Swift: Display HTML data in a label or textView

Question

I have some HTML data, which contains headings, paragraphs , images and lists tags.

Is there a way to display this data in one UITextView or UILabel?

Answer 1

For Swift 5:

extension String {     var htmlToAttributedString: NSAttributedString? {         guard let data = data(using: .utf8) else { return nil }         do {             return try NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding:String.Encoding.utf8.rawValue], documentAttributes: nil)         } catch {             return nil         }     }     var htmlToString: String {         return htmlToAttributedString?.string ?? ""     } } 

Then, whenever you want to put HTML text in a UITextView use:

textView.attributedText = htmlText.htmlToAttributedString 

Answer 2

Here is a Swift 3 version:

private func getHtmlLabel(text: String) -> UILabel {     let label = UILabel()     label.numberOfLines = 0     label.lineBreakMode = .byWordWrapping     label.attributedString = stringFromHtml(string: text)     return label }  private func stringFromHtml(string: String) -> NSAttributedString? {     do {         let data = string.data(using: String.Encoding.utf8, allowLossyConversion: true)         if let d = data {             let str = try NSAttributedString(data: d,                                              options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType],                                              documentAttributes: nil)             return str         }     } catch {     }     return nil } 

I found issues with some of the other answers here and it took me a bit to get this right. I set the line break mode and number of lines so that the label sized appropriately when the HTML spanned multiple lines.
