GrowingTextview is just a textview, download the example to see how to use it as a input toolbar like other instant messaging apps.

Using GrowingTextview programmatically

let textView = GrowingTextView()
textView.delegate = self

Using GrowingTextview in Storyboard

  1. Drag a TextView into Storyboard.
  2. Set class to "GrowingTextView".
  3. Set delegate to it's view controller.

Sometime the view controller may incorrectly adjust the inset of textview automatically. To avoid this, set automaticallyAdjustsScrollViewInsets to false

override func viewDidLoad() {
	automaticallyAdjustsScrollViewInsets = false


Parameter Type Description Default
maxLength Int Maximum text length. Exceeded text will be trimmed. 0 means no limit. 0
trimWhiteSpaceWhenEndEditing Bool Trim white space and new line characters when textview did end editing. true
placeholder String? Placeholder text. nil
placeholderColor UIColor Placeholder text color. UIColor(white: 0.8, alpha: 1.0)
attributedPlaceholder NSAttributedString? Attributed Placeholder text. nil
minHeight CGFloat Minimum height of textview. 0.0
maxHeight CGFloat Maximum height of textview. 0.0


textView.maxLength = 140
textView.trimWhiteSpaceWhenEndEditing = false
textView.placeholder = "Say something..."
textView.placeholderColor = UIColor(white: 0.8, alpha: 1.0)
textView.minHeight = 25.0
textView.maxHeight = 70.0
textView.backgroundColor = UIColor.whiteColor()
textView.layer.cornerRadius = 4.0


  1. Adopt GrowingTextViewDelegate instead of UITextViewDelegate.
  2. Implement textViewDidChangeHeight.
  3. Call layoutIfNeeded() on superview inside the animation.
class ViewController: UIViewController, GrowingTextViewDelegate {
	func textViewDidChangeHeight(_ textView: GrowingTextView, height: CGFloat) {
	   UIView.animate(withDuration: 0.2) {


GrowingTextViewDelegate is inherited from UITextViewDelegate. You may use it's delegate function as a normal UITextView.

class ViewController: UIViewController, GrowingTextViewDelegate {
    func textViewDidChange(_ textView: UITextView) {
    func textViewDidEndEditing(_ textView: UITextView) {
