     // 提示字符串  tips:是服务器返回的HTML字符串
    lazy var tipsString : NSAttributedString? = {
        let data = tips?.data(using: String.Encoding.unicode) ?? Data()
        do {
            var  attributedString = try NSMutableAttributedString.init(data: data, options: [NSAttributedString.DocumentReadingOptionKey.documentType : NSAttributedString.DocumentType.html], documentAttributes: nil)
            //设置行间距，同样可以根据具体情况设置其他属性。
            let paraph = NSMutableParagraphStyle()
            paraph.lineSpacing = 10
            attributedString.addAttributes([NSAttributedStringKey.paragraphStyle: paraph], range: NSMakeRange(0, attributedString.length))
            return attributedString
        } catch let error {
            Mprint(error)
        }
        return nil
    }()
