当我编辑 Storyboard 时，Xcode Interface Builder 崩溃

Question

我是 Xcode 新手，在使用 Interface Builder 时遇到 IDE 崩溃的问题。这是 Xcode 4.5。

它正常工作了足够长的时间，足以让我在 Storyboard中添加十几个按钮 - 但当我尝试调整其中任何一个按钮的大小时，它崩溃并退出。如果我移动按钮，它就会崩溃。如果我添加一个新对象(例如标签)，它有时会崩溃，但并非总是如此。

如果我不尝试编辑 Storyboard ，该项目将在模拟器上构建并运行，不会出现任何问题。

我已经粘贴了下面的崩溃报告的相关部分。为了节省空间，我删除了“ View 层次结构”部分向下的所有内容，但如果有用的话我可以添加它。所有崩溃报告都引用相同的错误。

有趣的是，当我查看控制台日志时，在每次崩溃之前，Interface Builder 都会显示另一份报告:

25/09/2012 10:46:35.661 Interface Builder Cocoa Touch Tool: CFPreferences:
user home directory at file://localhost/Users/me/Library/Application Support/
iPhone Simulator/User/ is unavailable. User domains will be volatile.

这是正确的——该目录不存在。我有 iPhone Simulator/6.0，但没有其他。我以该路径中的用户身份登录。

根据 Stack Overflow 和其他地方的其他建议，我尝试清理构建，然后删除整个 iPhone Simulator 目录并让模拟器重新创建它，但这没有什么区别。

作为一个实验，我刚刚创建了一个新项目并将一些按钮和标签拖到 Storyboard中。看起来不错。没有崩溃。

这是否表明我的其他项目中的某些内容已损坏？

非常欢迎任何建议。这不是一个重要的项目——我在这个阶段正在学习我的方法——但是如果有什么东西导致了问题，那么我想在开始在 Xcode 中开始任何认真的工作之前解决它。

提前致谢。

Answer 1

更新:进一步的实验显示 Storyboard的“使用自动布局”复选框。关闭此功能然后保存文件似乎已经解决了问题。我可以随意编辑，不会再出现崩溃。
