Xcode编译App（一）: 编译单个Target

编译单个 Target 过程 (以 AFNetworking 为例子)

转载请注明出处！！！

一、准备工作

Build target AFNetworking of project Pods with configuration Debug

1、CreateBuildDirectory (产品 Products 最终路径: Build/Products)

命令是 builtin-create-build-directory

// 创建 build products 文件夹
CreateBuildDirectory /Users/ocean/Library/Developer/Xcode/DerivedData/MyAppName-eexzhxxmdkygpcfkoprwzzghvpkj/Build/Products (in target: AFNetworking)
    cd /Users/ocean/Desktop/code/iOS/Company/Myway/MyAppName/MyAppName/Pods
    builtin-create-build-directory /Users/ocean/Library/Developer/Xcode/DerivedData/MyAppName-eexzhxxmdkygpcfkoprwzzghvpkj/Build/Products

---

AFNetworking 文件夹内容如下:

$ cd /Users/ocean/Library/Developer/Xcode/DerivedData/MyAppName-eexzhxxmdkygpcfkoprwzzghvpkj/Build/Products/Debug-iphonesimulator/AFNetworking 
$ tree
.
└── libAFNetworking.a

libAFNetworking.a就是最终生成的静态库

2、CreateBuildDirectory (产品 Products 中间文件路径: Build/Intermediates.noindexs)

命令是 builtin-create-build-directory

// 创建 build products 临时的文件夹
CreateBuildDirectory /Users/ocean/Library/Developer/Xcode/DerivedData/MyAppName-eexzhxxmdkygpcfkoprwzzghvpkj/Build/Intermediates.noindex (in target: AFNetworking)
    cd /Users/ocean/Desktop/code/iOS/Company/Myway/MyAppName/MyAppName/Pods
    builtin-create-build-directory /Users/ocean/Library/Developer/Xcode/DerivedData/MyAppName-eexzhxxmdkygpcfkoprwzzghvpkj/Build/Intermediates.noindex

---

AFNetworking.build 内容如下:

$ cd /Users/ocean/Library/Developer/Xcode/DerivedData/MyAppName-eexzhxxmdkygpcfkoprwzzghvpkj/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/AFNetworking.build 
$ tree

• AFNetworking.LinkFileList: 存储的生成.a静态库所需要链接的对象文件.o
• 每一个类都三个文件 .d、.dia、.o

补充介绍：每一个类都会生成 .d .dia .o 这三个文件

• .d: 表示这个类所依赖的其他类，即使用import导入的头文件，会自动寻找所有的依赖头文件，包含多级依赖 (a依赖b，b又依赖c，那么最终a也会依赖c)
• .dia: 是diagnose的简写，就是诊断的意思，我们在Xcode写的源代码，经过编译的时候有时候会生成一些警告信息，都是放到这里面的
• .o: 对象文件，.m经过编译生成.o文件，用来链接到静态库/可执行文件中

UIWebView+AFNetworking.d: 打开内容如下:

补充 ，使用 clang 来编译文件的一些命令如下
