环境：
xcode9
mac os 10.13
1、下载boost库并解压
2、cd到解压后的文件包内，执行 sh bootstrap.sh（解压后会得到这个脚本文件）。
3、执行./b2 编译整个库。
4、经过一段时间编译后，得到编译后的头文件和库文件。
5、运行 sudo ./b2 install 命令 将编译后的库安装到系统默认路径/usr/local/include下
6、这时候得到的库文件可能只是X86_64此类模拟器架构运行的库，如果需要真机库需要在第3步之后按照实际情况运行以下脚本。sh myBuildBoost.sh
7、运行后会编译出需要架构的库文件，直接将编译完成之后的库文件复制到系统目录下即可。
8、xcode调试，依次在header Search path 和 library search path后添加头文件和库文件路径/usr/local/include /usr/local/lib
9、在build phases ->link binaru with libray中添加需要的库文件。
10、在实际真机运行中可能会要求关闭bitcode，关闭即可运行。
