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!

要在UIButton内右对齐图像，请尝试下面的代码

btn.contentHorizontalAlignment = .right

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);
    }

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

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

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:
