ios - 如何解析这样的json数组？

Question

我在尝试解析以下 json 数组时遇到了困难。如何解析它。网络上的其他答案似乎没有解决我的问题。

{
  "status": 1,
  "value": {
    "details": [
      {
        "shipment_ref_no": "32",
        "point_of_contact": {
          "empid": ""
        },
        "products": {
          "0": " Pizza"
        },"status": "2"
      },
      {
        "shipment_ref_no": "VAPL/EXP/46/14-15",
        "point_of_contact": {
          "empid": "60162000009888"
        },
        "products": {
          "0": "MAIZE/CORN STARCH"
        },
        "status": "5"
      }
    ]
  }
}

我必须访问每个键的值。

以下是我的代码

NSString* pendingResponse = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

NSData *jsonData = [pendingResponse dataUsingEncoding:NSUTF8StringEncoding];

NSDictionary *jsonDic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingAllowFragments error:nil];
NSArray *argsArray = [[NSArray alloc] initWithArray:[jsonDic objectForKey:@"details"]];
NSDictionary *argsDict = [[NSDictionary alloc] initWithDictionary:[argsArray objectAtIndex:0]];
NSLog(@"keys = %@", jsonDic[@"values"]);

这是解析整个字典的方式:

NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

    NSArray *details = [[dataDictionary objectForKey:@"value"] objectForKey:@"details"];

    for (NSDictionary *dic in details) {
        NSString *shipmentRefNo = dic[@"shipment_ref_no"];
        NSDictionary *pointOfContact = dic[@"point_of_contact"];
        NSString *empId = pointOfContact[@"empid"];

        NSDictionary *products = dic[@"products"];
        NSString *zero = products[@"0"];
        NSString *status = dic[@"status"];

    }
