How to check is UITextView is underlined or not iOS swift

Solution:

You cannot have any functions to check that.But you can test it by using the below method

    func attributes(value:Int) ->NSAttributedString {

        let textV = self.TextView

        let newTextView:UITextView! = UITextView.init()

        var attrs = [NSFontAttributeName : self.TextView.font,

                     NSForegroundColorAttributeName : self.TextView.textColor,

                     NSUnderlineStyleAttributeName : value] as! [String : Any]

        var attributedString = NSMutableAttributedString(string:"")

        let buttonTitleStr = NSMutableAttributedString(string:(self.TextView.text)!, attributes:attrs)

        attributedString.append(buttonTitleStr)

        newTextView.attributedText = attributedString

        return newTextView.attributedText

    }

In your textview you can check it by using the below code

            let attributedString = self.attributes(value: 1)

            if attributedString == self.TextView.attributedText! {

                

                self.TextView.attributedText = self.attributes(value: 0)

                btn.isSelected = false

                btn.backgroundColor = UIColor.clear

            } else {

                self.TextView.attributedText = attributedString

                btn.isSelected = true

                btn.backgroundColor = UIColor.white

            }

self.TextView is your textview that you want to check the underline
