can anyone tell me how to get my storyboard back to normal? I'm not sure what I did but all my views seem to be stretched and I can't see the navigation bars at the top of them where I need to make changes to buttons I've put up there.

我不知道原因,但我前段时间遇到了这个问题。
在我的情况下,我有一个 TabBarController 指向几个导航控制器。为了解决这个问题,我刚刚删除了 TabBarController 并将其替换为新的。
如果您没有 TabBarController,我会尝试替换发生拉伸的第一个 NavigationController,它应该修复所有后续视图控制器。
这也发生在我身上。正如 Jeremy 的回应,我有一个 tabBarController,但我通过删除与 tabBar 关联的 viewController 来修复,其中 1 个是导致问题的原因,它是一个导航控制器,我已经更改了标题,所以标题有点大而且那做了控制器扩展。
最简单的解决方案是使用您的版本控制系统回滚。
