我正在尝试使用以下代码将属性字符串转换为Data对象：
let text = self.textVIEw.attributedTextlet data = try text.data(from: NSMakeRange(0,text.length),documentAttributes: [:])
但是,这会引发以下错误：
Error Domain=NSCocoaErrorDomain Code=66062 "(null)"
任何想法这个错误意味着什么或可能导致这个？我正在使用最新的Xcode和iOS.谢谢.
解决方法 您需要指定要将属性字符串转换为哪种文档数据：NSPlainTextdocumentType // Plain text document. .txt documentNSHTMLTextdocumentType // Hypertext MarkuP Language .HTML document.NSRTFTextdocumentType // Rich text format document. .rtf document.NSRTFDTextdocumentType // Rich text format document with attachment. (.rtfd) document.
Xcode 8.3.2•Swift 3.1
let textVIEw = UITextVIEw()textVIEw.attributedText = NSAttributedString(string: "abc",attributes: [NSFontAttributename: UIFont(name: "Helvetica",size: 16)])if let attributedText = textVIEw.attributedText { do { let HTMLData = try attributedText.data(from: NSRange(location: 0,length: attributedText.length),documentAttributes: [NSdocumentTypedocumentAttribute: NSHTMLTextdocumentType]) let HTMLString = String(data: HTMLData,enCoding: .utf8) ?? "" } catch { print(error) }} 更新Xcode 9.0.1•Swift 4
let textVIEw = UITextVIEw()let attributes: [NSAttributedStringKey: Any] = [.Font: UIFont(name: "Helvetica",size: 16)!]textVIEw.attributedText = NSAttributedString(string: "abc",attributes: attributes)if let attributedText = textVIEw.attributedText { let documentAttributes: [NSAttributedString.documentAttributeKey: Any] = [.documentType: NSAttributedString.documentType.HTML] do { let HTMLData = try attributedText.data(from: NSRange(location: 0,documentAttributes: documentAttributes) let HTMLString = String(data: HTMLData,enCoding: .utf8) ?? "" print(HTMLString) } catch { print(error) }} 这将打印
