许多答案是不正确的，但得到许多计数。这里我只是编写了一个解决方案，三个视图是水平对齐的，不使用间隔视图，但它只在标签宽度已知的情况下工作，当在故事板中使用。

NSDictionary *views = NSDictionaryOfVariableBindings(_redView, _yellowView, _blueView);

[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"|->=0-[_redView(40)]->=0-[_yellowView(40)]->=0-[_blueView(40)]->=0-|" options:NSLayoutFormatAlignAllTop | NSLayoutFormatAlignAllBottom metrics:nil views:views]];

[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[_redView(60)]" options:0 metrics:nil views:views]];
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:self.view attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:_redView attribute:NSLayoutAttributeCenterY multiplier:1 constant:0]];

[self.view addConstraint:[NSLayoutConstraint constraintWithItem:self.view attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:_yellowView attribute:NSLayoutAttributeCenterX multiplier:1 constant:0]];
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:_redView attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:_yellowView attribute:NSLayoutAttributeLeading multiplier:0.5 constant:0]];
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:_blueView attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:_yellowView attribute:NSLayoutAttributeLeading multiplier:1.5 constant:40]];

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。

Here is a solution that will vertically center any number of subviews, even if they have unique sizes. What you want to do is make a mid-level container, center that in the superview, then put all the subviews in the container and arrange them with respect to one another. But crucially you also need to constrain them to the top and bottom of the container, so the container can be correctly sized and centered in the superview. By figuring the correct height from its subviews, the container can be vertically centered.

在本例中，self是位于所有子视图居中的父视图。

NSArray *subviews = @[ (your subviews in top-to-bottom order) ];

UIView *container = [[UIView alloc] initWithFrame:CGRectZero];
container.translatesAutoresizingMaskIntoConstraints = NO;
for (UIView *subview in subviews) {
    subview.translatesAutoresizingMaskIntoConstraints = NO;
    [container addSubview:subview];
}
[self addSubview:container];

[self addConstraint:[NSLayoutConstraint constraintWithItem:container attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual
                                                    toItem:self attribute:NSLayoutAttributeLeft multiplier:1.0f constant:0.0f]];
[self addConstraint:[NSLayoutConstraint constraintWithItem:container attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual
                                                    toItem:self attribute:NSLayoutAttributeRight multiplier:1.0f constant:0.0f]];
[self addConstraint:[NSLayoutConstraint constraintWithItem:container attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual
                                                    toItem:self attribute:NSLayoutAttributeCenterY multiplier:1.0f constant:0.0f]];

if (0 < subviews.count) {
    UIView *firstSubview = subviews[0];
    [container addConstraint:[NSLayoutConstraint constraintWithItem:firstSubview attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual
                                                             toItem:container attribute:NSLayoutAttributeTop multiplier:1.0f constant:0.0f]];
    UIView *lastSubview = subviews.lastObject;
    [container addConstraint:[NSLayoutConstraint constraintWithItem:lastSubview attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual
                                                             toItem:container attribute:NSLayoutAttributeBottom multiplier:1.0f constant:0.0f]];

    UIView *subviewAbove = nil;
    for (UIView *subview in subviews) {
        [container addConstraint:[NSLayoutConstraint constraintWithItem:subview attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual
                                                                 toItem:container attribute:NSLayoutAttributeCenterX multiplier:1.0f constant:0.0f]];
        if (subviewAbove) {
            [container addConstraint:[NSLayoutConstraint constraintWithItem:subview attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual
                                                                     toItem:subviewAbove attribute:NSLayoutAttributeBottom multiplier:1.0f constant:10.0f]];
        }
        subviewAbove = subview;
    }
}

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

迟到的派对，但我有一个工作的解决方案，创建一个菜单水平间距。在NSLayoutConstraint中使用==可以很容易地做到这一点

const float MENU_HEIGHT = 40;

- (UIView*) createMenuWithLabels: (NSArray *) labels
    // labels is NSArray of NSString
    UIView * backgroundView = [[UIView alloc]init];
    backgroundView.translatesAutoresizingMaskIntoConstraints = false;

    NSMutableDictionary * views = [[NSMutableDictionary alloc] init];
    NSMutableString * format = [[NSMutableString alloc] initWithString: @"H:|"];
    NSString * firstLabelKey;

    for(NSString * str in labels)
    {
        UILabel * label = [[UILabel alloc] init];
        label.translatesAutoresizingMaskIntoConstraints = false;
        label.text = str;
        label.textAlignment = NSTextAlignmentCenter;
        label.textColor = [UIColor whiteColor];
        [backgroundView addSubview: label];
        [label fixHeightToTopBounds: MENU_HEIGHT-2];
        [backgroundView addConstraints: [label fixHeightToTopBounds: MENU_HEIGHT]];
        NSString * key = [self camelCaseFromString: str];
        [views setObject: label forKey: key];
        if(firstLabelKey == nil)
        {
            [format appendString: [NSString stringWithFormat: @"[%@]", key]];
            firstLabelKey = key;
        }
        else
        {
            [format appendString: [NSString stringWithFormat: @"[%@(==%@)]", key, firstLabelKey]];
        }
    }

    [format appendString: @"|"];

    NSArray * constraints = [NSLayoutConstraint constraintsWithVisualFormat: (NSString *) format
                                                                               options: 0
                                                                               metrics: nil
                                                                                 views: (NSDictionary *) views];
    [backgroundView addConstraints: constraints];
    return backgroundView;
}

非常快速的接口构建器解决方案:

对于在一个父视图中均匀间隔的任意数量的视图，简单地给每个水平布局的“对齐中心X到父视图”约束，或垂直布局的“对齐中心Y父视图”，并设置乘数为N:p(注意:有些人有更好的运气p:N -见下文)

在哪里

N =总视图数，和

P =包含空格的视图的位置

第一个位置是1，然后是一个空格，使得下一个位置是3，所以p变成了一个序列[1,3,5,7,9，…]。适用于任何数量的视图。

如果你有3个视图来分隔，它看起来是这样的:

编辑注意:N:p或p:N的选择取决于对齐约束的关系顺序。如果“第一项”是Superview。中心，你可以使用p:N，而如果Superview。中心是“第二项”，你可以用N:p。如果有疑问，可以两种都试一试。: -)
