I would like to determine the height of the inputAccessoryView that is showing with the current keyboard. I could probably track back through the firstResponder, if I need to, but I am looking for something more direct. If the keyboard is showing with an inputAccessoryView, return its height, otherwise return zero.
I am using keyboard notifications to help get the keyboard size, based on the code shown in this SO answer. Once I know the keyboard is showing, I want to get info on the input accessory view.
