iOS 11 - Keyboard Height is returning 0 in keyboard notification
Use this:
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;For Swift, you can use:
let keyboardSize = (notification.userInfo![UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue.size
Replace UIKeyboardFrameBeginUserInfoKey
with
UIKeyboardFrameEndUserInfoKey
The below is from Apple Docs.
UIKeyboardFrameBeginUserInfoKey- The key for an NSValue object containing a CGRect that identifies the start frame of the keyboard in screen coordinates.
UIKeyboardFrameEndUserInfoKey - The key for an NSValue object containing a CGRect that identifies the end frame of the keyboard in screen coordinates.
Try this:
Replace UIKeyboardFrameBeginUserInfoKey with UIKeyboardFrameEndUserInfoKey
