另一种方法可能是让顶部和底部标签分别具有相对于视图顶部和底部的约束，并让中间视图分别具有相对于第一个和第三个视图的顶部和底部约束。

请注意，通过将视图拖到另一个视图附近，直到出现引导虚线，您可以对约束进行更多的控制——这些虚线表示将形成的两个对象之间的约束，而不是对象和父视图之间的约束。

在这种情况下，您可能希望将约束更改为“大于或等于”所需的值，而不是“等于”以允许它们调整大小。不确定这是否能达到你的目的。

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

我一直在坐过山车，爱自动布局和讨厌它。喜欢它的关键似乎是接受以下几点:

接口构建器的编辑和“有帮助的”自动创建约束在大多数情况下几乎无用 创建类别来简化常见操作是一种拯救，因为代码是如此重复和冗长。

也就是说，你正在尝试的不是直接的，在接口构建器中很难实现。这在代码中很简单。这段代码，在viewDidLoad，创建和定位三个标签，你需要他们:

// Create three labels, turning off the default constraints applied to views created in code
UILabel *label1 = [UILabel new];
label1.translatesAutoresizingMaskIntoConstraints = NO;
label1.text = @"Label 1";

UILabel *label2 = [UILabel new];
label2.translatesAutoresizingMaskIntoConstraints = NO;
label2.text = @"Label 2";

UILabel *label3 = [UILabel new];
label3.translatesAutoresizingMaskIntoConstraints = NO;
label3.text = @"Label 3";

// Add them all to the view
[self.view addSubview:label1];
[self.view addSubview:label2];
[self.view addSubview:label3];

// Center them all horizontally
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:label1 attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0]];

[self.view addConstraint:[NSLayoutConstraint constraintWithItem:label2 attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0]];

[self.view addConstraint:[NSLayoutConstraint constraintWithItem:label3 attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0]];

// Center the middle one vertically
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:label2 attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeCenterY multiplier:1.0 constant:0]];

// Position the top one half way up
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:label1 attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:label2 attribute:NSLayoutAttributeCenterY multiplier:0.5 constant:0]];

// Position the bottom one half way down
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:label3 attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:label2 attribute:NSLayoutAttributeCenterY multiplier:1.5 constant:0]];

我说过，这段代码通过UIView中的一些类别方法简化了很多，但为了清晰起见，这里我做了很多。

对于感兴趣的人来说，这个类别在这里，它有一个方法，可以沿着特定的轴均匀地间隔一个视图数组。

我想水平对齐5张图片，所以我最终遵循了Mete的反应，但有一点不同。

第一个图像将在容器中水平居中，容器的值为0，乘数为1:5:

第二张图片将在容器中水平居中，容器的值为0，乘数为3:5:

其余的图像也是这样。例如，第五张(也是最后一张)图像将在容器中水平居中，容器值为0，乘数为9:5:

正如梅特所解释的，顺序是1,3,5,7,9，等等。位置遵循相同的逻辑:第一个位置是1，然后是空格，然后是下一个位置3，依此类推。

查看https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/AutoLayoutbyExample/AutoLayoutbyExample.html，上面有关于解决问题的详细描述。

这里还有另一个答案。我在回答一个类似的问题时看到了这个问题的链接。我没有看到任何与我类似的答案。所以我想写在这里。

  class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.whiteColor()
        setupViews()
    }

    var constraints: [NSLayoutConstraint] = []

    func setupViews() {

        let container1 = createButtonContainer(withButtonTitle: "Button 1")
        let container2 = createButtonContainer(withButtonTitle: "Button 2")
        let container3 = createButtonContainer(withButtonTitle: "Button 3")
        let container4 = createButtonContainer(withButtonTitle: "Button 4")

        view.addSubview(container1)
        view.addSubview(container2)
        view.addSubview(container3)
        view.addSubview(container4)

