在之前的文章中提到使用3DS支付最终是要下载源码编译得到MPGSDK.framework的。
常规操作，打开MPGSDK.xcodeproj工程。
1、编辑配置将debug改为release
2、选中Any iOS Divce
3、然后command+B
4、再去编译文件Release-iphoneos目录找到MPGSDK.framework，这就是真机库。
WX20210923-145825@2x.png
5、重复上面的步骤，将第2步选中一个模拟器，需要把arm64 排除在外。
build settings->excluded architectures 加入arm64架构,
这是把arm64 排除在外，这样到处的framework 用lipo -info 查询是不包含arm64
得到了Release-iphonesimulator文件夹中的MPGSDK.framework，这就是模拟器库。
xcode 13 生成库路径为：
/Users/adong/Documents/workspace/gateway-ios-sdk/DerivedData/MPGSDK/Build/Products
正确合并方法
1.将Release-iphoneos、Release-iphonesimulator文件复制到A文件夹中。
2.再在A文件夹下创建framework文件夹。
3.将Release-iphoneos中的MPGSDK.framework复制到framework中。
4.使用如下命令进行合并。
lipo -create framework/MPGSDK.framework/MPGSDK Release-iphonesimulator/MPGSDK.framework/MPGSDK -output framework/MPGSDK.framework/MPGSDK
5.再需要把framework中Release-iphonesimulator/MPGSDK.framework/Modules/MPGSDK.swiftmodule的文件全都拷贝到合并的framework/MPGSDK.framework/Modules/MPGSDK.swiftmodule中，如有文件夹同名，将同名下的文件拷贝过去。

将合并之后的库拖到工程，点击运行，断点直接就卡住了。

看到这种错误最开始想到就是配置里的other link flag 使用load_all，其实不用，找到配置中的MPGSDK.framework引用地方将frameworks, Libraries, and Enbedded Content的 Do Not Endbed改为Embed & Sign即可。

这时候就模拟器就可以正常运行了，真机也可以运行了，打包也正常了。
错误合并方法遇到了各种问题
再将这先将真机库拖到A文件中，再将模拟库拖到A文件中，就会得到一个提示是替换还是合并（后面实验得知此方法是错误的，因为使用lipo -info 查看控制台没有输出armv7，后面的报错就对了）。
这时候我们选择合并，就得到了真机和模拟合并的库，
但打包就报了一堆的错误如下：

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
看到这种问题，我是一头两个大！！！！！
找到一条关键信息 ld: symbol(s) not found for architecture armv7，说是没有找到支持armv7的库。
编译真机选的是Any iOS Divce后面还跟着 arm64和armv7的文字呢。没有深研究，我在配置项目里单独输入了armv7同样打了一个包出来了。
使用命令进行合并参照
lipo -create 真机路径 模拟器路径 -output 真机路径
真机路径 /Users/adong/Desktop/test/Release-iphoneos/MPGSDK.framework/MPGSDK
模拟器路径类似
重新将合并了2次的库的拖到工程里，正常打包，但安装到真机，一打开就闪退，连真机运行卡在启动页面就崩了，可能是没有安上面的参照把其他文件合并过来。
