I’m writing an app based around a calculator-like UI. On an iPad, I’d like the number UIButtons on my calculator UI to respond to the numbers on the external keyboard. I have no text input anywhere in the app, and I’d never want an on-screen keyboard to appear. How do I get my UIButtons to respond to specific key presses as if they’d been touched?
I’d say create a hidden UITextField with the delegate set, make it become the first responder upon viewDidLoad. The keyboard won’t appear when a bluetooth keyboard is connected as far as I know, then just check what characters are typed in the shouldChangecharactersInRange and activate the right buttons accordingly.
EDIT: a quick example I just made, https://github.com/benjaminq42/buttonTest , if you wish to have a highlight animation of some sorts you need to create a custom UIButton class. You can use ‘setHighlighted’ but that ‘sticks’.
