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!

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]; 
// ...

我给你一个正确的解决方案

对于 Xcode 11+

步骤1: 添加一个ScrollView并调整它的大小

步骤2: 为ScrollView添加约束

步骤3: 添加一个StackView到ScrollView，并调整它的大小。

步骤4: 为StackView添加约束(Stask View ->内容布局指南->“领先，顶部，后面，底部”)

步骤4.1: 正确的约束->常量(…->常量= 0)

步骤5: 为StackView添加约束(Stask View -> Frame Layout Guide -> "Equal width ")

步骤6示例: 添加两个带有HeightConstraints和RUN的UIView

希望对大家有用

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:

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
