These aren’t CouchDB questions, they’re general Cocoa questions. Sounds like you should
read documentation on NSArray and NSDictionary, or get a good book on iOS or Mac development.
This is kind of off-topic for this list. Apple’s cocoa-dev mailing list (
is a better place, *if* you’ve read through docs and still have issues.

You get items from an array using [array objectAtIndex:], and from a dictionary using [dict
(Actually in Xcode 4.6 or later you can access them as in JavaScript/Python/Ruby/etc., simply
as “array[index]” or “dict[key]”.)
Iteration looks like "for (id item in arrayOrDict) { … }"
Iterating a dictionary gives you the keys, so you’ll need to look those up as above to get
the corresponding values.
