【问题描述】：

在我将 XCode 更新到版本 9 后，当我想在 IOS 11 模拟器中启动应用程序时，我总是会得到一大堆几乎相同的错误。到目前为止，我还没有测试过早期的 ios 版本，但 ios 10 在 XCode 更新之前运行良好。

Launching lib/main.dart on iPhone X in debug mode...
Running Xcode build...

由“flutter create app”生成的标准应用程序运行，但会显示大问题列表。但是，如果我运行我的其他应用程序，它会因这些错误而崩溃。这是一个已知问题吗？有解决办法吗？

【问题讨论】：

  • 我也遇到了类似的错误，即使我尝试运行他们的股票应用程序也是如此。你能在 iOS 11 模拟器中运行 Safari、照片应用吗？它在所有 iOS 11 模拟器设备上不断崩溃。如果我运行 iOS 9.2 就可以了。模拟器虽然。我的问题在这里：stackoverflow.com/questions/46430608/… 你找到解决办法了吗？
  • 我在 IOS 11 模拟器上遇到了同样的错误，(com.apple.WebKit.WebContent): Unknown key for Boolean: EnablePressuredExit，它适用于较低的 IOS 版本，有什么解决方案吗？会不会是 IOS 11 的错误？

【解决方案1】：

对于所有也面临这个问题的人，我的解决方案是：

我做了这些步骤：

按照 Xcode 签名流程配置您的项目：通过在 Flutter 项目目录的终端窗口中运行 open ios/Runner.xcworkspace，打开项目中的默认 Xcode 工作区。在 Xcode 中，选择左侧导航面板中的 Runner 项目。在 Runner 目标设置页面中，确保在 General > Signing > Team 下选择了您的 Development Team。当您选择一个团队时，Xcode 会创建并下载开发证书，使用您的帐户注册您的设备，并创建和下载配置文件（如果需要）。

通过这些步骤，我解决了我在问题中提到的问题，但又出现了另一个问题。

编辑： 在我卸载了flutter并再次克隆了repo之后，我解决了所有这些问题，但是这次master分支不是flutter页面上的入门教程中提到的alpha。

来自颤振页面： git clone -b alpha https://github.com/flutter/flutter.git

修复： git clone -b masterhttps://github.com/flutter/flutter.git

【讨论】：

  • 我正在使用Xamarin，但我认为您的解决方案不适合我。在我升级到 IOS 11 之前它运行良好，不过感谢分享您的解决方案
  • 他们“布尔的未知键”问题消失了，应用程序不再崩溃，但现在我面临无法热重载的问题。但是，如果您说您在使用 Xamarian 时遇到了同样的问题，那么 Apple 在模拟器中进行了一些更改
  • 我现在的问题是终端说我：“（com.apple.videosubscriptionsd）：服务只运行了0秒。将重生推迟10秒。”
