这里提到的解决方案停止工作，一旦我启用自动布局。我不得不提出我自己的想法:

子类UIButton和覆盖layoutSubviews方法:

//
//  MIThemeButtonImageAtRight.m
//  Created by Lukasz Margielewski on 7/9/13.
//

#import "MIThemeButtonImageAtRight.h"

static CGRect CGRectByApplyingUIEdgeInsets(CGRect frame, UIEdgeInsets insets);

@implementation MIThemeButtonImageAtRight

- (void)layoutSubviews
{
    [super layoutSubviews];

    CGRect contentFrame = CGRectByApplyingUIEdgeInsets(self.bounds, self.contentEdgeInsets);

    CGRect frameIcon = self.imageView.frame;
    CGRect frameText = self.titleLabel.frame;

    frameText.origin.x = CGRectGetMinX(contentFrame) + self.titleEdgeInsets.left;
    frameIcon.origin.x = CGRectGetMaxX(contentFrame) - CGRectGetWidth(frameIcon);

    self.imageView.frame = frameIcon;
    self.titleLabel.frame = frameText;
}

@end

static CGRect CGRectByApplyingUIEdgeInsets(CGRect frame, UIEdgeInsets insets){

    CGRect f = frame;

    f.origin.x += insets.left;
    f.size.width -= (insets.left + insets.right);
    f.origin.y += (insets.top);
    f.size.height -= (insets.top + insets.bottom);

    return f;

}

结果:

我把功劳都给了inspirre48。基于他的建议和其他问题，我想出了这个。子类UIButton并重写这些方法。

@implementation UIButtonSubclass

- (CGRect)imageRectForContentRect:(CGRect)contentRect
{
    CGRect frame = [super imageRectForContentRect:contentRect];
    frame.origin.x = CGRectGetMaxX(contentRect) - CGRectGetWidth(frame) -  self.imageEdgeInsets.right + self.imageEdgeInsets.left;
    return frame;
}

- (CGRect)titleRectForContentRect:(CGRect)contentRect
{
    CGRect frame = [super titleRectForContentRect:contentRect];
    frame.origin.x = CGRectGetMinX(frame) - CGRectGetWidth([self imageRectForContentRect:contentRect]);
    return frame;
}

@end

在Xcode 13.3中，我通过以下几个步骤解决了这个问题，并为图像添加了填充。

创建按钮后，按照下面列出的步骤执行:

首先定义图像: let symbol = UIImage(named: "把你的符号的名字放在这里") 然后在你创建按钮的viewDidLoad中，初始化1中上面定义的图像，将图像添加到按钮并设置属性: 按钮。setImage(符号，用于:.normal) 按钮。semanticContentAttribute = .forceRightToLeft button.configuration ?。imagePadding = 2

不要忘记将按钮添加到视图。

扩展的方法

使用扩展设置图像右侧自定义偏移

   extension UIButton {
    func addRightImage(image: UIImage, offset: CGFloat) {
        self.setImage(image, for: .normal)
        self.imageView?.translatesAutoresizingMaskIntoConstraints = false
        self.imageView?.centerYAnchor.constraint(equalTo: self.centerYAnchor, constant: 0.0).isActive = true
        self.imageView?.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -offset).isActive = true
    }
}

这是我在swift 5.2上的工作

let sizeOfTitle: CGFloat = 80
let sizeOfImage: CGFloat = 20
yourButton.titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -sizeOfImage , bottom: 0.0, right: sizeOfImage)
yourButton.imageEdgeInsets = UIEdgeInsets(top: 0.0, left: sizeOfTitle, bottom: 0.0, right: -sizeOfTitle)

如果这需要在UIBarButtonItem中完成，则应该使用额外的视图包装 这是可行的

let view = UIView()
let button = UIButton()
button.setTitle("Skip", for: .normal)
button.setImage(#imageLiteral(resourceName:"forward_button"), for: .normal)
button.semanticContentAttribute = .forceRightToLeft
button.sizeToFit()
view.addSubview(button)
view.frame = button.bounds
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: view)

这行不通

let button = UIButton()
button.setTitle("Skip", for: .normal)
button.setImage(#imageLiteral(resourceName:"forward_button"), for: .normal)
button.semanticContentAttribute = .forceRightToLeft
button.sizeToFit()
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: button)
