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)
            }
        }
    }
}

你可以用这个——来避免很多麻烦

myButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;   
myButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;

这将自动对齐你所有的内容到左边(或任何你想要的地方)

斯威夫特3:

myButton.contentHorizontalAlignment = UIControlContentHorizontalAlignment.left;   
myButton.contentVerticalAlignment = UIControlContentVerticalAlignment.center;

我来这个派对有点晚，但我想我有一些有用的东西要补充。

Kekoa的答案很好，但正如RonLugge所提到的，它会使按钮不再尊重sizeToFit，更重要的是，它会导致按钮在固有大小时剪辑其内容。呵!

不过,首先

简单解释一下我是如何相信imageEdgeInsets和titleEdgeInsets工作的:

imageEdgeInsets的文档有以下内容:

使用此属性可调整按钮图像的有效绘图矩形的大小和位置。您可以为这四个嵌入(顶部、左侧、底部、右侧)中的每一个指定不同的值。正值会缩小或插入这条边——使它更靠近按钮的中心。负值会使这条边扩大或开始。

我相信这个文档是在想象这个按钮没有标题，只有一个图像的情况下编写的。用这种方式思考更有意义，并且表现得像UIEdgeInsets通常做的那样。基本上，图像的帧(或标题，带有titleEdgeInsets)对于正插入向内移动，对于负插入向外移动。

好吧，那又怎样?

我快到了!这是你默认设置的，设置一个图像和一个标题(按钮边框是绿色的，只是为了显示它的位置):

当你想要图像和标题之间有空格，而又不造成两者被压缩时，你需要设置四个不同的insets，图像和标题各两个。这是因为你不想改变这些元素帧的大小，而只是改变它们的位置。当你开始以这种方式思考时，Kekoa的优秀类别所需要的改变就变得清晰起来:

@implementation UIButton(ImageTitleCentering)

- (void)centerButtonAndImageWithSpacing:(CGFloat)spacing {
    CGFloat insetAmount = spacing / 2.0;
    self.imageEdgeInsets = UIEdgeInsetsMake(0, -insetAmount, 0, insetAmount);
    self.titleEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, -insetAmount);
}

@end

但是等等，你说，当我这样做的时候，我得到了这个:

噢,是的!我忘了，医生警告过我。他们部分地说:

此属性仅用于布局期间定位图像。按钮不使用此属性来确定intrinsicContentSize和sizeThatFits:。

但有一个属性可以提供帮助，那就是contenttedgeinsets。这方面的医生说:

按钮使用这个属性来确定intrinsicContentSize和sizeThatFits:。

听起来不错。所以让我们再一次调整这个类别:

@implementation UIButton(ImageTitleCentering)

- (void)centerButtonAndImageWithSpacing:(CGFloat)spacing {
    CGFloat insetAmount = spacing / 2.0;
    self.imageEdgeInsets = UIEdgeInsetsMake(0, -insetAmount, 0, insetAmount);
    self.titleEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, -insetAmount);
    self.contentEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, insetAmount);
}

@end

得到什么?

在我看来是赢家。

在Swift中工作，却不想做任何思考?下面是Swift扩展的最终版本:

extension UIButton {

    func centerTextAndImage(spacing: CGFloat) {
        let insetAmount = spacing / 2
        let isRTL = UIView.userInterfaceLayoutDirection(for: semanticContentAttribute) == .rightToLeft
        if isRTL {
           imageEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: -insetAmount)
           titleEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount, bottom: 0, right: insetAmount)
           contentEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount, bottom: 0, right: -insetAmount)
        } else {
           imageEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount, bottom: 0, right: insetAmount)
           titleEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: -insetAmount)
           contentEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: insetAmount)
        }
    }
}

在接口生成器中。选择UIButton -> Attributes Inspector -> Edge=Title并修改边缘插入

在swift 5.3和@ravron的启发下回答:

extension UIButton {
    /// Fits the image and text content with a given spacing
    /// - Parameters:
    ///   - spacing: Spacing between the Image and the text
    ///   - contentXInset: The spacing between the view to the left image and the right text to the view
    func setHorizontalMargins(imageTextSpacing: CGFloat, contentXInset: CGFloat = 0) {
        let imageTextSpacing = imageTextSpacing / 2
        
        contentEdgeInsets = UIEdgeInsets(top: 0, left: (imageTextSpacing + contentXInset), bottom: 0, right: (imageTextSpacing + contentXInset))
        imageEdgeInsets = UIEdgeInsets(top: 0, left: -imageTextSpacing, bottom: 0, right: imageTextSpacing)
        titleEdgeInsets = UIEdgeInsets(top: 0, left: imageTextSpacing, bottom: 0, right: -imageTextSpacing)
    }
}

它增加了一个额外的水平边距，从视图到图像，从标签到视图

Riley Avron回答的一个小补充，以解释地区变化:

extension UIButton {
    func centerTextAndImage(spacing: CGFloat) {
        let insetAmount = spacing / 2
        let writingDirection = UIApplication.sharedApplication().userInterfaceLayoutDirection
        let factor: CGFloat = writingDirection == .LeftToRight ? 1 : -1

        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount*factor, bottom: 0, right: insetAmount*factor)
        self.titleEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount*factor, bottom: 0, right: -insetAmount*factor)
        self.contentEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: insetAmount)
    }
}
