使用键盘将UITextField向上移动-Swift 4.2中的更改了吗? [英] Moving UITextField up with keyboard - changes in swift 4.2?

问题描述

当键盘会阻止它们的视图时，我具有向上移动某些文本字段的功能-我相信大家都知道这一点:

I had this function to move certain textfields upwards, when the keyboards would block their view - I'm sure you all know about this:

override func viewDidLoad() {
    super.viewDidLoad()

    let center: NotificationCenter = NotificationCenter.default
    center.addObserver(self, selector: #selector(keyboardDidShow(notification:)), name: NSNotification.Name?.UIKeyboardDidShow, object: nil)
    center.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: NSNotification.Name?.UIKeyboardWillHide, object: nil)

}

但是，当我最近更新到Swift 4.2时，这些方法停止了工作，并且提出了以下建议:

But when I recently updated to swift 4.2, these stopped working, and these suggestions came up:

将'UIKeyboardDidShow'替换为'UIResponder.keyboardDidShowNotification'&

Replace 'UIKeyboardDidShow' with 'UIResponder.keyboardDidShowNotification' &

将'UIKeyboardWillHide'替换为'UIResponder.keyboardWillHideNotification

Replace 'UIKeyboardWillHide' with 'UIResponder.keyboardWillHideNotification

但是当我按下"fix"时，出现错误(x2):

But when I pressed "fix", I get the error (x2):

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

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

对我来说，这似乎是个虫子?那个xCode不能接受它自己的改变?有人碰到这个，知道该怎么办吗?

It kind of seems like a bug to me? That xCode can't accept it's own changes?? Anybody came across this and knows what to do?

谢谢！

推荐答案

尝试一下

let notificationCenter = NotificationCenter.default
notificationCenter.addObserver(self, selector: #selector(adjustForKeyboard), name: UIResponder.keyboardWillHideNotification, object: nil)
notificationCenter.addObserver(self, selector: #selector(adjustForKeyboard), name: UIResponder.keyboardWillChangeFrameNotification object: nil)
