I'm sure you have solved this at this point, but I found it convenient to write a recursive utility class function that recursively logs every key of a dictionary:

/**
 *  Recursively logs the keys and values of each object in the dictionary,
 *  along with the class of the value.
 *
 *  @param dict The dictionary to inspect
 */
+ (void)logDictionaryKeys:(NSDictionary*)dict {
    for (id key in dict) {
        if ([dict[key] isKindOfClass:[NSDictionary class]]) {
            [self logDictionaryKeys:dict[key]];
        }else {
            NSLog(@"Key: %@", key);
            NSLog(@"Value: %@ (%@)", dict[key], [dict[key] class]);
        }
    }

    return;
}
