How to change one value in NSMutableDictionary

I have a NSMutableDictionary with one key and it has the following values.

enter image description here

How can I change the value in item2 from 1 to 0? That's the only change I need.

The only way I have found is to recreate this whole key from scratch, change that one value and then delete that key and replace it with a new one. Is there any easier solution than that?

I will assume you get dict as an instance of NSMutableDictionary somehow:

NSMutableArray *tmp = [dict[@"07:00 AM.infoKey"] mutableCopy];
tmp[2] = @"0";
dict[@"07:00 AM.infoKey"] = tmp;

Unfortunately with nested arrays in dictionaries, the arrays aren't automatically mutable so there isn't any better method to doing so, like you observed.
