如何以编程方式使用 UIScrollView 使 UIStackView 滚动? [英] How to make UIStackView scroll with UIScrollView programmatically?

问题描述

我见过几种使 UIStackView 与 UIScrollView 一起滚动的解决方案，但它们都依赖于 Autolayout 和 IB.

I have seen several solutions to make UIStackView scroll with UIScrollView but they all rely Autolayout and IB.

有没有办法以编程方式做到这一点?

Is there a way to do it programmatically?

我见过这个例子:https://gist.github.com/twostraws/a02d4cc09fc7bc16859c

但它使用可视化格式语言，而我使用的是布局锚点 API.

But it uses Visual Format Language and I am using the Layout Anchor API.

布局锚点 API:

view.leadingAnchor.constraintEqualToAnchor(otherview.topAnchor).active = true

推荐答案

我本来想做同样的事情，但偶然发现了这个 优秀的帖子. 总而言之，将您的 UIStackView 嵌入到您的 UIScrollView 中，然后通过设置UIStackView 的锚点约束以匹配 UIScrollView 的锚点约束:

I was looking to do the same thing and stumbled upon this excellent post. To summarize, embed your UIStackView in your UIScrollView, and continue in the direction you were thinking by setting the anchor constraints of the UIStackView to match those of the UIScrollView:

stackView.leadingAnchor.constraintEqualToAnchor(scrollView.leadingAnchor).active = true
stackView.trailingAnchor.constraintEqualToAnchor(scrollView.trailingAnchor).active = true
stackView.bottomAnchor.constraintEqualToAnchor(scrollView.bottomAnchor).active = true
stackView.topAnchor.constraintEqualToAnchor(scrollView.topAnchor).active = true
stackView.widthAnchor.constraintEqualToAnchor(scrollView.widthAnchor).active = true
