Parsing Json Array of Arrays

Question

Hi everyone,

This is my first post on stackoverflow so please be patient :-)

I have an Json Array of Arrays:

 {
  "response_type": "ok",
  "total_results": 1,
  "page": 1,
  "total_pages": 1,
  "sets": [
    {
      "id": 2075184,
      "created": 1269989599,
      "term_count": 5,
      "has_images": false,
      "terms": [
        [
          "\u9031\u672b",
          "Weekend",
          ""
        ],
        [
          "\u65e5\u66dc\u65e5",
          "Sunday",
          ""
        ],
        [
          "\u571f\u66dc\u65e5",
          "Saturday",
          ""
        ],
        [
          "\u79c1",
          "I, myself",
          ""
        ],
        [
          "\u65e5\u672c\u8a9e",
          "Japanese",
          ""
        ]
      ]
    }
  ]
}

I am using this code in my project to get the "terms" into an NSDictionary:

  NSURL *url = [NSURL URLWithString:@"http://localhost/json"];

  NSString *jsonreturn = [[NSString alloc] initWithContentsOfURL:url];  
  NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding];
  NSError *error = nil;
  NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error];

  NSLog(@"dict1: %@", dict);
  if (dict)
  {
    rows = [dict objectForKey:@"sets"];
  }

  NSLog(@"Array: %@", rows);

However I am having trouble figuring out how to get the terms separated for example:

[
          "\u9031\u672b",
          "Weekend",
          ""
        ],

I would like an NSArray of all the Japanese: "\u9031\u672b"(that is japanese btw) and an NSArray of all the definitions Weekend (Or a NSDictionary). However I am not sure how to separate them. We can safely assume that all the Japanese is 0 and all the definitions are 1. Any help would be wonderful!

thank you,

Answer 1

Have you considered using the JSON Framework for Objective-C iPhone?

Answer 2

    [
    "\u9031\u672b",
    "Weekend",
    ""
    ],

I would like an NSArray of all the Japanese: "\u9031\u672b"(that is japanese btw) and an NSArray of all the definitions Weekend (Or a NSDictionary). However I am not sure how to separate them. We can safely assume that all the Japanese is 0 and all the definitions are 1.

So element 0 (and likewise element 1) may be a string or an array, and if it's not an array, you want to wrap it in an array?

Just do that, then. Get element 0, test whether it's an array, and wrap it in one if it isn't. Then, do the same for element 1.

You might consider making some changes on the server side, if you can: Serve up the data as a dictionary with keys chosen for clarity, rather than an array with magic indexes, and have any values that are zero-or-more or one-or-more always be arrays.
