I'm looking to create a reference app for iOS that drills-down through categories to display a Detail viewcontroller containing the topic information.
I've been studying Xcode for a while but can't quite find the advice I need to focus my study in this area.
The drill-down will be, at most, 5 levels. What is the best database technology to use for something quite low level?
What should I be targeting in my searches to find tutorials that can help me in this specific area?
