你可以创建一个tableView并使isScrollEnabled = false。

对于标签，这至少是可行的:

@“H: | -15 -(第一(第二)= =]-[二(= =第三)](第三(= =))-15 - |

如果第一个和第二个有相同的宽度，第二个和第三个有相同的宽度，第三个和第一个有相同的宽度……你可以做水平(H)和垂直(V)。

Android has a method of chaining views together in its constraint based layout system that I wanted to mimic. Searches brought me here but none of the answers quite worked. I didn't want to use StackViews because they tend to cause me more grief down the line than they save up front. I ended up creating a solution that used UILayoutGuides placed between the views. Controlling their width's allows different types of distributions, chain styles in Android parlance. The function accepts a leading and trailing anchor instead of a parent view. This allows the chain to be placed between two arbitrary views rather than distributed inside of the parent view. It does use UILayoutGuide which is only available in iOS 9+ but that shouldn't be a problem anymore.

public enum LayoutConstraintChainStyle {
    case spread //Evenly distribute between the anchors
    case spreadInside //Pin the first & last views to the sides and then evenly distribute
    case packed //The views have a set space but are centered between the anchors.
}

public extension NSLayoutConstraint {

    static func chainHorizontally(views: [UIView],
                                  leadingAnchor: NSLayoutXAxisAnchor,
                                  trailingAnchor: NSLayoutXAxisAnchor,
                                  spacing: CGFloat = 0.0,
                                  style: LayoutConstraintChainStyle = .spread) -> [NSLayoutConstraint] {
    var constraints = [NSLayoutConstraint]()
    guard views.count > 1 else { return constraints }
    guard let first = views.first, let last = views.last, let superview = first.superview else { return constraints }

    //Setup the chain of views
    var distributionGuides = [UILayoutGuide]()
    var previous = first
    let firstGuide = UILayoutGuide()
    superview.addLayoutGuide(firstGuide)
    distributionGuides.append(firstGuide)
    firstGuide.identifier = "ChainDistribution\(distributionGuides.count)"
    constraints.append(firstGuide.leadingAnchor.constraint(equalTo: leadingAnchor))
    constraints.append(first.leadingAnchor.constraint(equalTo: firstGuide.trailingAnchor, constant: spacing))
    views.dropFirst().forEach { view in
        let g = UILayoutGuide()
        superview.addLayoutGuide(g)
        distributionGuides.append(g)
        g.identifier = "ChainDistribution\(distributionGuides.count)"
        constraints.append(contentsOf: [
            g.leadingAnchor.constraint(equalTo: previous.trailingAnchor),
            view.leadingAnchor.constraint(equalTo: g.trailingAnchor)
        ])
        previous = view
    }
    let lastGuide = UILayoutGuide()
    superview.addLayoutGuide(lastGuide)
    constraints.append(contentsOf: [lastGuide.leadingAnchor.constraint(equalTo: last.trailingAnchor),
                                    lastGuide.trailingAnchor.constraint(equalTo: trailingAnchor)])
    distributionGuides.append(lastGuide)

    //Space the according to the style.
    switch style {
    case .packed:
        if let first = distributionGuides.first, let last = distributionGuides.last {
            constraints.append(first.widthAnchor.constraint(greaterThanOrEqualToConstant: spacing))
            constraints.append(last.widthAnchor.constraint(greaterThanOrEqualToConstant: spacing))
            constraints.append(last.widthAnchor.constraint(equalTo: first.widthAnchor))
            constraints.append(contentsOf:
                distributionGuides.dropFirst().dropLast()
                    .map { $0.widthAnchor.constraint(equalToConstant: spacing) }
                )
        }
    case .spread:
        if let first = distributionGuides.first {
            constraints.append(contentsOf:
                distributionGuides.dropFirst().map { $0.widthAnchor.constraint(equalTo: first.widthAnchor) })
        }
    case .spreadInside:
        if let first = distributionGuides.first, let last = distributionGuides.last {
            constraints.append(first.widthAnchor.constraint(equalToConstant: spacing))
            constraints.append(last.widthAnchor.constraint(equalToConstant: spacing))
            let innerGuides = distributionGuides.dropFirst().dropLast()
            if let key = innerGuides.first {
                constraints.append(contentsOf:
                    innerGuides.dropFirst().map { $0.widthAnchor.constraint(equalTo: key.widthAnchor) }
                )
            }
        }
    }

    return constraints
}

我做了一个函数可能会有帮助。 用法示例:

 [self.view addConstraints: [NSLayoutConstraint fluidConstraintWithItems:NSDictionaryOfVariableBindings(button1, button2, button3)
                                                                asString:@[@"button1", @"button2", @"button3"]
                                                               alignAxis:@"V"
                                                          verticalMargin:100
                                                        horizontalMargin:50
                                                             innerMargin:25]];

会导致垂直分布(不好意思没有10个声望来嵌入图像)。如果你改变坐标轴和一些边距值

alignAxis:@"H"
verticalMargin:120
horizontalMargin:20
innerMargin:10

你会得到水平分布。

我是iOS的新手，但是voilà !

我可以在IB中完全解决这个问题:

使约束使每个子视图的中心Y对齐到父视图的下边缘。 将每个约束的乘数设置为1/2n, 3/2n, 5/2n，…，n-1/2n，其中n是要分布的子视图的数量。

因此，如果您有三个标签，请将每个约束的乘数设置为0.1666667、0.5、0.833333。

我找到了一个完美而简单的方法。自动布局不允许你平等地调整空间大小，但它允许你平等地调整视图大小。简单地在你的字段之间放置一些不可见的视图，并告诉自动布局保持它们相同的大小。它工作得很完美!

但有一件事值得注意;当我在界面设计器中减小尺寸时，有时它会混淆，在原来的地方留下一个标签，如果大小改变了奇数个量，它就会发生冲突。除此之外，它工作得很完美。

编辑:我发现冲突成了一个问题。因此，我删除了其中一个间距约束，并将其替换为两个约束，一个大于或等于，一个小于或等于。两者的大小相同，优先级比其他约束低得多。结果没有进一步的冲突。
