编辑故事板时,Xcode Interface Builder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Xcode 4.5.

它工作得足够长,我可以在故事板上添加十几个按钮 - 但是当我尝试调整其中任何一个按钮时,它会崩溃并退出.如果我移动按钮,它会崩溃.如果我添加一个像标签这样的新对象,它有时会崩溃,但并非总是如此.

如果我不尝试编辑故事板,项目将在模拟器上构建并运行,没有任何问题.

我粘贴了下面崩溃报告的相关部分.为了节省空间,我已经从"视图层次结构"部分向下删除了所有内容,但如果它有用,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Console日志时,在每次崩溃之前,还有来自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.

这是正确的 - 该目录不存在.我有iPhone模拟器/ 6.0,但没有别的.我以该路径中的用户身份登录.

基于Stack Overflow和其他地方的其他建议,我已经尝试清理构建然后删除整个iPhone模拟器目录并让模拟器重新创建它,但这没有任何区别.

作为一项实验,我刚刚创建了一个新项目并将一些按钮和标签拖入故事板.这看起来很好.没有崩溃.

这是否表明我的其他项目中的某些内容已损坏？

任何建议都会非常受欢迎.这不是一个重要的项目 - 我正在这个阶段学习我的方法 - 但如果出现问题,那么我想在Xcode开始任何认真的工作之前对其进行排序.

提前致谢.

Answer 1

更新:进一步的实验显示故事板的"使用Autolayout"复选框.关闭它然后保存文件似乎已解决问题.我可以随意编辑,不会再崩溃.
