ios - 键盘打开时移动菜单(快速)

Question

我的函数“keyboardWillShown”有问题。所以我想要的是菜单打开时，菜单正好出现在键盘上方。它可以在Iphone 8 plus，8、7、6上完美运行。但是，当我在模拟器上运行Iphone 11时，结果如下。

Constrains

这是我的代码:

@objc func keyboardWillShown(notification: NSNotification) {
    let info = notification.userInfo!
    let keyboardFrame: CGRect = (info[UIResponder.keyboardFrameEndUserInfoKey] as! NSValue).cgRectValue

    UIView.animate(withDuration: 0.1, animations: { () -> Void in
        self.keyboardConstrains.constant = keyboardFrame.size.height
    })
}

通话功能

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

override func viewWillDisappear(_ animated: Bool) {
    NotificationCenter.default.removeObserver( self,name:  UIResponder.keyboardWillShowNotification, object: nil )
}

您可以根据屏幕尺寸设置约束

if self.view.height >= 800{ //For bigger screens (X ,11)
    self.keyboardConstrains.constant = keyboardFrame.size.height - 50
} else {
    self.keyboardConstrains.constant = keyboardFrame.size.height
}
