1.查看静态库支持的CPU架构

lipo -info libname.a(或者libname.framework/libname)

2. 合并静态库

lipo -create 静态库存放路径1 静态库存放路径2 -output 整合后存放的路径

lipo -create libname-armv7.a libname-armv7s.a libname-i386.a -output libname.a
或者
lipo -create arm7/util.framework/util i386/util.framework/util -output util.framework

3. 静态库拆分

lipo 静态库源文件路径 -thin CPU架构名称 -output 拆分后文件存放路径
架构名为armv7/armv7s/arm64等，与lipo -info 输出的架构名一致
lipo libname.a -thin armv7 -output libname-armv7.a

4.移除

使用lipo -info 可以查看包含的架构
lipo -info AipBase.framework/AipBase

Architectures in the fat file: AipBase are: i386 x86_64 armv7 armv7s arm64

移除x86_64, i386

lipo -remove x86_64 AipBase.framework/AipBase -o AipBase.framework/AipBase
lipo -remove i386 AipBase.framework/AipBase -o AipBase.framework/AipBase
lipo -remove x86_64 AipOcrSdk.framework/AipOcrSdk -o AipOcrSdk.framework/AipOcrSdk
lipo -remove i386 AipOcrSdk.framework/AipOcrSdk -o AipOcrSdk.framework/AipOcrSdk

再次查看

lipo -info AipBase.framework/AipBase # Architectures in the fat file: AipBase are: armv7 armv7s arm64

5.扩展：

发布时，移除特定framework的架构

if [ $CONFIGURATION == Debug ]; then
    echo "调试的时候不做处理"
    exit
fi

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"

# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"


if [ $FRAMEWORK_EXECUTABLE_NAME != XXXXXX ]; then
    #不用处理的库  
    continue
fi

EXTRACTED_ARCHS=()

for ARCH in $ARCHS
do
echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"

lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")


done

echo "Merging extracted architectures: ${ARCHS}"
lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
rm "${EXTRACTED_ARCHS[@]}"

echo "Replacing original executable with thinned version"
rm "$FRAMEWORK_EXECUTABLE_PATH"
mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"

done
