//传入文字 自动图片放在左边文字紧接着后排排布
-(void)setAttrDetailLabelWithTitle:(NSString *)title
{

    NSMutableAttributedString *attri = [[NSMutableAttributedString alloc] init];
    // 添加表情
    NSTextAttachment *attch = [[NSTextAttachment alloc] init];
    // 表情图片
    UIImage *image =[UIImage imageNamed:@"zp"];
        image = [UIImage imageWithCGImage:image.CGImage scale:2 orientation:UIImageOrientationUp];

    attch.image = image;

    // 设置图片大小 和 微调图片的位置
    attch.bounds = CGRectMake(0, -2, image.size.width, image.size.height);

    // 创建带有图片的富文本
    NSAttributedString *string = [NSAttributedString attributedStringWithAttachment:attch];
    [attri appendAttributedString:string];

    [attri appendAttributedString:[[NSAttributedString alloc] initWithString:@" "]];

    [attri appendAttributedString:[[NSAttributedString alloc] initWithString:title]];

    // 用label的attributedText属性来使用富文本
    self.despLabel.attributedText = attri;
