How can I hide keyboard accessory bar in WKWebview? Although there are some resources for UIWebView, I haven\'t been able to find one for WkWebview on Stackoverflow.

After Swift4

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillDisappear(_:)), name: UIResponder.keyboardWillHideNotification, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillAppear(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
     }

    @objc func keyboardWillAppear(_ notification: Notification) {
        //Do something here
        keyboardShowAndHide(true, notification: notification)
    }

    @objc func keyboardWillDisappear(_ notification: Notification) {
        //Do something here
        keyboardShowAndHide(false, notification: notification)
    }
    func keyboardShowAndHide(_ open: Bool, notification: Notification) {
      let userInfo = notification.userInfo ?? [:]
        let keyboardFrame = (userInfo[UIResponder.keyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue
      let height = (keyboardFrame.height + 20) * (open ? 1 : -1)
        WKWebView.scrollView.contentInset.bottom += height
        WKWebView.scrollView.scrollIndicatorInsets.bottom += height
    }

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        //remove keyboard Listener
        NotificationCenter.default.removeObserver(self)
    }
