ios - NSMutableURLRequest，JSON 转换为 NSDictionary

Question

我正在通过“JSON”从 NSMutableURLRequest 中检索数据。数据返回，我通过以下方式转换为字典:

 NSDictionary* json = [NSJSONSerialization JSONObjectWithData:companyData //1
                                                     options:kNilOptions
                                                       error:&e];

我遇到的问题是，当我获取数据并返回时:

 NSArray* parameterInfo = [json objectForKey:@"parameters"];

返回的数据是下面的形式，显示为 NSDictionary 但我不能为我的生活弄清楚如何将其转换为我可以读取的数据.意思是，“parameterInfo 数组”项目，我如何将其作为 NSDictionary 读取，然后能够以编程方式使用数据。

从下面可以看出，“KEY”是一个字典。

我希望这是有道理的。任何帮助是极大的赞赏。

忘掉整个 objectForKey 吧，它只是

NSArray *values = json[@"parameters"][@"key"][@"value];
