import Keyboardy
  • Register for keyboard notifications

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    unregisterFromKeyboardNotifications()
}
  • Implement KeyboardStateDelegate
extension ViewController: KeyboardStateDelegate {

    func keyboardWillTransition(_ state: KeyboardState) {
        // keyboard will show or hide
    }

    func keyboardTransitionAnimation(_ state: KeyboardState) {
        switch state {
        case .activeWithHeight(let height):
            textFieldContainerBottomConstraint.constant = height
        case .hidden:
            textFieldContainerBottomConstraint.constant = 0.0
        }

        view.layoutIfNeeded()
    }

    func keyboardDidTransition(_ state: KeyboardState) {
        // keyboard animation finished
    }
}
