1.NSMutableAttributedString如何显示图片

    NSMutableAttributedString *vipStr = [[NSMutableAttributedString alloc]initWithString:@"点击解锁【超级方法】"];
    UIImage *vipImage = [UIImage imageNamed:@"WordDetailNor解锁"];
    NSTextAttachment *vipImageAttachment = [[NSTextAttachment alloc]init];
    vipImageAttachment.image = vipImage;
    vipImageAttachment.bounds = CGRectMake(0, 0, 13, 15);
 
    NSAttributedString *vipImageAttrStr = [NSAttributedString attributedStringWithAttachment:vipImageAttachment];
    [vipStr insertAttributedString:vipImageAttrStr atIndex:0];
    //设置字体和设置字体的范围
    [vipStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:15.0f] range:NSMakeRange(0, vipStr.length)];
    [self.noteLabel setAttributedText:vipStr];

2、图片和字体紧密相连、如何让图片和文字间有间隙呢？

修改

vipImageAttachment.bounds = CGRectMake(-5, 0, 13, 15);

会把图片前移、但是图片显示不全

3、设置图片间以及文字间距

新增代码

[vipStr addAttribute:NSKernAttributeName value:@(10) range:NSMakeRange(0, vipStr.length)];

设置文字间距效果图

效果并不理想，只有文字受到NSKernAttributeName属性影响。图片间距保持原样。

4、在每张图片后面添加空格，设置空格间文字间距、解决问题

    //设置空格文本
    [vipStr insertAttributedString:[[NSAttributedString alloc] initWithString:@" "] atIndex:1];
    //设置间距
    [vipStr addAttribute:NSKernAttributeName value:@(8)
                        range:NSMakeRange(1,1)];
