I'm using this method:

I detect the Return key by checking whether the input string is equal to @"\n". But how would I detect the back-delete key? @"\b" doesn't do it. And I can't seem to find any docs that list these codes.

I haven't done any iPhone development myself, but I'd imagine that your problem is that you're looking for the wrong sort of change. Pressing Return inserts a newline, but pressing backspace doesn't insert a backspace. It removes a character. At a blind guess, maybe it'll show up as a range of length 1 being replaced with @""? _______________________________________________