        [

            // left right alignment
            container1.leftAnchor.constraintEqualToAnchor(view.leftAnchor, constant: 20),
            container1.rightAnchor.constraintEqualToAnchor(view.rightAnchor, constant: -20),
            container2.leftAnchor.constraintEqualToAnchor(container1.leftAnchor),
            container2.rightAnchor.constraintEqualToAnchor(container1.rightAnchor),
            container3.leftAnchor.constraintEqualToAnchor(container1.leftAnchor),
            container3.rightAnchor.constraintEqualToAnchor(container1.rightAnchor),
            container4.leftAnchor.constraintEqualToAnchor(container1.leftAnchor),
            container4.rightAnchor.constraintEqualToAnchor(container1.rightAnchor),


            // place containers one after another vertically
            container1.topAnchor.constraintEqualToAnchor(view.topAnchor),
            container2.topAnchor.constraintEqualToAnchor(container1.bottomAnchor),
            container3.topAnchor.constraintEqualToAnchor(container2.bottomAnchor),
            container4.topAnchor.constraintEqualToAnchor(container3.bottomAnchor),
            container4.bottomAnchor.constraintEqualToAnchor(view.bottomAnchor),


            // container height constraints
            container2.heightAnchor.constraintEqualToAnchor(container1.heightAnchor),
            container3.heightAnchor.constraintEqualToAnchor(container1.heightAnchor),
            container4.heightAnchor.constraintEqualToAnchor(container1.heightAnchor)
            ]
            .forEach { $0.active = true }
    }


    func createButtonContainer(withButtonTitle title: String) -> UIView {
        let view = UIView(frame: .zero)
        view.translatesAutoresizingMaskIntoConstraints = false

        let button = UIButton(type: .System)
        button.translatesAutoresizingMaskIntoConstraints = false
        button.setTitle(title, forState: .Normal)
        view.addSubview(button)

        [button.centerYAnchor.constraintEqualToAnchor(view.centerYAnchor),
            button.leftAnchor.constraintEqualToAnchor(view.leftAnchor),
            button.rightAnchor.constraintEqualToAnchor(view.rightAnchor)].forEach { $0.active = true }

        return view
    }
}

同样，这也可以用iOS9 UIStackViews很容易做到。

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.greenColor()
        setupViews()
    }

    var constraints: [NSLayoutConstraint] = []

    func setupViews() {

        let container1 = createButtonContainer(withButtonTitle: "Button 1")
        let container2 = createButtonContainer(withButtonTitle: "Button 2")
        let container3 = createButtonContainer(withButtonTitle: "Button 3")
        let container4 = createButtonContainer(withButtonTitle: "Button 4")

        let stackView = UIStackView(arrangedSubviews: [container1, container2, container3, container4])
        stackView.translatesAutoresizingMaskIntoConstraints = false
        stackView.axis = .Vertical
        stackView.distribution = .FillEqually
        view.addSubview(stackView)

        [stackView.topAnchor.constraintEqualToAnchor(view.topAnchor),
            stackView.bottomAnchor.constraintEqualToAnchor(view.bottomAnchor),
            stackView.leftAnchor.constraintEqualToAnchor(view.leftAnchor, constant: 20),
            stackView.rightAnchor.constraintEqualToAnchor(view.rightAnchor, constant: -20)].forEach { $0.active = true }
    }


    func createButtonContainer(withButtonTitle title: String) -> UIView {
        let button = UIButton(type: .Custom)
        button.translatesAutoresizingMaskIntoConstraints = false
        button.backgroundColor = UIColor.redColor()
        button.setTitleColor(UIColor.whiteColor(), forState: .Normal)
        button.setTitle(title, forState: .Normal)
        let buttonContainer = UIStackView(arrangedSubviews: [button])
        buttonContainer.distribution = .EqualCentering
        buttonContainer.alignment = .Center
        buttonContainer.translatesAutoresizingMaskIntoConstraints = false
        return buttonContainer
    }
}

注意，这与上面的方法完全相同。它添加了四个容器视图，这些视图都是均等填充的，每个堆栈视图都添加了一个视图，并在中间对齐。但是，这个版本的UIStackView减少了一些代码，看起来不错。
