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
# 对特定的库进行处理
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
