推荐答案

无需任何计算，使用下面的代码就能完美运行，

No need any calculations, use below code it will work perfectly,

override func viewDidLoad() {
    super.viewDidLoad()

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

 func keyboardWillShow(_ notification:Notification) {

    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        reimbursementTableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0)
    }
}

func keyboardWillHide(_ notification:Notification) {

    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        reimbursementTableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0)
    }
}
