xcode4的环境变量,Build Settings参数,workspace及联编设置

一、xcode4中的环境变量

$(BUILT_PRODUCTS_DIR)

build成功后的,最终产品路径--可以在Build Settings参数的Per-configuration Build Products Path项里设置

$(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

 

其他:

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

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

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

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

 

iphoneos5.0下的编译脚本:

xcodebuild -project "UtilLib.xcodeproj" -configuration "Debug" -target "UtilLib" -sdk "iphoneos5.0" -arch "armv6 armv7" build RUN_CLANG_STATIC_ANALYZER=NO  $(BUILD_DIR)="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}"

 

iphonesimulator5.0下的编译脚本:

xcodebuild -project "UtilLib.xcodeproj" -configuration "Debug" -target "UtilLib" -sdk "iphonesimulator5.0" -arch "i386" build RUN_CLANG_STATIC_ANALYZER=NO $(BUILD_DIR)="${BUILD_DIR}"  BUILD_ROOT="${BUILD_ROOT}"

加上下面一句表示输出到文件:

> "${BUILD_ROOT}.build_output"

 

lipo脚本工具:合并iPhone模拟器和真机的静态类库,生成通用库

lipo -create -output "${CREATING_UNIVERSAL_DIR}/${EXECUTABLE_NAME}" "${CURRENTCONFIG_DEVICE_DIR}/${EXECUTABLE_NAME}"         "${CURRENTCONFIG_SIMULATOR_DIR}/${EXECUTABLE_NAME}"

意思是:把"${CURRENTCONFIG_DEVICE_DIR}目录下的.a文件,和${CURRENTCONFIG_SIMULATOR_DIR}目录下的.a文件合并,

在${CREATING_UNIVERSAL_DIR}目录下,生成两个设备都通用的静态库,

例如:lipo -create -output xy.a x.a y.a

 

二、xcode4中build Settings常见参数解析

1.Installation Directory:安装路径

静态库编译时,在Build Settings中Installation Directory设置“$(BUILT_PRODUCTS_DIR)”

Skip Install设为YES

Installation Directory默认为/usr/local/lib

因为Build Location默认时,.a文件会放在很长(比如:/Users/xxx/Library/Developer/Xcode/DerivedData/xxxProgram

dalrvzehhtesxdfqhxixzafvddwe/Build/Products/Debug-iPhoneos)的路径下,或是我们target指定的路径

Skip Install如果是NO,可能会被安装到默认路径/usr/local/lib

2.Public Headers Folder Path:对外公开头文件路径

设为“include”(具体的头文件路径为:$(BUILT_PRODUCTS_DIR)/include/xx.h)

在最终文件.a同级目录下生成一个include目录

默认:/usr/local/include

Public Headers Folder Path这个路径就是使用这lib的某工程需要依赖的外部头文件.导入这路径后,#include/import "xx.h"才能看到

3.User Header Search Paths:依赖的外部头文件搜索路径

设置为“$(BUILT_PRODUCTS_DIR)/include”

和2中路径对应

4.Per-configuration Build Products Path:最终文件路径

比如设为“../app”,就会在工程文件.xcodeproj上一层目录下的app目录里,创建最终文件

默认为$(BUILD_DIR)/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME) 

等于$(BUILT_PRODUCTS_DIR)

5.Per-configuration Intermediate Build Files Path:临时中间文件路径

默认为:$(PROJECT_TEMP_DIR)/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)

6.Code Signing Identity:真机调试的证书选择

选一个和Bundle identifier相对应的证书

Library Search Paths:库搜索路径

Architectures:架构,设为 armv6 或 armv7

Valid Architectures:应用框架,可以设为 armv6、 armv7 或i386

Product Name:工程文件名,默认为$(TARGET_NAME)

Info.plist File:info文件路径

Build Variants:默认为normal

Other Linker Flags:其他链接标签

设为“-ObjC”

当导入的静态库使用了类别,需要设为-ObjC

iOS Deployment Target:ios部署对象

比如可以选择设为,ios3到ios5的一种版本

Prefix Header:预编头文件(比如:UtilLib/UtilLib-Prefix.pch)

Precompile Prefix Header:设为“Yes”,表示允许加入预编译头

 

三、workspace(工作区)

作用:管理多个工程(project),多工程联编

 

四、workspace多工程联编设置

一、

1.新建一个静态库工程,比如UtilLib,并生成UtilLib.h和UtilLib.m文件

2.选中需要公开的头文件,

把右侧栏的Target Membership中设置为public

或则,选中工程目录target的Build Phases标签的copy headers项,在public中添加要公开的头文件

3.Architectures设为:armv6 armv7

4.Valid Architectures设为:armv6 armv7 i386

5.Build Products Path设为:$(SRCROOT)/../build

6.Per-configuration Build Products Path设为:

$(SRCROOT)/../build/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)

7.Per-configuration Intermediate Build Files Path设为:

$(SRCROOT)/../build/$(TARGET_NAME).build/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)

8.设置安装路径:Installation Directory项

9.设置对外公开的头文件路径:Public Headers Folder Path项


10.为静态库添加依赖的shell脚本

选中工程目录target的Build Phases标签,点击由下角的Add Build Phase按钮

在弹出的菜单里选择Add run script项,然后页面中会多出一个Run Script项

在黑框里填写"$SRCROOT/mergeArmSymbols.sh"

建立对此脚本的依赖(编译静态库的后会运行此脚本)

如果编译时设备选的是iphone simulator:

则此脚本会在对应iphone device的产品目录Debug-iphoneos中,生成对device有用的.a静态库,

相反,如果设备选的是iphone device:

则此脚本会在对应iphone simulator的产品目录Debug-iphoneos中,生成对simulator有用的.a静态库

最后,此脚本调用lipo工具,把本工程生成静态库与此脚本生成的静态库合并,生成simulator和device都通用的.a文件

 

11.具体bash shell脚本如下

mergeArmSymbols.sh

下载右边的图片,然后把后缀改为.sh(其实就是上面的脚本,因为博客园只能上传图片)

静态库编译后的目录结构如下:

 

二、 

1.新建主工程,比如Nuno,添加对静态库的依赖

点击工程,在Build Phases标签的Link Binary With Libraries项中点击加号添加UtilLib.a库

选中上面的红色项,在右边栏的Location选Relative to Project,把值设为../libs/libUtilLib.a

2.设置主工程依赖的外部头文件路径:User Header Search Paths项

$(SRCROOT)/../include

3.设置Header Search Paths为:$(SRCROOT)/../include

4.设置Library Search Paths为:$(SRCROOT)/../libs

编译运行即可实现联编 

 

(备注:选择模拟器iphone 5.0 simulator,编译静态库的时,最终文件会在Debug-iphonesimulator,就算成功.a文件还是红色,

这是可能是xcode的bug,不会自动切换路径

因为$(BUILT_PRODUCTS_DIR)所指的位置,是build/Debug-iphonesos,不是包含最终.a文件的Debug-iphonesimulator;

选择ios Device,编译成的最终文件才在build/Debug-iphonesos下,.a文件变成非红色

所有得用mergeArmSymbols.sh脚本来解决)
