我是
Xcode的新手,并且在使用Interface Builder时遇到IDE崩溃的问题.这是Xcode 4.5.
它工作得足够长,我可以添加十几个按钮到故事板 – 但是当我尝试调整其中任何一个,它崩溃并退出.如果我移动按钮,它会崩溃.如果我添加一个新的对象,如标签,它有时会崩溃,但不总是.
如果我不尝试编辑故事板,则该项目在模拟器上构建并运行,没有任何问题.
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,当我看到控制台日志时,每次崩溃之前,还有另一个Interface Builder的报告：
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,我已经尝试清理该版本,然后删除整个iPhone Simulator目录,并让模拟器重新创建它,但这并没有什么不同.
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.好像没事没有崩溃
这是否表明我的另一个项目有什么损坏？
任何建议将是非常欢迎的.这不是一个重要的项目 – 在这个阶段我正在学习我的方式 – 但是如果有什么事情引起问题,那么在Xcode开始任何认真的工作之前,我想对它进行整理.
提前致谢.
