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!

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

在你的场景中放置一个滚动视图，并调整它的大小，使它充满场景。然后，在滚动视图中放置一个堆栈视图，并在堆栈视图中放置添加项按钮。一旦一切就绪，就设置以下约束条件:

Scroll View.Leading = Superview.LeadingMargin
Scroll View.Trailing = Superview.TrailingMargin
Scroll View.Top = Superview.TopMargin
Bottom Layout Guide.Top = Scroll View.Bottom + 20.0
Stack View.Leading = Scroll View.Leading
Stack View.Trailing = Scroll View.Trailing
Stack View.Top = Scroll View.Top
Stack View.Bottom = Scroll View.Bottom
Stack View.Width = Scroll View.Width

代码:堆栈视图。宽度=滚动视图。宽度是关键。

你可以试试ScrollableStackView: https://github.com/gurhub/ScrollableStackView

它是Objective-C和Swift兼容的库。它可以通过CocoaPods获得。

样本代码(Swift)

import ScrollableStackView

var scrollable = ScrollableStackView(frame: view.frame)
view.addSubview(scrollable)

// add your views with 
let rectangle = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 55))
rectangle.backgroundColor = UIColor.blue
scrollable.stackView.addArrangedSubview(rectangle)
// ...

样例代码(Objective-C)

@import ScrollableStackView

ScrollableStackView *scrollable = [[ScrollableStackView alloc] initWithFrame:self.view.frame];
scrollable.stackView.distribution = UIStackViewDistributionFillProportionally;
scrollable.stackView.alignment = UIStackViewAlignmentCenter;
scrollable.stackView.axis = UILayoutConstraintAxisVertical;
[self.view addSubview:scrollable];

UIView *rectangle = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 55)];
[rectangle setBackgroundColor:[UIColor blueColor]];

// add your views with
[scrollable.stackView addArrangedSubview:rectangle]; 
// ...

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.
