Xcode 4.5故事板崩溃

当我尝试在故事板中编辑UILabels时，Xcode会崩溃。任何想法可能导致这种情况？看起来它与自动布局约束之一有关。这里的错误报告：Xcode 4.5故事板崩溃

我在使用故事板中的元素时遇到了Xcode崩溃的问题，但在Google搜索后找不到答案。我想添加（如果它帮助任何人找到答案）：我只有在Xcode（4.5）的最新更新之后才体会到它，在复制/粘贴故事板中的圆形按钮时以及在调整大小时标签。我正在运行OS X 10.8.2。 – JoeFryer

这里同样的问题。我不知道是什么造成的，但令人难以置信的令人沮丧。同样，每当我尝试添加另一个圆形按钮时也是如此。 – Robert

我有同样的问题......当在“Rounded Rect Buttons”故事板工作它崩溃。有时用一个或两个按钮，有时我可以添加十个按钮，然后崩溃。

编辑：经过一些实验后，我没有选中故事板的“文件检查器”中的“使用Autolayout”，它的工作原理。也许你会试试看。

感谢您的建议，当我每次添加容器视图时，IB都会崩溃。每当我添加一个，嵌入segue就会指向视图控制器场景，看起来像零宽度（在故事板上非常细小的场景）。取消选中“使用Autolayout”后，创建的场景与容器视图大小相同，因为它应该是。之后您可以重新启用Autolayout。 – Stuart

我遇到同样的问题。不幸的是，取消选中“使用Autolayout”并不能解决问题。 –

解决方法是将&从故事板粘贴到.xib。

*对于我来说，当ContainerView被拖到画布上时，它会在IB中使用.xib崩溃。 Xcode版本8.2.1。
