ios - 具有多个循环的 Json 解析

Question

如何在 objective-c 中循环遍历 json [{first set of values},{data->children->data->body} 的这一部分？

Json是

  [
      {
        "kind": "Listing"
      },
      {
        "kind": "Listing",
        "data": {
          "children": [
            {
              "data": {
                "body": "body1"
              }
            },

            {
              "data": {
                "body": "body2"
              }
            }
          ]
        }
      }
    ]

我当前的代码是

m_ArrList=[[NSMutableArray alloc]init];
    NSDictionary *infomation = [self dictionaryWithContentsOfJSONString:@"surveyquestion.json"];
    NSArray *array=[infomation objectForKey:@"data"];
    int ndx;
    NSLog(@"%@",array);
    for (ndx = 0; ndx < [array count]; ndx++) {
        NSDictionary *stream = (NSDictionary *)[array objectAtIndex:ndx];

        NSArray *string=[stream valueForKey:@"children"];

        //i am stuck here
    }

我在“//我被困在这里”时该怎么办？

您可能需要将 @"children" 字典的值添加到数组中，然后解析该数组以获取 children 中的数据

[childrenArray addObject:[stream objectForKey:@"children"]];

   // finally parse childrenArray
