编辑情节提要时Xcode接口生成器崩溃

Question

我是Xcode的新手，在使用Interface Builder时遇到IDE崩溃的问题。这是Xcode4.5。

它正常工作了很长时间，足以让我在故事板中添加十几个按钮--但当我试图调整其中任何一个按钮的大小时，它就会崩溃并退出。如果我动一个按钮，它就会崩溃。如果我添加一个像标签这样的新对象，它有时会崩溃，但不总是。

如果我不尝试编辑故事板，项目在模拟器上构建和运行不会有任何问题。

我已经贴了什么看起来像坠毁报告的相关部分在下面。为了节省空间，我从“视图层次结构”部分删除了所有内容，但如果有用的话，我可以添加它。所有的崩溃报告都提到了同一个错误。

有趣的是,当我查看控制台日志时,在每次崩溃之前都会有来自Interface Builder的另一个报告：

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.

根据关于堆栈溢出和其他地方的其他建议，我尝试清理构建，然后删除整个iPhone模拟器目录，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故事板中。这看起来很好。没有撞车。

这是否表明我的另一个项目中有什么东西被破坏了？

提前道谢。

Answer 1

更新：进一步的实验显示了故事板的“使用自动版式”复选框。关闭这个，然后保存文件似乎已经解决了问题。我可以随意编辑，不再崩溃。
