NSrangeException导致接口构建器行动怪异

Question

我的“ main.storyboard”文件有问题。我正在使用Xcode 13.3.1。这是接口构建器的图像：

如您所见，视图控制器之一仅显示其子视图的边界。

这是我单击“报告错误”时收到的“ log.txt”文件：

*** -[__NSArrayM objectAtIndexedSubscript:]: index 0 beyond bounds for empty array

我可能错了，但错误似乎与我的收集视图有关。我将视图放入集合视图而不是堆栈视图中，然后出现了此错误。有人可以帮助我了解错误以及如何解决吗？先感谢您！

Answer 1

好吧，我尝试创建一个新的收集视图，并且奏效了！我知道那很乏味，所以请继续回答。谢谢。
