查看CPU结构
查看.a的CPU架构
lipo -info xx.a
查看.framework的CPU架构
1、cd到xx.framework的目录下面
2、lipo -info xx
指令集对应的机型
2018 A12芯片arm64e ： iPhone XS、 iPhone XS Max、 iPhoneXR
2017 A11芯片arm64： iPhone 8, iPhone 8 Plus, and iPhone X
2016 A10芯片arm64：iPhone 7 , 7 Plus, iPad (2018)

armv7：iPhone4｜iPhone4S｜iPad｜iPad2｜iPad3(The New iPad)｜iPad mini｜iPod Touch 3G｜iPod Touch4
模拟器32位 i386架构，
模拟器64位 x86_64架构，
真机32位 armv7 armv7s架构，
真机64位处理器需要arm64 arm64e架构。
.a库文件
编写自己的.a库的时候一般是需要支持（这样真机和模拟器都能使用）
armv7 arm64 i386 x86_64
如果全一点的话也可以包括armv7s、arm64e
armv7 armv7s arm64 arm64e i386 x86_64
每增加一种架构库的大小就会多一倍。
查看Architectures
81CC564AE6BCA0898E7E18DB3C02E6E9.png
只会包含2种架构：armv7 arm64
如果真机需要4种都有的话需要手动填写，在Architectures中加入armv7、armv7s、arm64、arm64e ,注意这种模式下模拟器编译不了的（模拟器需要使用Standard architectures）。

合并模拟和真机的.a文件
- 手动合并
lipo -create "模拟器xx.a" "真机xx.a" -output "xx.a"
lipo -create "xx.a" "xx.a" -output "xx.a"
-
脚本合并
在.a库的工程中添加一个Aggegate目标文件
4D6F1318-EE0F-49A2-8248-004E020EA220.png
在build Phases 添加Run Script项
然后加入脚本
if [ "${ACTION}" = "build" ]
then
#要build的target名
target_Name=${PROJECT_NAME}
echo "target_Name=${target_Name}"
#build之后的文件夹路径
build_DIR=${SRCROOT}/build
echo "build_DIR=${build_DIR}"
#真机build生成的头文件的文件夹路径
DEVICE_DIR_INCLUDE=${build_DIR}/Release-iphoneos/include/${PROJECT_NAME}
echo "DEVICE_DIR_INCLUDE=${DEVICE_DIR_INCLUDE}"
#真机build生成的.a文件路径
DEVICE_DIR_A=${build_DIR}/Release-iphoneos/lib${PROJECT_NAME}.a
echo "DEVICE_DIR_A=${DEVICE_DIR_A}"
#模拟器build生成的.a文件路径
SIMULATOR_DIR_A=${build_DIR}/Release-iphonesimulator/lib${PROJECT_NAME}.a
echo "SIMULATOR_DIR_A=${SIMULATOR_DIR_A}"
#目标文件夹路径
INSTALL_DIR=${SRCROOT}/Products/${PROJECT_NAME}
echo "INSTALL_DIR=${INSTALL_DIR}"
#目标头文件文件夹路径
INSTALL_DIR_Headers=${SRCROOT}/Products/${PROJECT_NAME}/Headers
echo "INSTALL_DIR_Headers=${INSTALL_DIR_Headers}"
#目标.a路径
INSTALL_DIR_A=${SRCROOT}/Products/${PROJECT_NAME}/lib${PROJECT_NAME}.a
echo "INSTALL_DIR_A=${INSTALL_DIR_A}"
#判断build文件夹是否存在，存在则删除
if [ -d "${build_DIR}" ]
then
rm -rf "${build_DIR}"
fi
#判断目标文件夹是否存在，存在则删除该文件夹
if [ -d "${INSTALL_DIR}" ]
then
rm -rf "${INSTALL_DIR}"
fi
#创建目标文件夹
mkdir -p "${INSTALL_DIR}"
#build之前clean一下
xcodebuild -target ${target_Name} clean
#模拟器build
xcodebuild -target ${target_Name} -configuration Release -sdk iphonesimulator
#真机build
xcodebuild -target ${target_Name} -configuration Release -sdk iphoneos
#复制头文件到目标文件夹
cp -R "${DEVICE_DIR_INCLUDE}" "${INSTALL_DIR_Headers}"
#合成模拟器和真机.a包
lipo -create "${DEVICE_DIR_A}" "${SIMULATOR_DIR_A}" -output "${INSTALL_DIR_A}"
#打开目标文件夹
open "${INSTALL_DIR}"
