NSMutableString *postStr = [NSMutableString stringWithString:kURL];
[postStr appendString:[NSString stringWithFormat:#"?tag=%#&id=%#",kCategoryFilter,kPrecious]];
[postStr setString:[postStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:postStr]];
NSLog(#"%#",postStr);
[request setHTTPMethod:#"POST"];
_connection = [[NSURLConnection alloc]initWithRequest:request delegate:self startImmediately:YES];
NSURL *url = [NSURL URLWithString:postStr];
NSData *data = [NSData dataWithContentsOfURL:url];
pJson = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
NSLog(#"%#",pJson);
NSMutableArray *arr = [pJson objectForKey:#"Response"];
NSLog(#"%lu",(unsigned long)arr.count);
NSMutableDictionary *dict2 =[[NSMutableDictionary alloc]init];// [arr objectAtIndex:NSIndexPath.row];
[dict2 setObject:arr forKey:#"dictionary1"];
dict2 = [arr objectAtIndex:0];
NSArray *arr1 =[dict2 objectForKey:#"0"];
NSLog(#"%lu",(unsigned long)arr1.count);
NSUInteger y;
for (int i=0;i<arr.count;i++) {
NSString *ring_data = [[arr objectAtIndex:i]objectForKey:#"menuname"];
NSString *id_data = [[arr objectAtIndex:i]objectForKey:#"menuid"];
NSLog(#"AUTHOR: %#",ring_data);
NSLog(#"%#",id_data);
dictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
ring_data,#"menuname",id_data,#"menuId",nil];
[myObject addObject:dictionary];
NSMutableArray *arr1 = [dict2 objectForKey:#"0"];
NSLog(#"%lu",(unsigned long)arr1.count);
y = arr.count;
for (NSUInteger i=0;i<arr1.count;i++) {
NSArray *count = [[[arr1 objectAtIndex:i] objectForKey:arr]valueForKey:#"catname"];
NSString *myCount = [NSString stringWithFormat:#"%lu",(unsigned long)[count count]];
NSString *ring_data = [[arr1 objectAtIndex:i]objectForKey:#"catname"];
NSLog(#"AUTHOR: %#",ring_data);
// NSLog(#"%#",catname_data);
dictionary1 = [NSMutableDictionary dictionaryWithObjectsAndKeys:
ring_data,#"catname",
nil];
[myObject1 addObject:dictionary1];
}
}

I tried some coding for you.Follow that code and customize where you want to add to array and where to set dictionary.
NSDictionary *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];
NSArray *array=[jsonArray objectForKey:#"Response"];
for (int i=0;i<[array count];i++)
{
NSMutableDictionary *dict = [array objectAtIndex:i];
NSMutableArray *arrayDictValue = [dict valueForKey:[NSString stringWithFormat:#"%d",0]];
NSString *strMenuName = [NSString stringWithFormat:#"%#",[arrayDictValue valueForKey:#"menuname"]];
NSString *strMenuID = [NSString stringWithFormat:#"%#",[arrayDictValue valueForKey:#"menuid"]];
NSLog(#"The strMenuName is-%#",strMenuName);
NSLog(#"The strMenuID is-%#",strMenuID);
for (int j=0; j<[arrayDictValue count]; i++)
{
NSMutableDictionary *dictInside = [arrayDictValue objectAtIndex:j];
NSArray *arrayInsideDict = [dictInside valueForKey:#"0"];
for (int k =0; k<[arrayInsideDict count]; i++)
{
NSString *strCatName = [NSString stringWithFormat:#"%#",[[arrayInsideDict objectAtIndex:k ]valueForKey:#"catname"]];
NSString *strCatID = [NSString stringWithFormat:#"%#",[[arrayInsideDict objectAtIndex:k ]valueForKey:#"catid"]];
NSLog(#"The strCateName is-%#",strCatName);
NSLog(#"The strCatID is-%#",strCatID);
NSMutableDictionary *dictInArray = [[arrayInsideDict objectAtIndex:0] valueForKey:#"0"];
NSString *strSCatName = [NSString stringWithFormat:#"%#",[dictInArray valueForKey:#"scatname"]];
NSString *strSCatID = [NSString stringWithFormat:#"%#",[dictInArray valueForKey:#"scatid"]];
NSLog(#"the strSCatName is - %#",strSCatName);
NSLog(#"the strSCatID is - %#",strSCatID);
}
}
}
