While building 55Prophets for iOS (you can download it here), I wanted to allow deep linking into the app. For example, I wanted users to be able to share links to specific questions. When someone accessed the link, I wanted the app to take them directly to that question, instead of dropping them into the home screen that appears on a normal app launch. However, the question page is typically several layers deep into a navigation stack. So how do you link directly into a view controller like this?
