label 划线问题

        //中划线

    NSDictionary *attribtDic = @{NSStrikethroughStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle]};

        //下划线

        NSDictionary *attribtDic = @{NSUnderlineStyleAttributeName: [NSNumbernumberWithInteger:NSUnderlineStyleSingle]};

  

        NSMutableAttributedString *attribtStr = [[NSMutableAttributedString alloc]initWithString:oldStrattributes:attribtDic];

       [attribtStr addAttribute:NSStrikethroughColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, oldStr.length)];//删除线红色

        oldPriceLabel.attributedText = attribtStr;
