How to parse the data in JSONKit with following format

Question

I have following data and i want to print the list of items with following structure.

Let me know how can i do that.

I can't get the data using the following syntax.

/* Data to Row Json from URL*/
NSString *MyRowJson = [NSString stringWithContentsOfURL:url
                                               encoding:NSUTF8StringEncoding error:nil]; 

/* Copy data to Items from MyRowJson*/
NSDictionary *items = [MyRowJson objectFromJSONStringWithParseOptions:true];

/*get the deals data*/
NSMutableArray *ResponseData = [items objectForKey:@"deals"];

/*Get the count and based on this loop through the objects.*/    
NSLog(@"deals data count is %d",[ResponseData count]);

Here i got exception while printing the count.

Following is the structure of my data.

{
    "meta": {
        "code": 200
    }, 
    "response": {
        "deals": [

Your are pasring the data correctly and you grab the deals from the top most node, but it is under the response node:

NSString *jsonData = [NSString stringWithContentsOfURL:url
                                               encoding:NSUTF8StringEncoding error:nil]; 
NSError *error = nil;
NSDictionary *items = [jsonData JSONObjectWithData:data options:0 error:&error];

if (!items) {
   NSLog(@"Could not parse json:%@", error);
   return;
} 
/*get the deals data*/
NSDictionary  *response = [items objectForKey:@"response"];
NSArray *dealsArray = [response objectForKey:@"deals"];

/*Get the count and based on this loop through the objects.*/    
NSLog(@"deals data count is %d",[dealsArray count]);

Also object returned fro the JSON are inmutable, thus you can't just assign them to mutable objects. You will need to use the copyMutable methode of the inmutable type to get the mutable type. Do keep in mind that copyMutable need to released in non ARC projects.
