iphone - 当我单击 XIB 文件时，Xcode 4.2 崩溃

Question

过去一个月我一直在使用 Xcode 4.2，没有出现任何问题。两天前，我回到我的项目，向我的应用程序添加一些导航栏。当我点击 .XIB(任一)时，xcode 崩溃了。

我尝试启动一个新项目，但最终得到了完全相同的结果。我 sudo 完全删除了 xcode 并进行了全新安装。不幸的是，问题仍然存在，我无法升级到最新的 Xcode，因为我唯一可以访问的 mac 是 2006 款 macbook，与 Mountain Lion 不兼容。

下面是 Xcode 启动时出现的错误消息。

这似乎是 cocoa 的问题，但我不知所措。

Answer 1

如果你确实无法升级到 xCode 4.4...

你使用TimeMachine吗？

尝试倒回整个系统...
