You may already know this, but you can also enumerate over NSDictionary entries using enumerateKeysAndObjectsUsingBlock: [1] and enumerateKeysAndObjectsWithOpt

You may already know this, but you can also enumerate over NSDictionary entries using enumerateKeysAndObjectsUsingBlock: [1] and enumerateKeysAndObjectsWithOptions:usingBlock: [2]. The latter giving you the ability to enumerate in reverse order or spread the enumeration across multiple cores using Grand Central Dispatch.
