Placeholder in UITextView

Question

My application uses an UITextView. Now I want the UITextView to have a placeholder similar to the one you can set for an UITextField.<

Answer 1

Simple Swift 3 solution

Add UITextViewDelegate to your class

Set yourTextView.delegate = self

Create placeholderLabel and position it inside yourTextView

Now just animate placeholderLabel.alpha on textViewDidChange:

  func textViewDidChange(_ textView: UITextView) {
    let newAlpha: CGFloat = textView.text.isEmpty ? 1 : 0
    if placeholderLabel.alpha != newAlpha {
      UIView.animate(withDuration: 0.3) {
        self.placeholderLabel.alpha = newAlpha
      }
    }
  }

you might have to play with placeholderLabel position to set it up right, but that shouldn't be too hard
