        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
        }

在Piotr Tomasik的优雅解决方案的基础上:如果你想在按钮标签和图像之间有一点间距，那么包括在你的边缘嵌入如下(复制我的代码在这里完美地为我工作):

    CGFloat spacing          = 3;
    CGFloat insetAmount      = 0.5 * spacing;

    // First set overall size of the button:
    button.contentEdgeInsets = UIEdgeInsetsMake(0, insetAmount, 0, insetAmount);
    [button sizeToFit];

    // Then adjust title and image insets so image is flipped to the right and there is spacing between title and image:
    button.titleEdgeInsets   = UIEdgeInsetsMake(0, -button.imageView.frame.size.width - insetAmount, 0,  button.imageView.frame.size.width  + insetAmount);
    button.imageEdgeInsets   = UIEdgeInsetsMake(0, button.titleLabel.frame.size.width + insetAmount, 0, -button.titleLabel.frame.size.width - insetAmount);

感谢Piotr的解决方案!

一个快速的选项，做什么你想要不玩任何插图:

class RightImageButton: UIButton {

    override func layoutSubviews() {
        super.layoutSubviews()

        if let  textSize = titleLabel?.intrinsicContentSize(),
                imageSize = imageView?.intrinsicContentSize() {
            let wholeWidth = textSize.width + K.textImageGap + imageSize.width
            titleLabel?.frame = CGRect(
                x: round(bounds.width/2 - wholeWidth/2),
                y: 0,
                width: ceil(textSize.width),
                height: bounds.height)
            imageView?.frame = CGRect(
                x: round(bounds.width/2 + wholeWidth/2 - imageSize.width),
                y: RoundRetina(bounds.height/2 - imageSize.height/2),
                width: imageSize.width,
                height: imageSize.height)
        }
    }

    struct K {
        static let textImageGap: CGFloat = 5
    }

}

子类化和覆盖layoutSubviews可能是你最好的方法。

            if (self.currentImage != nil) {

            }
            return titleFrame
        }

当标题发生变化时，只需更新插图即可。你需要在另一侧用等量的、相反的插页来补偿插页。

[thebutton setTitle:title forState:UIControlStateNormal];
thebutton.titleEdgeInsets = UIEdgeInsetsMake(0, -thebutton.imageView.frame.size.width, 0, thebutton.imageView.frame.size.width);
thebutton.imageEdgeInsets = UIEdgeInsetsMake(0, thebutton.titleLabel.frame.size.width, 0, -thebutton.titleLabel.frame.size.width);
