xcode环境变量

原文：http://www.2cto.com/kf/201302/191830.html

$(BUILT_PRODUCTS_DIR)

build成功后的，最终产品路径－－即build/Debug-iphoneos路径下
$(TARGET_NAME)
目标工程名称
$(SRCROOT)
工程文件（比如Nuno.xcodeproj）的路径 
$(CURRENT_PROJECT_VERSION)
当前工程版本号
当编译静态库，设备选模拟器(iPhone 5.0 Simulator)，未设置任何Build Settings参数时，默认的基础路径：
 
/Users/xxx/Library/Developer/Xcode/DerivedData/xxxWorkspace-caepeadwrerdcrftijaolkkagbjf
 
下面用$()代替上面一长串东东
 
$(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www.2cto.com
 
$(CURRENTCONFIG_DEVICE_DIR) ＝ $()/Build/Products/Debug-iphoneos
 
$(CURRENTCONFIG_SIMULATOR_DIR) = $()/Build/Products/Debug-iphonesimulator
 
$(CREATING_UNIVERSAL_DIR) = $()/Build/Products/Debug-universal
