iOS原生混编Flutter模块打包上传App Store错误

解决日期：2019-7.31

环境

• Flutter: 1.7.8
• 使用VSCode编写Flutter模块
• Flutter模块导入方式参考：Google官方的Add Flutter to existing apps

flutter模块的Flutter.framework多了一个x86_64架构，苹果不予许多余加架构信息，所以要移除掉。

方法一：删除对应Flutter.framework的x86_64架构

• cd 到/path/xxx.framework位置
• lipo -info /path/xxx.framework/xxx 查看框架支持的架构
  • 如：lipo -info Users/pppppp/oooooo/path/xxx.framework/xxx
• 删除Flutter模块x86_64：lipo -remove x86_64 xxx -o xxx

  • 如：lipo -remove x86_64 Flutter -o Flutter

    
    移除x86_64

最后虽然移除了，但当我再次编译或运行或打包的时候，在次出现了类似的问题，看来木有完全解决掉。

方法二，脚本移除，但我不成功

类似，检查和IPA /存档删除不支持的架构[x86_64的，I386]

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

方法三：最简单粗暴，一行代码成功，貌似在flutter官方有

• 在最后run script中，添加"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin

  
  问题解决
  

  之前做flutter与原生混编时候Run Script有了前两行，故添加在最后一行。

兜兜转转问题解决了，之前一直有Google搜索，很多答案都是前两种，英文的相关很多，后面去百度搜索，相信很多人遇到过，国内的一些文章应该也会有，后来发现这最简单的。可能先去flutter相关issue找还更快，解决问题思路很重要，即使你是搜索查找答案。
