swift - iOSDropDown : Type 'UIResponder' has no member 'NSNotification'

Question

更新到 Catalina 和 pod update 后我收到错误

Type 'UIResponder' has no member 'NSNotification'

这是给 iOSDropDown 的

if isSearchEnable && handleKeyboard{
        NotificationCenter.default.addObserver(forName: UIResponder.NSNotification.Name.UIKeyboardWillShow, object: nil, queue: nil) { (notification) in
            if self.isFirstResponder{
            let userInfo:NSDictionary = notification.userInfo! as NSDictionary
                let keyboardFrame:NSValue = userInfo.value(forKey: UIResponder.UIKeyboardFrameEndUserInfoKey) as! NSValue
            let keyboardRectangle = keyboardFrame.cgRectValue
            self.keyboardHeight = keyboardRectangle.height
                if !self.isSelected{
                    self.showList()
                }
            }

        }
        NotificationCenter.default.addObserver(forName: UIResponder.NSNotification.Name.UIKeyboardWillHide, object: nil, queue: nil) { (notification) in
            if self.isFirstResponder{
            self.keyboardHeight = 0
            }
        }
    }

您现在将在UIResponder 上直接使用keyboardWillShowNotification，如前所述here在类型属性下，

NotificationCenter.default.addObserver(forName: UIResponder.keyboardWillShowNotification, object: nil, queue: nil)

注意:由于错误出现在外部库中，您可以fork 库，解决问题并在 podfile 中指向您的 fork 版本。或者，您可以选择在本地计算机上进行更改，但每次您执行 pod update 时它都会被覆盖。
