Ios 键盘显示额外的空间

原始屏幕截图：

  func addKeyboardObservers() {
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
}

// MARK: - remove Keyboard Observers
func removeKeyboardObservers() {
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
}

// MARK: - keyboard show
@objc func keyboardWillShow(_ notification: Notification) {
    if let keyboardFrame: NSValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue {
        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height - bottomLayoutGuide.length
        UIView.animate(withDuration: 0.25, animations: {() -> Void in
            self.bottomConstraint.constant = keyboardHeight
            self.view.layoutIfNeeded()
        }, completion: nil)
    }
}

// MARK: - keyboard hide
@objc func keyboardWillHide(_ notification: Notification) {
    view.layoutIfNeeded()
 }

1.当键盘不可见时：

这很好

2。问题是当键盘出现时，上述图像从文本视图和键盘的原始位置移到上方，如下所示：

以下是我试图做的：

代码：

  func addKeyboardObservers() {
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
}

// MARK: - remove Keyboard Observers
func removeKeyboardObservers() {
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
}

// MARK: - keyboard show
@objc func keyboardWillShow(_ notification: Notification) {
    if let keyboardFrame: NSValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue {
        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height - bottomLayoutGuide.length
        UIView.animate(withDuration: 0.25, animations: {() -> Void in
            self.bottomConstraint.constant = keyboardHeight
            self.view.layoutIfNeeded()
        }, completion: nil)
    }
}

// MARK: - keyboard hide
@objc func keyboardWillHide(_ notification: Notification) {
    view.layoutIfNeeded()
 }

当我使用此代码时，请显示下面给出的空白屏幕截图：

当我评论这些行时，屏幕截图如下：

// MARK: - keyboard show

@objc func keyboardWillShow(_ notification: Notification) {
   // if let keyboardFrame: NSValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue {
    //    let keyboardRectangle = keyboardFrame.cgRectValue
     //   let keyboardHeight = keyboardRectangle.height - bottomLayoutGuide.length
      //  UIView.animate(withDuration: 0.25, animations: {() -> Void in
       //     self.bottomConstraint.constant = keyboardHeight
       //     self.view.layoutIfNeeded()
      // }, completion: nil)
  //  }
}

这是我的主要情节提要屏幕截图：

有人能给我解释一下如何解决这个问题吗？我已经尝试过解决这个问题，但还没有结果

任何帮助都将不胜感激

提前感谢。

使用以下属性在键盘上隐藏建议拼写视图，希望对您有所帮助

textField.autocorrectionType = .no

你会经常在新手机上看到这种“间隙”，因为它们使用“安全区域插入”，要减小对象和键盘之间的间隙，你需要做两件事

获取键盘高度

获取视图的安全区域，您可以将其放入这样的变量中

不只是减少这两个值，您将获得完美的输出

如果使用约束，则可以更改底部锚点的常数

在本例中，我将使用TableView，但您可以将其应用于任何对象

var bottomAnchor: NSLayoutConstraint? // Creating variable for bottom constraint

// Setting Constraints
bottomAnchor = tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 0)
bottomAnchor.isActive = true

// Modifying Constraint later (When Keyboard is Shown)
bottomAnchor.constant = keyboardFrame.height - safeArea

如果要修改UIEDGEINSET，则只需将底部值减小到安全区域即可

// When Keyboard is Shown
// E.g.
tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardFrame.height - safeArea, right: 0)

为什么要尝试手动更新视图？为此使用IQKeyboardManager什么是

self.bottomConstraint

？@AtulParmar i IQKeyboardManager使用，但相同result@mag_zbc这是我的错误。您想从键盘隐藏建议拼写视图吗？如果您使用了IQKeyboardManager，请禁用此视图并通过普通键盘
