ios - AFNetworking 和 jSON

Question

我正在关注来自网络服务 API 的 json 响应。我想从 json 中提取产品数据。我也想使用 AFNetworking 来实现它。

 {"products": [
    {
      "product_id": "1170",
      "name": "zzzz®",
      "sort_order": 0,
      "brand": "zzzas",
      "product_category_id": "1090",
      "location_ids": [
        "1078"
      ],
      "icon_url": "http://zzzzz.com/media/2502/zzzz.png",
      "icon_date": "Wed, 07 Nov 2012 14:03:47 GMT",
      "thumbnail_url": "http://zzzz.com/media/2591/zzdfs.png",
      "thumbnail_date": "Wed, 07 Nov 2012 14:04:02 GMT"
    },
    {
      "product_id": "1126",
      "name": "ddddd®",
      "sort_order": 1,
      "brand": "dddsas",
      "product_category_id": "1110",
      "location_ids": [
        "1095"
      ],
      "icon_url": "http://zzzzz.com/media/2507/ddddd.png",
      "icon_date": "Wed, 07 Nov 2012 14:03:48 GMT",
      "thumbnail_url": "http://zzzzz.com/media/2596/sssds.png",
      "thumbnail_date": "Wed, 07 Nov 2012 14:04:05 GMT"
    }
]}

任何人都可以建议一种方法来做到这一点。我将如何完成这些事情。

Answer 1

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"link"]];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request 
    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
        NSDictionary *jsonDict = (NSDictionary *) JSON;
        NSArray *products = [jsonDict objectForKey:@"products"];
        [products enumerateObjectsUsingBlock:^(id obj,NSUInteger idx, BOOL *stop){
            NSString *productIconUrl = [obj objectForKey:@"icon_url"];
        }];

    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response,
        NSError *error, id JSON) {
            NSLog(@"Request Failure Because %@",[error userInfo]); 
    }
];

[operation start];
