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]; 
// ...

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:

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
}

为macOS Catalyst添加了一些新的视角。由于macOS应用程序支持窗口大小调整，你的UIStackView可能会从一个不可滚动的状态转换为一个可滚动的状态，反之亦然。这里有两件微妙的事情:

UIStackView被设计成适合它所能适应的所有区域。 在过渡期间，UIScrollView将尝试调整其边界大小，以考虑导航栏(或macOS应用程序中的工具栏)下新获得/丢失的区域。

不幸的是，这会造成一个无限循环。我不是非常熟悉UIScrollView和它的adjustdcontentinset，但从我的日志在其layoutSubviews方法，我看到以下行为:

一个人把窗户放大了。 UIScrollView试图缩小它的边界(因为不需要工具栏下面的区域)。 UIStackView。 不知何故UIScrollView不满意，决定恢复到更大的边界。这对我来说感觉很奇怪，因为我从日志中看到的是UIScrollView.bounds.height == UIStackView.bounds.height。 UIStackView。 然后循环到步骤2。

在我看来，有两个步骤可以解决这个问题:

UIStackView一致。top到UIScrollView.topMargin。 设置contentInsetAdjustmentBehavior为。never。

这里我关注的是一个垂直增长的UIStackView的垂直可滚动视图。对于水平对，相应更改代码。

希望它能在未来帮助到任何人。在网上找不到任何人提到这一点，我花了很长时间才弄清楚发生了什么。

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

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()
