将stackview中的动态元素嵌入到scrollview中的一种简单方法。在XIB中，在UIScrollView中添加一个UIStackView，并添加stackview适合scrollview的约束(top, bottom, lead, trail)，并添加一个约束来匹配它们之间的水平中心。但是将最后一个约束标记为“在构建时移除”。它使XIB高兴，避免错误。

水平滚动示例:

然后:

然后在你的代码中，像这样在你的stackview中添加按钮这样的元素:

array.forEach { text in
     let button = ShadowButton(frame: .zero)
     button.setTitle(text, for: .normal)
     myStackView.addArrangedSubview(button)
     button.heightAnchor.constraint(equalToConstant: 40).isActive = true
     button.widthAnchor.constraint(equalToConstant: 80).isActive = true
}

如果有人在找水平滚动视图

func createHorizontalStackViewsWithScroll() {
    self.view.addSubview(stackScrollView)
    stackScrollView.translatesAutoresizingMaskIntoConstraints = false
    stackScrollView.heightAnchor.constraint(equalToConstant: 85).isActive = true
    stackScrollView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor).isActive = true
    stackScrollView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor).isActive = true
    stackScrollView.bottomAnchor.constraint(equalTo: visualEffectViews.topAnchor).isActive = true
    stackScrollView.addSubview(stackView)
    
    stackView.translatesAutoresizingMaskIntoConstraints = false
    stackView.topAnchor.constraint(equalTo: stackScrollView.topAnchor).isActive = true
    stackView.leadingAnchor.constraint(equalTo: stackScrollView.leadingAnchor).isActive = true
    stackView.trailingAnchor.constraint(equalTo: stackScrollView.trailingAnchor).isActive = true
    stackView.bottomAnchor.constraint(equalTo: stackScrollView.bottomAnchor).isActive = true
    stackView.heightAnchor.constraint(equalTo: stackScrollView.heightAnchor).isActive = true
    
    stackView.distribution = .equalSpacing
    stackView.spacing = 5
    stackView.axis = .horizontal
    stackView.alignment = .fill
    
    for i in 0 ..< images.count {
        let photoView = UIButton.init(frame: CGRect(x: 0, y: 0, width: 85, height: 85))
        // set button image
        photoView.translatesAutoresizingMaskIntoConstraints = false
        photoView.heightAnchor.constraint(equalToConstant: photoView.frame.height).isActive = true
        photoView.widthAnchor.constraint(equalToConstant: photoView.frame.width).isActive = true
        
        stackView.addArrangedSubview(photoView)
    }
    stackView.setNeedsLayout()
}

这里投票最多的答案中的约束条件对我来说是有效的，我已经将在我的故事板中创建的约束条件的图像粘贴在下面。

我确实提到了两个问题，但其他人应该注意:

After adding constraints similar to those in in the accepted answer, I'd get the red autolayout error Need constraints for: X position or width. This was solved by adding a UILabel as a subview of the stack view. I'm adding the subviews programmatically, so I originally had no subviews on the storyboard. To get rid of the autolayout errors, add a subview to the storyboard, then remove it on load before adding your real subviews and constraints. I originally attempted to add UIButtons to the UIStackView. The buttons and views would load, but the scroll view would not scroll. This was solved by adding UILabels to the Stack View instead of buttons. Using the same constraints, this view hierarchy with the UILabels scrolls but the UIButtons does not. I'm confused by this issue, as the UIButtons do seem to have an IntrinsicContentSize (used by the Stack View). If anyone knows why the buttons don't work, I'd love to know why.

下面是我的视图层次结构和约束，供参考:

如果有人正在寻找一个没有代码的解决方案，我创建了一个例子来完成这完全在故事板，使用自动布局。

你可以从github上得到。

基本上，要重新创建这个示例(用于垂直滚动):

创建一个UIScrollView，并设置它的约束。 添加一个UIStackView到UIScrollView 设置约束:前导，后尾，顶部和底部应该等于UIScrollView中的约束 在UIStackView和UIScrollView之间设置一个等宽约束。 在UIStackView上设置轴=垂直，对齐=填充，分布=等间距，间距= 0 添加一些uiview到UIStackView 运行

在第4步中将宽度交换为高度，并在第5步中设置轴=水平，以获得水平的UIStackView。

水平滚动(UIScrollView中的UIStackView)

用于水平滚动。首先，创建一个UIStackView和一个UIScrollView，并按以下方式将它们添加到您的视图中:

let scrollView = UIScrollView()
let stackView = UIStackView()

scrollView.addSubview(stackView)
view.addSubview(scrollView)

记住在UIStackView和UIScrollView上设置translatesAutoresizingMaskIntoConstraints为false:

stackView.translatesAutoresizingMaskIntoConstraints = false
scrollView.translatesAutoresizingMaskIntoConstraints = false

为了让一切正常工作，UIStackView的尾随，领先，顶部和底部锚应该等于UIScrollView锚:

stackView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
stackView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true
stackView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
stackView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true

但是UIStackView的宽度锚点必须等于或大于UIScrollView锚点的宽度:

stackView.widthAnchor.constraint(greaterThanOrEqualTo: scrollView.widthAnchor).isActive = true

现在锚定你的UIScrollView，例如:

scrollView.heightAnchor.constraint(equalToConstant: 80).isActive = true
scrollView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true

scrollView.bottomAnchor.constraint(equalTo:view.safeAreaLayoutGuide.bottomAnchor).isActive = true
scrollView.leadingAnchor.constraint(equalTo:view.leadingAnchor).isActive = true
scrollView.trailingAnchor.constraint(equalTo:view.trailingAnchor).isActive = true 

接下来，我建议尝试以下设置UIStackView对齐和分布:

topicStackView.axis = .horizontal
topicStackView.distribution = .equalCentering
topicStackView.alignment = .center

topicStackView.spacing = 10

最后，你需要使用addArrangedSubview:方法来添加子视图到你的UIStackView。

文本Insets

另一个你可能会发现有用的特性是，因为UIStackView保存在UIScrollView中，你现在可以访问文本insets，使事情看起来更漂亮一点。

let inset:CGFloat = 20
scrollView.contentInset.left = inset
scrollView.contentInset.right = inset

// remember if you're using insets then reduce the width of your stack view to match
stackView.widthAnchor.constraint(greaterThanOrEqualTo: topicScrollView.widthAnchor, constant: -inset*2).isActive = true

例如，垂直堆栈视图/滚动视图(使用EasyPeasy自动布局):

let scrollView = UIScrollView()
self.view.addSubview(scrollView)
scrollView <- [
    Edges(),
    Width().like(self.view)
]

let stackView = UIStackView(arrangedSubviews: yourSubviews)
stackView.axis = .vertical
stackView.distribution = .fill    
stackView.spacing = 10
scrollView.addSubview(stackView)
stackView <- [
    Edges(),
    Width().like(self.view)
]

只要确保每个子视图的高度都已定义!
