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]; 
// ...

正如Eik所说，UIStackView和UIScrollView很好地结合在一起。

关键是UIStackView处理不同内容的可变高度/宽度，然后UIScrollView做它的工作很好地滚动/反弹内容:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    scrollView.contentSize = CGSize(width: stackView.frame.width, height: stackView.frame.height)       
}

苹果的自动布局指南包括了一个关于使用滚动视图的完整部分。一些相关片段:

Pin the content view’s top, bottom, leading, and trailing edges to the scroll view’s corresponding edges. The content view now defines the scroll view’s content area. (Optional) To disable horizontal scrolling, set the content view’s width equal to the scroll view’s width. The content view now fills the scroll view horizontally. (Optional) To disable vertical scrolling, set the content view’s height equal to the scroll view’s height. The content view now fills the scroll view horizontally.

此外:

你的布局必须完全定义内容视图的大小(除了 . ...当内容视图比滚动视图高时，滚动视图允许垂直滚动。当内容视图比滚动视图宽时，滚动视图启用水平滚动。

To summarize, the scroll view's content view (in this case, a stack view) must be pinned to its edges and have its width and/or height otherwise constrained. That means that the contents of the stack view must be constrained (directly or indirectly) in the direction(s) in which scrolling is desired, which might mean adding a height constraint to each view inside a vertically scrolling stack view, for example. The following is an example of how to allow for vertical scrolling of a scroll view containing a stack view:

// Pin the edges of the stack view to the edges of the scroll view that contains it
stackView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
stackView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
stackView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true
stackView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true

// Set the width of the stack view to the width of the scroll view for vertical scrolling
stackView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true

在我的例子中，stackView内的视图数量是可变的，我想将项目居中。例如，在stackView中有一个视图，我希望这个视图位于屏幕中央，如果所有的视图都不适合屏幕，我希望视图是可滚动的。

这是我的视图的层次结构。

所以我为按钮设置了一个固定的宽度，然后，为stackView:

与按钮相同的固定宽度，但优先级为650。 对齐X中心到containerView 尾随>= 0和前导>= 0到containerView 底部和顶部空间到containerView

对于containerView:

拖尾，领先，底部，顶部，等高，等宽(250优先级)到superview 固定的高度

对于scrollView:

尾随，领先，底部，顶部到父视图

scrollView也嵌入到具有前导和后导约束的视图中。

关于我用来解决这个问题的代码:

for index in 0...array.count - 1 {

      if index == 0 {
          firstButton.setTitle(title, for: .normal)
      } else {
          let button = UIButton()
          button.setTitle(title, for: .normal)
          stackView.addArrangedSubview(button)
          stackView.setNeedsLayout()
      }
}
containerView.layoutIfNeeded()
        
stackView.distribution = .fillEqually
stackView.spacing = 10
stackView.alignment = .fill

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
