Question

突然间，我的XCode 5项目每次打开时都会导致XCode崩溃。 这不是由源控件引起的，因为已禁用。这是堆栈strace。

abort() called

Answer 1

这似乎是由我在我的一个观点中指定的IB约束引起的。以下是我为解决这个问题所做的工作。

打开导致问题的* .storyboard文件
如果您碰巧知道“场景”导致崩溃的原因（例如，如果您正在处理一个项目而且它突然崩溃了您），那么在XML中找到该场景。
查找该场景中的所有<constraints>个部分，并在继续尝试打开XCode的同时逐个删除它们。

一旦找到导致问题的约束，你应该是好的。希望这有助于节省其他人一些时间。

Answer 2

您是否尝试过删除插件？它们位于以下目录中：

~/Library/Application Support/Developer/Shared/Xcode/Plug-ins

如果没有尝试以下内容：

删除衍生数据rm -rf ~/library/Developer/Xcode/DerivedData
删除Xcode并重新安装吗？

Answer 3

我认为您可以通过在添加AutoLayout之前将更改还原到上一个故事板来解决此问题。 Xcode for Autolayout的新警告和提示功能是罪魁祸首。这个问题也应该报告给Apple。
