创建Aggregate来合并模拟器和真机通用的framework

然后在Build Phases下New Run Script Phase创建合并脚本：

# Constants
SF_TARGET_NAME=${PROJECT_NAME}
#自定义的用来存放最后合并的framework
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
#IPHONE_DEVICE_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphoneos
WORKSPACE_NAME=${PROJECT_NAME}.xcworkspace
YO_SCHEME=${PROJECT_NAME}
#clean build是先清除原来的build
xcodebuild -workspace ${WORKSPACE_NAME} -scheme ${YO_SCHEME} -sdk iphonesimulator -configuration"${CONFIGURATION}"clean build
xcodebuild -workspace ${WORKSPACE_NAME} -scheme ${YO_SCHEME} -sdk iphoneos -configuration"${CONFIGURATION}"clean build
# build project
#xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}" -configuration "${CONFIGURATION}" -sdk iphoneos BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}" CONFIGURATION_BUILD_DIR="${IPHONE_DEVICE_BUILD_DIR}/arm64" SYMROOT="${SYMROOT}" ARCHS=‘arm64‘ VALID_ARCHS=‘arm64‘ $ACTION
#xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}" -configuration "${CONFIGURATION}" -sdk iphoneos BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}"  CONFIGURATION_BUILD_DIR="${IPHONE_DEVICE_BUILD_DIR}/armv7" SYMROOT="${SYMROOT}" ARCHS=‘armv7 armv7s‘ VALID_ARCHS=‘armv7 armv7s‘ $ACTION
# Copy the framework structure to the universal folder (clean it first)
#因为framework的合并,lipo只是合并了最后的二进制可执行文件,所以其它的需要我们自己复制过来
#先移除原来的
rm -rf "${UNIVERSAL_OUTPUTFOLDER}"
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework"
#合并模拟器和真机的架构
lipo -create  "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}""${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"-output"${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}"
open "${UNIVERSAL_OUTPUTFOLDER}"

对于以上的脚本,其中用到了很多的 xcode预定义的变量,这些变量怎么来的呢?你可以在命令行下, 输入

xcodebuild -workspace YohunlUtilsLib.xcworkspace -scheme YohunlUtilsLib -sdk iphonesimulator -configuration Debug -showBuildSettings > xcodebuild_showBuildSettings.txt

来将所有的xcode预定义变量都导入到文本xcodebuild_showBuildSettings.txt 中,然后你就可以选用你需要的啦

当然了,我们一般都应该合并release模式的,而不是debug模式的framework

 

查看.framework的信息：

lipo -info aa.framework/aa

显示：

Architectures in the fat file: aa.framework/aa are: armv7 arm64

说明我们生成的真机framework:aa.framework 包含了两种架构 armv7 arm64

分离架构(以分离armv7为例)

  当前目录建立文件夹,用于存放分离后的架构,和分离出的.o文件

mkdir armV7

分离出armv7架构到文件夹armV7下：

lipo aa.framework/aa -thin armv7 -output ./armv7/aa_armv7

分离armv7架构所有的.o文件

cd armV7
ar -x aa_armv7
