iOS: How to detect the escape/control keys on a hardware bluetooth keyboard?

Question

I\'m trying to figure out how to detect that the Escape (and other key combinations like Ctrl and alt) have been pressed on a bluetooth keyboard attached to an iOS device.

Answer 1

There are no public APIs for what you intend to accomplish, so this may lead to a rejection.

If you are willing to risk it, you can try this. Wich basically intercepts all events sent to your App by overwriting sendEvent: in your UIApplication.
