Xcode6内置环境变量(Build Setting Macros)

（1）查看环境变量宏

新建一个HelloWorld项目在桌面 ,cd Desktop/HelloWorld/

命令行进入HelloWorld工程目录，执行xcodebuild命令并带上“-showBuildSettings”参数：

$ xcodebuild -project HelloWorld.xcodeproj -target HelloWorld -configuration Debug -showBuildSettings > buildSettings.txt

则buildSettings.txt中保存了Build settings for action build and target "HelloWorld”，其中dump了所有的环境变量。

（2）buildSettings.txt内容 标红的为常见变量
