我从 Jason URl 获得了一些医生的数据。该数据显示了一些医生的单个医生位置，并显示了一些医生的多个位置。我怎样才能显示该数据。一旦请给我解决方案该数据显示在下面

          }    ]

我也给了帽子代码，请检查一下。

    - offC = [[[rr  objectForKey:@"doc_offices"]
           objectAtIndex:0]objectForKey:@"office_name"];  
 NSString *docOfficeID
           = [[[rr objectForKey:@"doc_offices"]objectAtIndex:0]objectForKey:@"office_id"];

这是我的解决方案：

        NSError *jsonParsingError = nil;
        NSMutableArray *arrDoctorInfo  = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:&jsonParsingError];
        for (NSMutableDictionary *data in arrDoctorInfo) {

            NSMutableArray *arrOffice = [data valueForKey:@"doc_offices"];
            NSString *strID = [data valueForKey:@"ID"];
            .
            .
            NSString *strdoc_profile_url = [data valueForKey:@"doc_profile_url"];
            for (NSMutableDictionary *dictDoffice in arrOffice) {
                NSString *strdictDoffice = [dictDoffice valueForKey:@"office_id"];
                .
                .
                NSString *stroffice_combined_name = [dictDoffice valueForKey:@"office_combined_name"];
            }

        }

为什么大家都推荐第三方框架？iOS 有原生 JSON 序列化工具：NSJSONSerialization. 这非常容易使用。例如：

dispatch_queue_t fetchQueue = dispatch_queue_create("nameOfYourQ", NULL); //here i create dispatch for connection (do not block UI!)
dispatch_async(fetchQueue, ^{ // block to fetch and parse
    NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://yourlink"]]; // NSData - connection for JSON
    id arrayOrDictionary = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil]; // parse NSData object to Dictionaries and Arrays.
    dispatch_async(dispatch_get_main_queue(), ^{
        [yourTableView reloadData]; // reload your view on main thread.
    });
});

这是一个非常简单的例子。我喜欢做的是NSURLConnectionDelegate用于下载数据，然后在委托方法NSJSONSerialization中用于解析数据。

等等，在您的 JSON 结构中，您有多个doc_offices键。所以我认为你真的有（得到office_id）数组 - 字典 - 字典 - 数组。

所以：

NSNumber *docOfficeID = [[[[rr objectAtIndex:0] objectForKey:@"doc_offices"] objectAtIndex:0] objectForKey:@"office_id"];

这不是一个NSString. 这是NSNumber
