xcode - 无法打开 Storyboard(com.apple.InterfaceBuilder 错误 -1。)

Question

在几位开发人员在我们的一个应用程序中处理 Storyboard之后，我们现在在尝试在 Xcode Interface Builder 中打开 Storyboard时收到此错误:

The document "MainStoryboard_iPhone.storyboard" could not be opened. The operation couldn’t be completed. (com.apple.InterfaceBuilder error -1.)

Check the console log for additional information.

我们都在运行最新版本的 Xcode (4.6.2 4H1003)，并且在 Interface Builder 中对 Storyboard进行了所有更改。控制台日志中没有显示其他信息。我假设错误是指出现日志和调试语句的同一个控制台日志，它是完全空的。

一位开发人员在尝试在我正在开发的另一个应用程序中打开 Storyboard时收到同样的错误。然而，这个 Storyboard在我电脑上的 Xcode 中打开得很好，所以我们当时从不费心去研究这个错误(这第一次发生在几个月前)。但这一次，我们都得到了同样的错误(我们有 4 个人在自己的电脑上测试过打开它)。

我们使用 GitHub 来管理两个项目的源代码控制，使用几个不同的 Git 客户端。关于导致此错误的原因以及如何修复它的任何想法？

更新:这是尝试打开 Storyboard 后在我的计算机上/var/logs/system.log 的输出:

两个日志输出非常相似。在第 6 行的第二个输出的调用堆栈中还有一行: [IDEEditorContext _openNavigableItem:withContentsOfURL:shouldInstallEditorBlock:] (in IDEKit) .第 11 行(第 10 行)引用了方法 IDEEditorModeViewController而不是 IDEEditorGeniusMode .否则日志输出是相同的。

请注意，我们最初收到此错误的第二个 Storyboard不会有 Git 合并冲突的问题，因为我是唯一在此 Storyboard上工作的开发人员。我从来不需要将提交合并到这个存储库，因为我是它的唯一贡献开发人员。

Answer 1

该项目是否使用任何自定义字体？

我一整天都在处理完全相同的问题(尝试了多台具有多个 XCode 版本的计算机)，并且在我安装了项目中的两种自定义字体后，Storyboards 立即能够打开。

我收到了“无效”异常和数组异常的混合。阵列异常导致一位开发人员收到 similar StackOverflow question他意识到我们有自定义字体。
