Get the height of keyboard doesn't work on IOS 11 beta

Question

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          


        

Answer 1

Use UIKeyboardFrameEndUserInfoKey instead of UIKeyboardFrameBeginUserInfoKey

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)
    }
}
