Question

我搞砸了iOS的Xcode。有人要求至少在iOS 10.0上部署相机。我有8.0，但是我按了黄色产量的固定键，然后它更改了代码，这给了我所有这些错误。

我已尝试将备份的Xcode复制和粘贴到意大利面，但无法正常工作。 Pods / Development Pods / camera / open311_s / ios / .symlinks / camera / iOS / classes / Cameraplugin.m我错过了Xcode中的此类。

Xcode的输出： ↳

我可以正常运行该应用程序，但现在无法运行。如何修复Flutter应用程序的Xcode。

Answer 1

解决方案：

我弄乱了flutter使用它的依赖关系提供的相机插件类。您可以在pubspec.yaml中找到它。我已经删除了对相机的依赖，并且该应用能够运行。那应该解决问题。从flutter插件中复制cameraPlugin.m并删除混乱的代码，然后放入新代码。

https://github.com/flutter/plugins/blob/master/packages/camera/ios/Classes/CameraPlugin.m#L25

当我错过了Flutter应用程序之后，有什么方法可以回到我的旧Xcode吗？
