【中文标题】iOS Xcode - 编辑情节提要对象导致视图控制器场景复制另一个场景然后 Xcode 崩溃

【英文标题】：iOS Xcode -Editing Storyboard Objects Results In View Controllers Scenes Duplicating Another Scene Then Xcode Crashing

【发布时间】：2018-01-08 11:16:18

【问题描述】：

我正在开发 Sierra 版本 10.12.6 和 Xcode 8.3，我在 Storyboard 中有 3 个场景，它们都通过 push segues 相互连接。

第一个场景有一个 tableView 和一个带有 imageView 和 2 个标签的单元格。

第二个场景有一个 tableView 和一个带有 imageView 和 4 个标签的单元格。

第 3 个场景有一个 tableView，其中一个包含 3 个标签的单元格和一个 collectionView，其中一个包含 imageView 的单元格。

当我尝试对第三个场景进行调整时，第一和第二个场景会自动更新以匹配第三个场景中的完全相同的元素，然后 Xcode 崩溃。

仅当我尝试对第三个场景进行调整时才会出现此问题。

在第三个场景中，我尝试断开所有对象与其视图控制器的连接，然后进行调整，但第一个和第二个场景仍然复制所有内容，Xcode 崩溃并且当它重新打开时所有连接仍然存在（好像我从未断开它们）。

然后我断开了场景之间的转场，但同样的问题发生了——一旦我对第三个场景进行了调整，其他两个场景就会更新以匹配，然后出现崩溃。

在我打开项目后崩溃后一切恢复正常。

第三个​​场景一直在右边，里面是粉红色的：

在我对第 3 个场景进行调整之前：

在我对第 3 个场景进行调整后：

我尝试使用深度清理、常规清理、删除派生数据、完全卸载 Xcode 然后重新安装它来清理项目，但问题仍然存在。

为什么其他 2 个场景会自动更新以匹配第 3 个场景？

以下是崩溃日志：

【参考方案1】：

Xcode 因库/缓存文件夹中的 IBCocoaTouchAutolayoutArbitrationUnit.m 文件而崩溃。根据这个link，你可以删除你的库/缓存文件夹中的文件（不要删除文件夹本身），你应该没问题。那应该可以解决问题。但为了安全起见，您可能应该将此文件移动到另一个位置而不是删除。还可以尝试在 Xcode 9 beta 中打开您的工作区，看看它是否以相同的方式崩溃并显示相同的错误消息。
