我也想做同样的事情，偶然发现了这个优秀的帖子。如果您希望使用锚API以编程方式完成此操作，则可以采用这种方式。

总之，在UIScrollView中嵌入UIStackView，并设置UIStackView的锚约束来匹配UIScrollView的锚约束:

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

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。

只需将这个添加到viewdidload:

let insets = UIEdgeInsetsMake(20.0, 0.0, 0.0, 0.0)
scrollVIew.contentInset = insets
scrollVIew.scrollIndicatorInsets = insets

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

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

First and foremost design your view, preferably in something like Sketch or get an idea of what do you want as a scrollable content. After this make the view controller free form (choose from attribute inspector) and set height and width as per the intrinsic content size of your view (to be chosen from the size inspector). After this in the view controller put a scroll view and this is a logic, which I have found to be working almost all the times in iOS (it may require going through the documentation of that view class which one can obtain via command + click on that class or via googling) If you are working with two or more views then first start with a view, which has been introduced earlier or is more primitive and then go to the view which has been introduced later or is more modern. So here since scroll view has been introduced first, start with the scroll view first and then go to the stack view. Here put scroll view constraints to zero in all direction vis-a-vis its super view. Put all your views inside this scroll view and then put them in stack view.

当使用堆栈视图时

First start with grounds up(bottoms up approach), ie., if you have labels, text fields and images in your view, then lay out these views first (inside the scroll view) and after that put them in the stack view. After that tweak the property of stack view. If desired view is still not achieved, then use another stack view. If still not achieved then play with compression resistance or content hugging priority. After this add constraints to the stack view. Also think of using an empty UIView as filler view, if all of the above is not giving satisfactory results.

在创建视图之后，在母堆栈视图和滚动视图之间放置一个约束，同时约束子堆栈视图和母堆栈视图。 希望这个时候它能正常工作，否则你可能会从Xcode得到一个警告，给出建议，阅读它所说的并执行这些建议。希望现在你应该有一个工作视图按照你的期望:)。
