在Xcode 项目执行：Run Script 时，则标识：${SYMROOT} . 更改括号类型。

例如：BUILD 号自增，编译完成后自动copy 某文件至目标文件夹等：

cp -R ${BUILD_DIR}/${CONFIGURATION}-iphoneos/XXXX.bundle ${SRCROOT}/../XXXProject/

具体环境变量如下：

$(SYMROOT) = $()/Build/Products

$(BUILD_DIR) = $()/Build/Products

$(BUILD_ROOT) =  $()/Build/Products

这三个变量中的$()不会随着Build Settings参数的设置而改变

相反，以下可以通过设置而改变

$(CONFIGURATION_BUILD_DIR) = $()/Build/Products/Debug-iphonesimulator

$(BUILT_PRODUCTS_DIR) = $()/Build/Products/Debug-iphonesimulator

$(CONFIGURATION_TEMP_DIR) = $()/Build/Intermediates/UtilLib.build/Debug-iphonesimulator

$(TARGET_BUILD_DIR) = $()/Build/Products/Debug-iphonesimulator

$(SDK_NAME) = iphonesimulator5.0

$(PLATFORM_NAME) = iphonesimulator

$(CONFIGURATION) = Debug

$(TARGET_NAME) = UtilLib

$(EXECUTABLE_NAME) = libUtilLib.a 可执行文件名

${IPHONEOS_DEPLOYMENT_TARGET} 5.0

$(ACTION) = build

$(CURRENTCONFIG_SIMULATOR_DIR) 当前模拟器路径 

$(CURRENTCONFIG_DEVICE_DIR) 当前设备路径 

 

$(BUILD_DIR)/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME =

$()/Build/Products/Debug-iphonesimulator

$(PROJECT_TEMP_DIR)/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME) = $()/Build/Intermediates/UtilLib.build/Debug-iphonesimulator

 

自定义变量

${CONFIGURATION}-iphoneos 表示：Debug-iphoneos

${CONFIGURATION}-iphonesimulator 表示：Debug-iphonesimulator

$(CURRENTCONFIG_DEVICE_DIR) = ${SYMROOT}/${CONFIGURATION}-iphoneos

$(CURRENTCONFIG_SIMULATOR_DIR) = ${SYMROOT}/${CONFIGURATION}-iphonesimulator

自定义一个设备无关的路径（用来存放各种架构arm6/arm7/i386输出的产品）

$(CREATING_UNIVERSAL_DIR) = ${SYMROOT}/${CONFIGURATION}-universal

自定义变量代表的值

$(CURRENTCONFIG_DEVICE_DIR) ＝ $()/Build/Products/Debug-iphoneos

$(CURRENTCONFIG_SIMULATOR_DIR) = $()/Build/Products/Debug-iphonesimulator

$(CREATING_UNIVERSAL_DIR) = $()/Build/Products/Debug-universal
