UIAlertController custom font, size, color

Question

I am using new UIAlertController for showing alerts. I have this code:

// nil titles break alert interface on iOS 8.0, so we\'ll be using empty strings
UIAle         


        

Answer 1

Swift 5.0

let titleAttrString = NSMutableAttributedString(string: "This is a title", attributes: [NSAttributedString.Key.font: UIFont(name: "CustomFontName", size: 17) as Any])
let messageAttrString = NSMutableAttributedString(string: "This is a message", attributes: [NSAttributedString.Key.font: UIFont(name: "CustomFontName", size: 13) as Any])

alertController.setValue(titleAttrString, forKey: "attributedTitle")
alertController.setValue(messageAttrString, forKey: "attributedMessage")
