Hardware keyboard and APNumberPad

[tomjtobin]

If a user uses an external keyboard (more applicable to iPad), is there a way to let number keystrokes on the keyboard fire the appropriate key buttons in APNumberPad?

Sorry about not replying to your issue for a long time.

In the simplest case, you can do manually turn on highlighted state of the buttons in number pad in UITextField delegates method - textField:shouldChangeCharactersInRange:replacementString:corresponding to replacementString. But this solution doesn't respect edge cases such as holding keys on external keyboard, fast typing and so on (perhaps this can be solved by calculating the delay between calls of delegate method and setting animation duration values based on this calculations).

But first of all, you need to detect an external keyboard (there is no built-in way to do it in iOS), you can follow so-question http://stackoverflow.com/questions/2893267/how-can-i-detect-if-an-external-keyboard-is-present-on-an-ipad