fi
使用默认设置会生成支持4中架构的.a静态库文件（armv7 arm64 i386 x86_64）
具体怎么使用Aggegate可以查看
地址
.framework库
如同.a库一样使用脚本生成支持4种架构的库
脚本如下
# Sets the target folders and the final framework product.
FRAMEWORK_NAME=${PROJECT_NAME}
FRAMEWORK_CONFIG=Release
# Install dir will be the final output to the framework.
# The following line create it in the root folder of the current project.
INSTALL_DIR=${PROJECT_DIR}/Products/${FRAMEWORK_NAME}.framework
# Working dir will be deleted after the framework creation.
WORK_DIR=build
DEVICE_DIR=${WORK_DIR}/${FRAMEWORK_CONFIG}-iphoneos/${FRAMEWORK_NAME}.framework
SIMULATOR_DIR=${WORK_DIR}/${FRAMEWORK_CONFIG}-iphonesimulator/${FRAMEWORK_NAME}.framework
xcodebuild -configuration "${FRAMEWORK_CONFIG}" -target "${FRAMEWORK_NAME}" -sdk iphoneos
echo "Build simulator"
xcodebuild -configuration "${FRAMEWORK_CONFIG}" -target "${FRAMEWORK_NAME}" -sdk iphonesimulator
# Creates install directory if it not exits.
if [ ! -d "${INSTALL_DIR}" ]
then
mkdir -p "${INSTALL_DIR}"
fi
# Creates headers directory if it not exits.
if [ ! -d "${INSTALL_DIR}/Headers" ]
then
mkdir -p "${INSTALL_DIR}/Headers"
fi
# Remove all files in the headers diectory.
for file in `ls "${INSTALL_DIR}/Headers"`
do
rm "${INSTALL_DIR}/Headers/${file}"
done
# Remove binary library file.
rm -f ${INSTALL_DIR}/${FRAMEWORK_NAME}
# Copies the headers files to the final product folder.
if [ -d "${DEVICE_DIR}/Headers" ]
then
for file in `ls "${DEVICE_DIR}/Headers"`
do
cp "${DEVICE_DIR}/Headers/${file}" "${INSTALL_DIR}/Headers/${file}"
done
fi
# copy nibs to bundle,then copy bundle to final folder
BUNDLE_DIR=${DEVICE_DIR}/${FRAMEWORK_NAME}.bundle
if [ -d "${BUNDLE_DIR}" ];then
if ls ${DEVICE_DIR}/*.nib >/dev/null 2>&1;then
rm -rf ${BUNDLE_DIR}/*.nib
cp -rf ${DEVICE_DIR}/*.nib ${BUNDLE_DIR}
fi
rm -rf "${INSTALL_DIR}/${FRAMEWORK_NAME}.bundle"
cp -R "${BUNDLE_DIR}" "${INSTALL_DIR}/${FRAMEWORK_NAME}.bundle"
fi
echo "Merge with simulator"
# Uses the Lipo Tool to merge both binary files (i386 + armv6/armv7) into one Universal final product.
lipo -create "${DEVICE_DIR}/${FRAMEWORK_NAME}" "${SIMULATOR_DIR}/${FRAMEWORK_NAME}" -output "${INSTALL_DIR}/${FRAMEWORK_NAME}"
rm -r "${WORK_DIR}"
