缀
What is your class prefix?
> FG
三、打包静态库
1.打包前先做一下验证
cd到工程所在的目录下
# 本地验证
pod lib lint FGCallKit.podspec --allow-warnings --use-libraries --verbose
# 远程验证（可选）
pod spec lint FGCallKit.podspec --allow-warnings --use-libraries --verbose
2.提交代码、添加tag
add .
git commit -m '0.1.0'
# 这里的tag必须和.podspec文件中配置的s.version一致
git tag 0.1.0
git push origin 0.1.0
3.打包成.framework
pod package FGCallKit.podspec --force --no-mangle
这里的参数说明：
// 强制覆盖之前生成的文件
--force
// 不使用name-mangling技术，也就是自动改类名等符号
--no-mangle
// 生成静态的framework
--embedded
// 生成静态.a
--library
// 生成动态framework
--dynamic
// 使用本地文件
--local
// 生成动态framework的时候需要这个BundleId来签名
--bundle-identifier
// 不包含依赖的符号表，也就是不把依赖的第三方库打包进去
--exclude-deps
// 生成debug还是release的库，默认是release
--configuration=Release
// 如果你的pod库有subspec，那么加上这个命名表示只给某个或几个subspec生成二进制库
--subspecs=subspec1,subspec2
// 默认是CocoaPods的Specs仓库，如果你的项目有私有的source，就可以通过这个参数来设置
--spec-sources=private,https://github.com/CocoaPods/Specs.git
如果报错：
error: The armv7 architecture is deprecated. You should update your ARCHS build setting to remove the armv7 architecture. (in target 'Pods-packager' from project 'Pods')`
参考Cocoapods Packager + Xcode14 适配 -
其他错误：
- 错误1
[!] The 'Pods-XXX' target has transitive dependencies that include statically linked binaries: (/Users/...)
解决：在 podspec文件中添加
s.static_framework = true
- 错误2
fatal error: /Applications/Xcode 12.0.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: Pods/build/package.a and Pods/build-sim/package.a have the same architectures (arm64) and can't be in the same fat output file
解决：前往文件夹/Library/Ruby/Gems/2.6.0/gems/cocoapods-packager-1.5.0/lib/cocoapods-packager，找到pod_utils.rb代开，在33行添加以下代码
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
- 错误3
[!] Unable to find a specification for `xxx` depended upon by `xxx`
You have either:
* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
* mistyped the name or version.
* not added the source repo that hosts the Podspec to your Podfile.
解决：更新一下repo
pod repo update
// 或
pod install --repo-update
- 错误4
[!] The 'xxx' target has transitive dependencies that include statically linked binaries: (/../../xxx.framework)
解决：在当前xxx.podspec中添加s.static_framework = true;
- 错误5
在pod trunk push --allow-warnings时出现一下错误
- NOTE | [iOS] xcodebuild: Pods.xcodeproj: warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 10.0, but the range of supported deployment target versions is 11.0 to 16.2.99. (in target 'FGChatKit-pod' from project 'Pods')
解决：就在.podspec中添加一下代码
# 排除arm64架构
s.pod_target_xcconfig = {
'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64'
}
s.user_target_xcconfig = {
'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64'
}
