NSDictionary 的 description 返回格式为什么不是{} 而是[]啊

[marujun]

如题，对应的代码如下，dic.count 为0 时是正确的

case YYEncodingTypeNSDictionary: 
case YYEncodingTypeNSMutableDictionary: {
            NSDictionary *dic = (id)model;
            NSMutableString *desc = [NSMutableString new];
            if (dic.count == 0) {
                return [desc stringByAppendingString:@"{}"];
            } else {
                NSArray *keys = dic.allKeys;

                [desc appendFormat:@"[\n"];
                for (NSUInteger i = 0, max = keys.count; i < max; i++) {
                    NSString *key = keys[i];
                    NSObject *value = dic[key];
                    [desc appendString:@"    "];
                    [desc appendFormat:@"%@ = %@",key, ModelDescriptionAddIndent(ModelDescription(value).mutableCopy, 1)];
                    [desc appendString:(i + 1 == max) ? @"\n" : @";\n"];
                }
                [desc appendString:@"]"];
            }
            return desc;
        }
