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。

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)

对于这个问题，你可以在“label with UIImage view”中创建UIView，并将UIView类设置为UIControl，并创建IBAction为tuch up inside

这里是解决方案的UIButton与中心对齐的内容。 这段代码使图像右对齐，并允许使用imageEdgeInsets和titleEdgeInsets进行宝贵的定位。

用你的自定义类子类化UIButton并添加:

- (CGRect)imageRectForContentRect:(CGRect)contentRect {
    CGRect frame = [super imageRectForContentRect:contentRect];
    CGFloat imageWidth = frame.size.width;
    CGRect titleRect = CGRectZero;
    titleRect.size = [[self titleForState:self.state] sizeWithAttributes:@{NSFontAttributeName: self.titleLabel.font}];
    titleRect.origin.x = (self.frame.size.width - (titleRect.size.width + imageWidth)) / 2.0 + self.titleEdgeInsets.left - self.titleEdgeInsets.right;
    frame.origin.x = titleRect.origin.x + titleRect.size.width - self.imageEdgeInsets.right + self.imageEdgeInsets.left;
    return frame;
}

- (CGRect)titleRectForContentRect:(CGRect)contentRect {
    CGFloat imageWidth = [self imageForState:self.state].size.width;
    CGRect frame = [super titleRectForContentRect:contentRect];
    frame.origin.x = (self.frame.size.width - (frame.size.width + imageWidth)) / 2.0 + self.titleEdgeInsets.left - self.titleEdgeInsets.right;
    return frame;
}

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);
    }
