ios - 尝试在模拟器上运行时 xcode 崩溃

Question

自从我将我的 xcode 更新到版本 5.1.1 后，我在模拟器/设备上的构建/运行失败并出现了很长的问题报告。

这是错误报告的一小部分:

有人知道如何解决这个错误吗？它与代码有关吗？或者它只是对 xcode 5 的升级？谢谢!

Answer 1

重置模拟器(菜单项 iOS Simulator -> Reset Content and Settings ...)。

转到 XCode 产品菜单，按住 Alt 键并单击 Clean Build Folder。

转到 XCode Organizer Projects 选项卡并删除项目的派生数据。

最后关闭并重启 Xcode 和模拟器。

如果这不起作用，请尝试删除应用程序支持库中的模拟器数据 - 文件夹 ~/Library/Application Support/iPhone Simulator。

XCode 可以通过多种方式使自己进入不一致状态。在大多数情况下，上述过程应该可以解决。
