动态库裁剪脚本在XCode14报错

支持模拟器的动态库在上传App Store时，需要裁减掉模拟器的架构。

近期有个项目的打包电脑升级了xcode14，在archive时，Run Script总是报错，原因是lipo -extract 处理的SDK不是一个Fat binary, 同样的脚本在xcode13上是好的。

后来发现是xcode14移除了armv7的原因。项目中的Pod在xcode13上导出的framework是Fat binary（armv7 arm64）,在xcode14上导出的是Single binary（arm64），只需要修改下脚本，增加个判断，避免对Single binary执行lipo -extract。

这里贴上网上看到的xcode14可以用的脚本

strip_invalid_archs() {
    binary="$1"
    echo "current binary ${binary}"
    # Get architectures for current file
    archs="$(lipo -info "$binary" | rev | cut -d ':' -f1 | rev)"
    stripped=""
    for arch in $archs; do
        if ! [[ "${ARCHS}" == *"$arch"* ]]; then
            if [ -f "$binary" ]; then
                # Strip non-valid architectures in-place
                lipo -remove "$arch" -output "$binary" "$binary" || exit 1
                stripped="$stripped $arch"
            fi
        fi
    done
    if [[ "$stripped" ]]; then
        echo "Stripped $binary of architectures:$stripped"
    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)
    if [ ! -n $FRAMEWORK_EXECUTABLE_NAME  ];then
        #如果framework文件不存在info.plist则直接取frmeworl名为二进制文件名
        FRAMEWORK_EXECUTABLE_NAME=$FRAMEWORK
    fi
    FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
    echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"

    strip_invalid_archs "$FRAMEWORK_EXECUTABLE_PATH"
done

xcode14上有问题的脚本（以前网上拷贝的），需要修改下在使用

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"

    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
