ios - 为什么在使用 flutter 模块构建 iOS 原生应用程序时要修复 "Frameworks/Flutter.framework: Permission denied"？

Question

我创建了一个 iOS 单 View 应用程序 (hostapp) 并将其转换为 Pod 工作区。运行良好。 然后创建flutter模块(clientapp)，提供给iOS团队。运行良好，独立。 关闭了 hostapp 和 clientapp 的 Bitcode，因为它导致了其他问题。 现在通过podfile将clientapp添加到hostapp，内部代码没有更改。在 hostapp 中安装 pod 之后，我尝试构建它。然后它抛出/Users/iVoIP/Library/Developer/Xcode/DerivedData/hostapp-czxdwjjefjvrnhhdvbmaqeczngbh/Build/Products/Debug-iphonesimulator/hostapp.app/Frameworks/Flutter.framework:权限被拒绝

• hostapp 和 clientapp 都是默认的 iOS 和 flutter 应用程序。没有任何变化。
• 我遵循了这个官方指南 https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps .
• 曾尝试搜索类似问题，但没有成功。
• 在 Xcode 10 和 11 上测试
• 尝试过旧版本
• 尝试过 Xcode 11、10、9.3 兼容等
• 将 flutter chmod 更改为 777
• 已将 /Users/iVoIP/Library/Developer/Xcode/DerivedData/hostapp-czxdwjjefjvrnhhdvbmaqeczngbh/Build/Products/Debug-iphonesimulator/hostapp.app/Frameworks/ chmod 更改为 777

Answer 1

在 Flutter 文件夹中的此路径中找到 xcode_backend.sh 文件 ‎flutter/packages/flutter_tools/bin 并在第 140 行将其更改为

    RunCommand find "${derived_dir}/engine/Flutter.framework" -type f -iname '.h' -exec chmod a-w "{}" \;

这样就可以了!!
