Swift 4转换html为字符串文本

Swift 4可以添加extension来把html转换为字符串。

String添加扩展

extension String {
    var html2AttributedString: NSAttributedString? {
        do {
            return try NSAttributedString(data: Data(utf8),
                                          options: [.documentType: NSAttributedString.DocumentType.html,
                                                    .characterEncoding: String.Encoding.utf8.rawValue],
                                          documentAttributes: nil)
        } catch {
            print("error: ", error)
            return nil
        }
    }
    var html2String: String {
        return html2AttributedString?.string ?? ""
    }
}

NSAttributedString需要加上选项

.documentType: NSAttributedString.DocumentType.html

使用

let str = htmlData.html2String
