Xcode 7 每次打开时都会崩溃

【问题标题】：Xcode 7 crashes every time when it’s openingXcode 7 每次打开时都会崩溃
【发布时间】：2015-12-29 15:00:00
【问题描述】：

更新 Xcode 7.0.1 后，每次崩溃时，我都无法打开我的工作区。在阅读了所有这些文字后，我明白这是关于集合视图的流布局，以及一些负值。假设我没有机会回到 Xcode 6。有没有人有类似的问题，或者知道如何解决这个问题？

例外：

negative sizes are not supported in the flow layout

关于我的工作空间：

使用

  • 可可足类
  • 故事板
  • 自动布局（某些文件中的纯布局）
  • 未检查大小类

操作系统 OS X 10.11 (macosx10.11)：

这是崩溃日志：

XCODE 版本信息：

版本 = 7.0.1 (7A1001) 插件版本 = 8191 测试版 = 0 操作系统 版本 = 10.10.5 (14F27)

    标签： ios crash storyboard xcode7 flowlayout


    【解决方案1】：

    进入有负值的storyboard或nib修改xml？

    【讨论】：

    • 感谢@Rohan Panchal 的回答。当然有可能，但是给负值在 Xcode 中是绝对有效的，对吧？同样在我的情况下，在布局窗口中没有“负值”（不像例外所说的......）。也许在别的地方。但是再次记住 iOS 6-7 的增量，我们是否使用了负值？我无法打开 Xcode，因为当我尝试打开项目时它崩溃了，但我会用文本编辑器仔细检查。
