标题: ios - JSON响应中NSDictionary内的对象数组- objective-c

我正在尝试从 NSDictionary 的 JSON 响应中获取对象列表，然后将其存储在 NSMutableArray 中，但它一直只给我一个数组中的对象，可以请您帮我提供示例代码，

这是 json 响应:

{
  "errorCd": "00",
  "desc": "Success",
  "ref": 83,
  "statusCode": "1",
  "extraData": [
    {
      "key": "bal",
      "value": "80"
    },
    {
      "key": "txs",
      "value": "[{\"id\":2268099999,\"amnt\":100.0,\"curr\":\"JOD\",\"sender\":\"SPCI\",\"receiver\":\"00962799999992\",\"date\":\"Feb 1, 2016 4:03:25 PM\",\"status\":1,\"type\":5,\"fees\":0.0,\"reference\":40},{\"id\":2357099999,\"amnt\":20.0,\"curr\":\"JOD\",\"sender\":\"00962799999992\",\"receiver\":\"SPCI\",\"date\":\"Feb 2, 2016 12:52:35 PM\",\"status\":1,\"type\":6,\"fees\":0.0,\"reference\":68}]"
    }
  ]
}

我正在尝试获取键 txs 的值中的列表。

这就是我想要做的:

-(NSDictionary *)getListOfExtraDataNSMutableArray *)extras{
    NSDictionary *array = [[NSDictionary alloc] init];
    for (NSDictionary *dictionary in extras) {
        if([[dictionary valueForKey"key"] isEqualToString"txs"])
            array = [dictionary objectForKey"value"];
    }
    if (array != nil && array.count > 0)
        return array;
    return nil;
}

Best Answer-推荐答案

JSON 数据无效，因为 value 在 "

中有一个对象

你应该像这样发送你的 JSON

{

  "errorCd": "00",
  "desc": "Success",
  "ref": 83,
  "statusCode": "1",
  "extraData": [
    {
      "key": "bal",
      "value": "80"
    },
    {
      "key": "txs",
      "value": [
        {
          "id": 2268099999,
          "amnt": 100.0,
          "curr": "JOD",
          "sender": "SPCI",
          "receiver": "00962799999992",
          "date": "Feb 1, 2016 4:03:25 PM",
          "status": 1,
          "type": 5,
          "fees": 0.0,
          "reference": 40
        },
        {
          "id": 2357099999,
          "amnt": 20.0,
          "curr": "JOD",
          "sender": "00962799999992",
          "receiver": "SPCI",
          "date": "Feb 2, 2016 12:52:35 PM",
          "status": 1,
          "type": 6,
          "fees": 0.0,
          "reference": 68
        }
      ]
    }
  ]
}
