当 ViewController 消失时删除键盘通知 [英] Remove keyboard notification when ViewController disappears

问题描述

如何移除键盘通知?

我让观察者在键盘上打开和关闭.

I put observer on keyboard open and close.

我根据键盘是打开还是关闭来更改视图大小.

I change the view size depend on keyboard is open or close.

推荐答案

试试这个删除键盘打开显示观察者，

Try this to remove keyboard open show observers,

NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillHide, object: nil)

您应该根据您的要求在 deinit 或 viewDidDisappear 中删除观察者.

you should remove observers either in deinit Or viewDidDisappear as per your requirement.
