An NSMutableDictionary (or NSDictionary) can have any object as the value: strings, dictionaries, arrays, etc. Regardless of the type, you retrieve it exactly the same. If you store a dictionary in there, you just need to drill in one more level to see that dictionary's data (you'll have to cast it to a dictionary though).

Psuedo code ensuing...

Dictionary a = ...;
a[@"keyA"] = "hi A";
Dictionary b = ...;
b[@"keyB"] = a;

// You now have the dictionary "a" stored inside dictionary "b" with a key of "keyB".

Dictionary c = b[@"keyB"];

// Dictionary c is now, essentially, Dictionary a

// c[@"keyA"] will return to you "hi A"
