当某些特定的文本字段被键盘隐藏时如何向上移动表格视图？

Question

我有一个表格视图，表格视图单元格中有文本字段's.when我尝试输入文本，特别是在表格视图底部的文本字段中，然后文本字段被键盘隐藏。我正在尝试使用下面的代码来解决这个问题。

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

   @objc func keyBoardWillChange(notification : Notification)
    {
        print("Keyboard will show :\(notification.name.rawValue)")
        let cell = deliveryTableView.cellForRow(at: IndexPath.init(row: 8, section: 0))
        
        view.frame.origin.y = -175
    }/*
    @objc func KeyBoardWillHide(notification : Notification)
    {
        UIView.animateKeyframes(withDuration: 0.25, delay: 0.0, options: UIView.KeyframeAnimationOptions.allowUserInteraction, animations: {
            self.view.frame = CGRect(x: 0, y: 0, width: self.view.bounds.width, height: self.view.bounds.height)
        }, completion: nil)
    }*/
    deinit {
        NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardDidShowNotification, object: nil)
        NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
        NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillChangeFrameNotification, object: nil)
    }

但问题是，即使在单击第一个文本字段时，tableview 也会向上移动，这看起来不太好。但我希望 tableview 仅在底部存在文本字段的情况下向上移动。

Answer 1

使用 IQKeyboardManager 和 appdelegate.It 中的一行代码即可处理键盘。

步骤 1) 在 pod-file 和运行中添加 pod 'IQKeyboardManager' pod install

步骤2)在appdelegate的didFinishLaunchingWithOptions方法中写这段代码启用IQKeyboardManager

IQKeyboardManager.shared.enable = 真
