我只是想添加，你可以添加IB_DESIGNABLE之前，你的按钮@interface和设置你的按钮类在storyborad。然后你就可以在界面构建阶段实时观看它的布局，而无需启动应用程序

扩展UiButton并放入这些线条

    if let imageWidth = self.imageView?.frame.width {
        self.titleEdgeInsets = UIEdgeInsetsMake(0, -imageWidth, 0, imageWidth);
    }

    if let titleWidth = self.titleLabel?.frame.width {
        let spacing = titleWidth + 20
        self.imageEdgeInsets = UIEdgeInsetsMake(0, spacing, 0, -spacing);
    }

Xcode 11.4 Swift 5.2

对于任何试图镜像后退按钮样式的人，像这样的雪佛龙:

import UIKit

class NextBarButton: UIBarButtonItem {

    convenience init(target: Any, selector: Selector) {

        // Create UIButton
        let button = UIButton(frame: .zero)

        // Set Title
        button.setTitle("Next", for: .normal)
        button.setTitleColor(.systemBlue, for: .normal)
        button.titleLabel?.font = UIFont.systemFont(ofSize: 17)

        // Configure Symbol
        let config = UIImage.SymbolConfiguration(pointSize: 19.0, weight: .semibold, scale: .large)
        let image = UIImage(systemName: "chevron.right", withConfiguration: config)
        button.setImage(image, for: .normal)

        // Add Target
        button.addTarget(target, action: selector, for: .touchUpInside)

        // Put the Image on the right hand side of the button
        // Credit to liau-jian-jie for this part
        button.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
        button.titleLabel?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
        button.imageView?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)

        // Customise spacing to match system Back button
        button.imageEdgeInsets = UIEdgeInsets(top: 0.0, left: -18.0, bottom: 0.0, right: 0.0)
        button.titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -12.0, bottom: 0.0, right: 0.0)

        self.init(customView: button)
    }
}

实现:

override func viewDidLoad() {
    super.viewDidLoad()
    let nextButton = NextBarButton(target: self, selector: #selector(nextTapped))
    navigationItem.rightBarButtonItem = nextButton
}

@objc func nextTapped() {
    // your code
}

用于编程UI设计

 lazy var buttonFilter : ButtonRightImageLeftTitle = {
    var button = ButtonRightImageLeftTitle()
    button.setTitle("Playfir", for: UIControl.State.normal)
    button.setImage(UIImage(named: "filter"), for: UIControl.State.normal)
    button.backgroundColor = UIColor.red
    button.contentHorizontalAlignment = .left
    button.titleLabel?.font = UIFont.systemFont(ofSize: 16)
    return button
}()

边缘插入值应用于矩形以收缩或展开 用矩形表示的面积。通常，使用边缘嵌入 在视图布局期间修改视图的框架。积极的价值观 将被插入(或缩小)指定数量的帧。负 值使帧由指定的对象开始(或展开) 量。

class ButtonRightImageLeftTitle: UIButton {

    override func layoutSubviews() {
        super.layoutSubviews()

        guard imageView != nil else { return }

        imageEdgeInsets = UIEdgeInsets(top: 5, left: (bounds.width - 35), bottom: 5, right: 5)
        titleEdgeInsets = UIEdgeInsets(top: 0, left: -((imageView?.bounds.width)! + 10), bottom: 0, right: 0 )

    }
}

用于StoryBoard UI设计

更新:Swift 3

class ButtonIconRight: UIButton {
    override func imageRect(forContentRect contentRect:CGRect) -> CGRect {
        var imageFrame = super.imageRect(forContentRect: contentRect)
        imageFrame.origin.x = super.titleRect(forContentRect: contentRect).maxX - imageFrame.width
        return imageFrame
    }

    override func titleRect(forContentRect contentRect:CGRect) -> CGRect {
        var titleFrame = super.titleRect(forContentRect: contentRect)
        if (self.currentImage != nil) {
            titleFrame.origin.x = super.imageRect(forContentRect: contentRect).minX
        }
        return titleFrame
    }
}

Swift 2的原始答案:

一个解决方案，处理所有水平对齐，与一个Swift实现示例。如果需要，只需翻译成Objective-C即可。

class ButtonIconRight: UIButton {
    override func imageRectForContentRect(contentRect:CGRect) -> CGRect {
        var imageFrame = super.imageRectForContentRect(contentRect)
        imageFrame.origin.x = CGRectGetMaxX(super.titleRectForContentRect(contentRect)) - CGRectGetWidth(imageFrame)
        return imageFrame
    }

    override func titleRectForContentRect(contentRect:CGRect) -> CGRect {
        var titleFrame = super.titleRectForContentRect(contentRect)
        if (self.currentImage != nil) {
            titleFrame.origin.x = CGRectGetMinX(super.imageRectForContentRect(contentRect))
        }
        return titleFrame
    }
}

同样值得注意的是，它处理相当好图像和标题插入。

灵感来自jasongregori的回答;)

在界面构建器中，您可以为UIButton配置选项边缘插入，分别为三个部分:内容，图像，标题
