我的项目有问题。我在 Xcode 上构建（在 Visual Studio 代码上开发）时遇到了一堆错误。

直到今天早上，这一切都出乎意料地发生了。我之前遇到过问题：

warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.5.99

我认为它已经解决了：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
    end
  end
end

在 PodFile 中。

然后我仍然收到这个错误，我正在咨询这个错误，所以我尝试将我的 Flutter 从 2.2.0 更新到 2.5.0，并从以下位置更新了我的依赖项：

environment:
  sdk: ">=2.7.0 <3.0.0"

显然，更新我的代码以反映更改，关于如何将其恢复到 iOS 模拟器并恢复正常工作的任何想法？

【问题讨论】：

标签： ios xcode flutter

【解决方案1】：

如果有人遇到此问题，我会进行修复，首先我遇到了 2 个问题：

由于 Xcode 12 中对 iOS 8 的支持下降，我的项目的 Pod 不再工作（Link 中的更多信息）。
为了让它工作，我从 Flutter 2.2.0 更新到 2.5.0，这基本上做了很多改变，并从依赖项所依赖的一些方法中移除了支持。

为了解决这个问题，我做了两件事：

从问题 2 开始，我刚刚使用命令 flutter downgrade 2.2.0 对我的 Flutter 进行了降级，这有助于我回到原来的问题而无需面对去掉那些依赖的方法。

至于第 1 期的事情：

首先将其添加到 PodFile 中：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

其次，为了修复 Pod，我做了以下步骤：

删除 pubspec.lock 文件。

在主项目的终端中

Flutter 清洁了吗。

在终端中转到 iOS 文件夹：

删除 Podfile.lock
删除 Pods 文件夹。
至关重要：复制（无论何时作为备份）PodFile 的内容，包括最后添加的部分。
删除 Podfile。
在 iOS 文件夹的终端中执行 pod init。（这将生成包含基本信息的 Podfile）。
在 iOS 文件夹的终端中进行 pod 安装。（这将生成包含基本信息的 Podfile.lock 和 Pods 文件夹）。

导航到终端中的主项目文件夹 (cd ..) 或使用 pubspec.yaml 文件中的 Pub get 图标。

做一个颤抖的酒吧得到

在终端中转到 iOS 文件夹：

复制第5步备份的存储信息，粘贴到PodFile中。
进行 pod 安装。

导航到终端中的主项目文件夹 (cd ..)

最后，做一个颤动的运行。

这就是我设法解决它的方法。

亲切的问候
