Xamarin Studio / VS for Mac Storyboard 未打开

Posted 2023-04-13

【中文标题】Xamarin Studio / VS for Mac Storyboard 未打开

【英文标题】：Xamarin Studio / VS for Mac Storyboard not opening

【发布时间】：2017-12-31 12:32:19

【问题描述】：

我买了一台新的 MacBook Pro 来开发 ios 通用应用程序。在我卖掉我的旧代码之前，我将我的代码推送到了 BitBucket 存储库。

现在我已经安装了 VS for Mac 和 Xamarin Studio 并从 bitbucket 中提取了源代码。一切工作正常（构建、调试等），但在情节提要设计器中进行设计将无法正常工作。

我收到以下异常：

根据异常，我的 xml（故事板）无效，无法解析。不知何故，我能够在我的旧 MacBook（6 个月前）上打开故事板。也可以通过 XCode Interface Builder 打开故事板。

有什么建议可以解决这个问题吗？我真的不想开始重新设计我的应用程序。

谢谢！

【问题讨论】：

我通过 App Store 将 Xcode 升级到 v9，但之后没有打开 Xcode。然后我的故事板上出现了这个错误。然后我打开 Xcode 并不得不接受 T&C 并安装一些东西，之后问题就解决了

【参考方案1】：

问题在于 Xcode 界面构建器添加了一个名为“设备”的附加属性，该属性指定了初始设备设置。使用源代码编辑器打开 .xib 并简单地删除“设备”属性，它应该可以正常工作。

阅读更多 - Bug 58804

【讨论】：

将检查并尽快提供反馈！到目前为止，谢谢！

虽然这对我们之前有所帮助 - 升级 Xcode 后，即使没有设备属性，我也会遇到这个问题

我也面临同样的问题。目前使用 XCode 9.0。我删除了设备属性，但仍然遇到相同的异常

这并没有解决我的问题。阅读我的答案以解决问题

【参考方案2】：

经过很长时间，在没有 Xamarin 帮助的情况下，我找到了问题所在。

我为解决问题而采取的步骤：

将整个错误堆栈复制到编辑器 从底部开始阅读（像往常一样） 找出最后一个异常发生的位置 注释掉xml中对应的元素/属性 重复步骤 2 -> 4 直到不出现错误消息

就我而言，有几个无效元素，例如：

    2017-11-30 23:50:42.8] ERROR: Error in type parser for: UIKit.UIFont
System.NotImplementedException: <font key="NSFont" metaFont="smallSystem" />

和

com.xamarin.MTHosting.3d875c911.stderr: 2017-11-30 23:45:45.638 MonoTouchDesignServerUnified[64451:979709] [2017-11-30 23:45:45.6] ERROR: Error in type parser for: UIKit.UIFont
System.NotImplementedException: <font key="NSFont" metaFont="cellTitle" />

所以我只是用“源代码编辑器”打开了我的故事板并注释掉了这些元素。

最后，我可以再次编辑我的故事板了。

【参考方案3】：

虽然安德烈的建议很好，但在很多情况下仍然无效。 我在 3 年前创建了一个旧项目，将新故事板添加到该项目中会返回此错误。 例如，我遇到了诸如 useTraitCollections 和 colorMatched 之类的错误，无法找到。我手动添加了它们，但仍然返回相同的错误。 我在另一个项目上找到了一个工作的故事板代码，并复制到我不工作的项目中。这首先解决了问题，然后您可以修改此情节提要。
