Add placeholder to textView iOS swift || Placeholder for UITextView iOS swift

-
Solution:

 In textfield we had an option for placeholder but it is not available for textView in XCode.No worries don't bang your heads on wall to handle this. I had the solution go ahead and enjoy.

First you have to create a label and add it to textview if textView is empty then show the label.


    var placeholderLabel : UILabel!



In viewdidload add the below code


        self.addPlaceHolderToTextView()

            placeholderLabel.isHidden = !textTV.text.isEmpty

Also add the below function in your class.

    // MARK: - PlaceHolders
    func addPlaceHolderToTextView(){
        placeholderLabel = UILabel()
        placeholderLabel.text = "Enter text"
        placeholderLabel.font = UIFont.systemFont(ofSize: (textTV.font?.pointSize)!) 
        placeholderLabel.sizeToFit()
        textTV.addSubview(placeholderLabel)
        placeholderLabel.frame.origin = CGPoint(x:5 , y: (textTV.font?.pointSize)! / 2 )
        placeholderLabel.textColor = UIColor(white: 0, alpha: 0.3)
        placeholderLabel.isHidden = !textTV.text.isEmpty
    }


In textview delegate method add the below code.Because if you edit the textview at runtime it will works.


 // MARK: - TtextView delegates
    func textViewDidChange(_ textView: UITextView) {
        placeholderLabel.isHidden = !textView.text.isEmpty
    }



That's it enjoyyyy.....
