推荐答案

如果要实现滚动，必须以编程方式添加约束.并且滚动视图的每一侧都必须至少有一个与之相关的约束.因此，例如，如果您有 2 个图像，您将有 3 个水平约束:|-firstImage-secondImage-| 和每个图像的 2 个垂直约束:V:|-fistImage-| 和 V:|-secondImage-|.这样您就可以设置滚动视图的内容大小.您可以在 这里找到 Apple 指南.

You have to add constraints programmatically if you want to achieve scrolling. And each side of your scroll view has to have at lest one constraint tied to it. So for example if you have 2 images you would have 3 horizontal constraints: |-firstImage-secondImage-| and 2 vertical constraints for every image: V:|-fistImage-| and V:|-secondImage-|. This way you can set the content size of your scroll view. You can find the Apple's guide here.
