Xcode build setting中的配置或者在xcode环境中运行相关脚本会涉及到各种系统的环境变量，参考Xcode环境变量苹果官方文档，做个记录，便于以后查询，以下只记录部分我个人觉得重要的部分。

可以通过下面图的方式观察具体变量代表的值，TARGET_NAME就是其中一个环境变量。

添加script

build之后可以在，下图提示的位置看到对应的输出，可以看到TARGET_NAME的相应输出，和箭头处的标识符合。

脚本输出观察

以上面截图工程为例，以下部分参数输出仅供参考

TARGET_NAME:XcodeEnvironment

PRODUCT_NAME:XcodeEnvironment

PROJECT_NAME:XcodeEnvironment

EXECUTABLE_NAME:XcodeEnvironment

ACTION:build (有以下值build、clean、install、installhdrs、installsrc)

CONFIGURATION:Debug (有以下值Release、Debug、自定义的configuration名字)

EFFECTIVE_PLATFORM_NAME:-iphonesimulator(有以下值-iphonesimulator、-iphoneos需注意左边有-)

PLATFORM_NAME:iphonesimulator(同上，左边没有-)

INFOPLIST_FILE:XcodeEnvironment/Info.plist

INFOPLIST_PATH:XcodeEnvironment.app/Info.plist
