Objective C 从 .Net API 获取 MongoDB ObjectID 作为字符串，反之亦然

Question

我必须使用 return 的 .Net API 并使用 MongoDB ObjectId 作为结果和参数

例如服务器return

    _id": {
            "Timestamp": 1478679428,
            "Machine": 1031587,
            "Pid": 9124,
            "Increment": 2344035,
            "CreationTime": "/Date(1478679428000)/"
        }

以 NSDictionary 的形式表示 ObjectID 值 ObjectId("5822db840fbda323a423c463")

我的问题是：如何将上面的 NSDictionary _id 转换为 Objective C 中的字符串值 5822db840fbda323a423c463？

反之亦然，将 NSString 5822db840fbda323a423c463 转换为 NSDictionary 作为 api 参数发送 ?

注意：我不能改变api，只能消耗它

任何帮助将不胜感激

用于将 NSDictionary 从 API 结果序列化为 NSString

- (NSString *)NSStringFromNSDictionary:(NSDictionary *)dict
{
    long Timestamp = [[dict objectForKey:@"Timestamp"] longValue];
    long Machine = [[dict objectForKey:@"Machine"] longValue];
    long Pid = [[dict objectForKey:@"Pid"] longValue];
    long Increment = [[dict objectForKey:@"Increment"] longValue];

    NSString *oid = [NSString stringWithFormat:@"%08lx%06lx%04lx%06lx", Timestamp, Machine, Pid, Increment];

    return oid;
}

用于将 NSString 序列化回 .Net Mongo ObjectId，格式为 NSDictionary

- (NSDictionary *)NSStringFromNSDictionary:(NSString *)oid
{
    long Timestamp = strtol([[oid substringToIndex:8] UTF8String], NULL, 16);
    long Machine = strtol([[oid substringWithRange:NSMakeRange(8,6)] UTF8String], NULL, 16);
    long Pid = strtol([[oid substringWithRange:NSMakeRange(14,4)] UTF8String], NULL, 16);
    long Increment = strtol([[oid substringFromIndex:18] UTF8String], NULL, 16);


    NSDictionary * dict = @{@"Timestamp": [NSNumber numberWithLong:Timestamp]
                        ,@"Machine": [NSNumber numberWithLong:Machine]
                        ,@"Pid": [NSNumber numberWithLong:Pid]
                        ,@"Increment": [NSNumber numberWithLong:Increment]
                        ,@"CreationTime": [NSString stringWithFormat:@"/Date(%ld)/",Timestamp*1000]
                        };

    return dict;
}
