Convert NSArray into array of JSON objects

Question

I'd like to create a JSON array of objects from the resultsArray.

NSMutableArray *resultsArray = [NSMutableArray array];
FMResultSet *resultsSet = [database executeQuery:queryString];
while ([resultsSet next]) {
    [resultsArray addObject:[resultsSet resultDictionary]];
}

For clarification, I'm using FMDB to query a database. I'm then storing the resulting objects within the resultsArray. From here I want to convert that results array into a JSON array of objects.

Are you asking how to use a JSON library in cocoa or something else? It's far from clear. — djromero

You can use NSJSONSerialization class to create a JSON file from your dictionary using the class method

NSData * JSONData = [NSJSONSerialization dataWithJSONObject:resultsArray
                                                    options:kNilOptions
                                                      error:&error];

For more info look at apple documentation
