I would genuinely like to be able to help with this kind of app design logical flow question but I’m afraid it’s beyond what I can offer support for. If you definitely need to exit your loop for every question, you don’t really want a loop but some kind of delegate callback or NSNotification pattern. But there is also no inherent reason that you should have to exit a loop in order to call other functionality in the course of your app. I have to recommend investigating patterns for logical flow in an app — I think there is some good stuff at the Apple developer site, and please feel free to bring more questions here that are about OpenEars specifically.
