Vertically align UIImageView added as rightView of textfield with the text of skyfloatinglabeltextfield

Question

I have added a checkmarkImageView as rightview of a skyfloatinglabeltextfield as follows:

let checkmark = UIImage(named: "checkmark") 
checkmarkImageView = UIImageView(image: checkmark)
checkmarkImageView?.frame = CGRect(x: 0.0, y: 0.0, width: 20.0, height: 20.0)
textfield?.rightView = checkmarkImageView
textfield?.rightViewMode = .always
editView.addSubview(textfield!)

It is not aligning vertically centre with the text of the textfield. How do I achieve that?

Answer 1

change the frame.offsetBy, I used textfield Border Style as Plain

    let rightVie = UIView()
    rightVie.backgroundColor = UIColor.clear

   checkmarkImageView = UIImageView(image: UIImage(named: "checkmark")) // use your imageView
  //  checkmarkImageView?.frame = CGRect(x: 0.0, y: 0.0, width: 20.0, height: 20.0)
   checkmarkImageView.frame = checkmarkImageView.frame.offsetBy(dx: 0, dy: -1 + textfield.titleHeight()/2)
    rightVie.frame = checkmarkImageView.frame
    rightVie.addSubview(checkmarkImageView)
    //use your textfield name
    textfield?.rightView = rightVie
    textfield?.rightViewMode = .always

output
