How to add a detail label to UIAlertAction?

Question

I'm studing iOS, and I got a question. How should I do to add a detail label to UIAlertAction? Like UITableViewCell with UITableViewCellStyleSubtitle.

Thanks.

let attributedString = NSAttributedString(string: "My Message",
     attributes: [NSAttributedStringKey.font : UIFont(name: "Avenir-Light", size: 20)!])

let alert = UIAlertController(title: "Title", message: "", preferredStyle: .alert)

alert.setValue(attributedString, forKey: "attributedMessage")

let cancelAction = UIAlertAction(title: "OK", style: .default, handler: nil)

alert.addAction(cancelAction)

present(alert, animated: true, completion: nil)

try this one..

Sorrr, what I need is UIAlertAction, not UIAlertController. – Acedia Nov 05 '18 at 09:41
just change below line with let alert = UIAlertController(title: "Title", message: "", preferredStyle: .actionSheet) – Abu Ul Hassan Nov 05 '18 at 10:39

You can not add detailedText(two labels) in UIAlertAction. But Instead of that you can make your own customized alert view and action buttons. If you don't have time, you can search for third party libraries.

Also if UIAlertAction has ability to set attributed text, you could append two lines(by adding "\n" in NSAttributedString with small font to display like detailLabel) of text as UIAlertAction title. But unfortunately there is no public API to set attributed String as UIAlertAction title. But there is a private API as mentioned in this answer UIAlertController custom font, size, color
