@ravron非常出色地给出了这个答案。

在我的例子中，我不仅需要在图像和标题之间添加水平宽度，还需要在按钮的“开头”和“结尾”添加水平空间。

因此，我使用了内部图像和标签的intrinsicContentSize:

接收视图的自然大小，只考虑视图本身的属性。

|                                                                                   |
|[LEADING SPACE] [Image] [SPACE BETWEEN IMAGE AND TITLE] Add To     [TRAILING SPACE]|
|                                                        Favorites      |

let leadingTrailingSpace = 10
let horizontalWidthBetweenImageAndTitle = 4
let insetAmount = horizontalWidthBetweenImageAndTitle / CGFloat(2)
    button.imageEdgeInsets = UIEdgeInsets(top: 0, left: -CGFloat(insetAmount), bottom: 0, right: insetAmount);
    button.titleEdgeInsets = UIEdgeInsets(top: 0, left: CGFloat(insetAmount), bottom: 0, right: -insetAmount);
    button.contentEdgeInsets = UIEdgeInsets(top: 0, left: CGFloat(insetAmount), bottom: 0, right: insetAmount);
    
    let buttonWidth =
        (button.titleLabel?.intrinsicContentSize.width ?? 0) +
        (button.imageView?.intrinsicContentSize.width ?? 0)
        + insetAmount
        + leadingTrailingSpace
    button.widthAnchor.constraint(equalToConstant: buttonWidth).isActive = true

下面是一个如何使用imageEdgeInsets的简单示例 这将创建一个30x30的按钮，可点击区域增大10个像素(50x50)

    var expandHittableAreaAmt : CGFloat = 10
    var buttonWidth : CGFloat = 30
    var button = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    button.frame = CGRectMake(0, 0, buttonWidth+expandHittableAreaAmt, buttonWidth+expandHittableAreaAmt)
    button.imageEdgeInsets = UIEdgeInsetsMake(expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt)
    button.setImage(UIImage(named: "buttonImage"), forState: .Normal)
    button.addTarget(self, action: "didTouchButton:", forControlEvents:.TouchUpInside)

在iOS 15+中，你可以使用UIButton。配置:

var configuration = button.configuration
configuration?.imagePadding = 16
configuration?.titlePadding = 10
            
button.configuration = configuration

在Swift 3中有一种优雅的方式，更好地理解:

override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
    let leftMargin:CGFloat = 40
    let imgWidth:CGFloat = 24
    let imgHeight:CGFloat = 24
    return CGRect(x: leftMargin, y: (contentRect.size.height-imgHeight) * 0.5, width: imgWidth, height: imgHeight)
}

override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
    let leftMargin:CGFloat = 80
    let rightMargin:CGFloat = 80
    return CGRect(x: leftMargin, y: 0, width: contentRect.size.width-leftMargin-rightMargin, height: contentRect.size.height)
}
override func backgroundRect(forBounds bounds: CGRect) -> CGRect {
    let leftMargin:CGFloat = 10
    let rightMargin:CGFloat = 10
    let topMargin:CGFloat = 10
    let bottomMargin:CGFloat = 10
    return CGRect(x: leftMargin, y: topMargin, width: bounds.size.width-leftMargin-rightMargin, height: bounds.size.height-topMargin-bottomMargin)
}
override func contentRect(forBounds bounds: CGRect) -> CGRect {
    let leftMargin:CGFloat = 5
    let rightMargin:CGFloat = 5
    let topMargin:CGFloat = 5
    let bottomMargin:CGFloat = 5
    return CGRect(x: leftMargin, y: topMargin, width: bounds.size.width-leftMargin-rightMargin, height: bounds.size.height-topMargin-bottomMargin)
}

如果你想做一些类似的东西

你需要

1.为按钮设置水平和垂直对齐

Find all required values and set UIImageEdgeInsets CGSize buttonSize = button.frame.size; NSString *buttonTitle = button.titleLabel.text; CGSize titleSize = [buttonTitle sizeWithAttributes:@{ NSFontAttributeName : [UIFont camFontZonaProBoldWithSize:12.f] }]; UIImage *buttonImage = button.imageView.image; CGSize buttonImageSize = buttonImage.size; CGFloat offsetBetweenImageAndText = 10; //vertical space between image and text [button setImageEdgeInsets:UIEdgeInsetsMake((buttonSize.height - (titleSize.height + buttonImageSize.height)) / 2 - offsetBetweenImageAndText, (buttonSize.width - buttonImageSize.width) / 2, 0,0)]; [button setTitleEdgeInsets:UIEdgeInsetsMake((buttonSize.height - (titleSize.height + buttonImageSize.height)) / 2 + buttonImageSize.height + offsetBetweenImageAndText, titleSize.width + [button imageEdgeInsets].left > buttonSize.width ? -buttonImage.size.width + (buttonSize.width - titleSize.width) / 2 : (buttonSize.width - titleSize.width) / 2 - buttonImage.size.width, 0,0)];

这将在按钮上排列标题和图像。

此外，请注意更新这在每个转播

import UIKit

extension UIButton {
    // MARK: - UIButton+Aligment

    func alignContentVerticallyByCenter(offset:CGFloat = 10) {
        let buttonSize = frame.size

        if let titleLabel = titleLabel,
            let imageView = imageView {

            if let buttonTitle = titleLabel.text,
                let image = imageView.image {
                let titleString:NSString = NSString(string: buttonTitle)
                let titleSize = titleString.sizeWithAttributes([
                    NSFontAttributeName : titleLabel.font
                    ])
                let buttonImageSize = image.size

                let topImageOffset = (buttonSize.height - (titleSize.height + buttonImageSize.height + offset)) / 2
                let leftImageOffset = (buttonSize.width - buttonImageSize.width) / 2
                imageEdgeInsets = UIEdgeInsetsMake(topImageOffset,
                                                   leftImageOffset,
                                                   0,0)

                let titleTopOffset = topImageOffset + offset + buttonImageSize.height
                let leftTitleOffset = (buttonSize.width - titleSize.width) / 2 - image.size.width

                titleEdgeInsets = UIEdgeInsetsMake(titleTopOffset,
                                                   leftTitleOffset,
                                                   0,0)
            }
        }
    }
}

接口构建器解决方案

事情正在发生变化，现在在XCode 13.1和iOS 15+的尺寸检查器不影响嵌入，而是在属性检查器下有填充和内容嵌入属性，这带来了预期的效果

为了向后兼容，需要在尺寸检查器下做插入，就像@ravron说的那样。在IB中需要做一些组合:

让我们假设图像和标题之间的距离为8pt 添加标题左插图为8页 这将从右侧剪辑文本，所以需要平衡添加-8pt右插入标题 然后按钮的右插入也需要调整增加右插入8pt 完成了!这个按钮在iOS 14和15中看起来很棒
