获得键盘高度不适用于IOS 11 beta [英] Get the height of keyboard doesn't work on IOS 11 beta

问题描述

我有以下代码可用于IOS 10，但现在它在IOS 11测试版上运行时不再有效。

I have the following code which worked on IOS 10, but now it doesn't work anymore when running on IOS 11 beta.

if let userInfo = notification.userInfo {
    if let keyboardSize = (userInfo[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        print(keyboardSize)
    }
}

这是我打印尺码时得到的结果：

This is what I get when I print the size:

(0.0, 0.0, 0.0, 0.0)
(0.0, 736.0, 414.0, 0.0)

任何人都知道为什么停止工作？或者，如果我有其他选择来获得键盘大小？

Anyone knows why this has stopped working ? Or if I have any other alternatives to get the keyboard size ?

推荐答案

使用 UIKeyboardFrameEndUserInfoKey 而不是 UIKeyboardFrameBeginUserInfoKey

因此，将代码更改为以下内容将解决您的问题：

So changing your code to the following will fix your issue:

if let userInfo = notification.userInfo {
    if let keyboardSize = (userInfo[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        print(keyboardSize)
    }
}
