1.继承 UITextViewDelegate
2.

NotificationCenter.default.addObserver(self, selector: #selector(TextViewController.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(TextViewController.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)

    func keyboardWillShow(notification:NSNotification) {

            if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
                //self.contentTextView.frame.origin.y -= keyboardSize.height
                self.contentTextView.contentInset.bottom = keyboardSize.height

            }

    }

    func keyboardWillHide(notification:NSNotification) {

            if ((notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue) != nil {
                self.contentTextView.contentInset.bottom = 0
                //keyboardIsPresent = false
            }

    }
