jin8k,
There's a few things that come to mind. First off, using the UIToolbar is different from using buttons... I haven't really played around with them much, but I think with a little searching you can find out how to trigger the action based upon what button the user presses (it's different from how buttons are treated, but not by much).
Regarding storing the information after you find out what someone pressed, I'd suggest glancing at this video tutorial:
Welcome to the iPhone Development Central Website!
It covers NSMutableArray which is a modifiable array you can use to dynamically store your answers. I'm assuming that what you're trying to do is get a user to the end of the quiz before telling them how many they got right or wrong. That just means you'll need to do something simple at the end like:
Code:
i = 0
rightanswers = 0
for i++{
if ((questionArray objectAtIndex:i) == (answerArray objectAtIndex:i)){
rightanswers = rightanswers++;
}
}
