在创建framework给他人用时，必须保证我们的framework是没有问题的，这就需要对此framework进行多次调试，如果每次修改framework后，再将此framework导出并添加到测试工程的话，就太麻烦了。因此我们最好能将此测试工程和这个framework放在一起进行调试，这就不得不提到workspace了，他可以管理多个工程，也可以将工程和framework打包前的源码进行联编。

1、xcode多个子工程联合编联开发sdk
1》创建workspace MyFriWorkspace.xcworkspace
2》在此workspace下创建两个工程 MyMainProject及MySecMainProject中，两个工程的Add to:和Group:都选择MyFriWorkspace 这时已经可以在一个workspace中管理两个工程了
3》建自定义sdk工程添加到workspace进行联编（添加进去两个工程能进行互相联编,最常见的应用就是静态库的开发。）
3.1》File - New - Project - Cocoa Touch Static Library 创建静态库MyFriSDK（按上边创建Project的方式创建sdk）（这里主要是MyMainProject与MyFriSDK的联编）
3.2》在sdk中声明实现方法MyFirstSDKAction
3.3》实现MyMainProject与MyFriSDK的联编：选中MyMainProject -》General -》 点击Linked Frameworks and Libraries + -》选中Workspace/libMyFriSDK.a
3.4》在build Setting -》Libary Search Paths和User Header Search Paths 添加sdk路径/Users/yangyangzi/Desktop/Task/静态库组件化/MyFriWorkspace/MyFriSDK （按照相同方法制作framework时，只在User Header Search Paths 添加sdk路径）
3.5》在MyMainProject中调用sdk中方法，选择目标工程-》运行

真机没有上边一堆，直接打印：MyFirstSDKActionMyFirstSDKAction
注：framework静态库的制作也是这个流程
2、查看.a 支持的架构: lipo -info +.a路径
查看.framework支持的架构：lipo -info + xxx.framework/xxxxFramework 如下图：
