推荐答案

如果要实现滚动，必须以编程方式添加约束。滚动视图的每一面都必须至少有一个约束。因此，例如，如果您有2个图像，则会有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，您可以设置滚动视图的内容大小。你可以在这里找到Apple的指南这里。

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.
