HTML Format in Uitextview

HTML Format in UITextView

The problem there is that you have to change the Character Encoding options from NSUnicodeStringEncoding to NSUTF8StringEncoding to load your of your html the proper way. I think you should create a string extension read-only computed property to convert your html code to attributed string:

Xcode 8.3.1 • Swift 3.1

extension Data {
    var attributedString: NSAttributedString? {
        do {
            return try NSAttributedString(data: self, options:[NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: String.Encoding.utf8.rawValue], documentAttributes: nil)
        } catch {
            print(error)
        }
        return nil
    }
}
extension String {
    var data: Data {
        return Data(utf8)
    }
}

let htmlStringCode = "Für mehr Informationen klicken sie <a href=\"http://www.samplelink.com/subpage.php?id=8\">here</a>"

htmlStringCode.data.attributedString?.string ?? ""  // "Für mehr Informationen klicken sie here"

in your case

yourTextView.attributedText = htmlStringCode.data.attributedString

Display html text in uitextview

Use a UIWebView on iOS 5-.

On iOS 6+ you can use UITextView.attributedString, see https://stackoverflow.com/a/20996085 for how.

There's also an undocumented -[UITextView setContentToHTMLString:] method. Do not use this if you want to submit to AppStore.

Displaying HTML content in UITextView

Try This

var attrStr = try! NSAttributedString(
            data: "<b><i>text</i></b>".data(using: String.Encoding.unicode, allowLossyConversion: true)!,
            options:[NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil)
        YOUR_TEXTVIEW.attributedText = attrStr

Swift: Display HTML data in a label or textView

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

How to maintain indentations of HTML content in UITextView in Swift?

Just if you receive Html data Display it by using attributedText

Convert html to AttributedString :

    // Read Html of Your example From Bundle

    guard let  htmlFile =  Bundle.main.path(forResource: "dataHtml", ofType: "html") else { return}

    // Safe convert html to string
    guard let  html =  try? String(contentsOfFile: htmlFile, encoding: String.Encoding.utf8)else { return}

    let options = [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html]

    // Safe string  to Data

    guard let  htmlData =  NSString(string: html).data(using: String.Encoding.unicode.rawValue) else { return}

    // Safe attributedString from data
    guard let  attributedString =  try? NSAttributedString(data: htmlData, options: options, documentAttributes: nil) else { return}

    textView.attributedText = attributedString
    textView.textColor = .red // you can comment  or change font and color

Result on your example :

HTML string in UITextView AppStore rejection

Part 1 - App Store rejection will only be because of one of the reasons in the App Review Guidelines. There's plenty to worry about there without considering how you format some text. But I doubt your text formatting alone would get you rejected.

Check this and read it carefully: https://developer.apple.com/app-store/review/guidelines/

Part 2 - Is it a UITextField or a UITextView. If your text is getting smaller than you've set in a UITextField it's probably because you have adjustsFontSizeToFitWidth set to YES and the text is wider than the text field. Fixing that would require us to see more of you code and maybe a screenshot.

If it's a UITextView check this answer: How to change the uitextview font size. See if you have it set to "Selectable" in the storyboard.

But you might want to make it just a label.
