类型"NSNotification.Name"没有成员"keyboardDidShowNotification" [英] Type 'NSNotification.Name' has no member 'keyboardDidShowNotification'

问题描述

我在Swift 4.2中遇到此错误

I'm getting this error with Swift 4.2

类型"NSNotification.Name"没有成员"keyboardDidShowNotification"

Type 'NSNotification.Name' has no member 'keyboardDidShowNotification'

这是我的代码:

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardDidShow(notification:)), name: NSNotification.Name.keyboardDidShowNotification, object: nil)

以下一项在Swift 4上运行正常，但在Swift 4.2上运行不正常

Following one was working fine with Swift 4 but not with Swift 4.2

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardDidShow(notification:)), name: NSNotification.Name.UIKeyboardDidShow, object: nil)

Apple文档参考: NSNotification.Name.keyboardDidShowNotification

Apple document Ref: NSNotification.Name.keyboardDidShowNotification

推荐答案

我相信您现在就这样使用它.

I believe you use it like this now.

NotificationCenter.default.addObserver(
    self, 
    selector: #selector(self.keyboardDidShow(notification:)), 
    name: UIResponder.keyboardDidShowNotification, object: nil) 

/* You can substitute UIResponder with any of it's subclass */

它在UIResponder doc 中列为类型属性.
