I have a class called TestViewController which asks user for the english translation of a foreign word. User taps on a UITextField which brings up the keyboard, and user types in their answer. The answer is checked after user taps the return key. My problem is that the keyboard is dismised each time the return key is tapped and answer is checked. User has to tap inside UITextField each time they want to submit the next answer. My question is, how to keep the keyboard present at all times.
I've tried commenting out line 75, which keeps keyboard up all the time, but the users answer doesn't get checked so they can move on to the next question.
