There is no difference because neither exists for a NSMutableArray.
However, those methods exist for NSMutableDictionary. The difference between the 2 is this:
From apple: NSMutableDictionary
-setValue:forKey:
This method adds value and key to the dictionary using setObject:forKey:, unless value is nil in which case the method instead attempts to remove key using removeObjectForKey:.

3Not sure what 'complete dupe' means. The above is quoted (and cited) from apple's website. Unless you intended to vote down the question. Cheers. – Jeremy Aug 02 '12 at 14:21
