        NSURLRequest *request = [NSURLRequest requestWithURL:url];
        NSURLResponse *response;

Try this way NSLog(@"%@",[[res objectAtIndex:0] objectForKey:@"item_id"]); — Dharmesh Dhorajiya

It is already an array... although your output must have been enclosed between two square brackets []. Is it exactly what you see in your debug console using NSLog? — sargeras

Try this code to get value

NSMutableArray *res     = [NSJSONSerialization JSONObjectWithData:GETReply options:NSJSONReadingMutableLeaves|| NSJSONReadingMutableContainers error:nil];
NSLog(@"%@",res);
// get item id
NSLog(@"item-id :%@",[[res objectAtIndex:0] objectForKey:@"item_id"]);
NSLog(@"datetime %@",[[res objectAtIndex:0] objectForKey:@"datetime"]);
NSLog(@"main_url %@",[[res objectAtIndex:0] objectForKey:@"main_url"]);

or get all value from response

for (int i=0; i< res.count; i++){
    NSLog(@"item-id :%@",[[res objectAtIndex:i] objectForKey:@"item_id"]);
    NSLog(@"datetime %@",[[res objectAtIndex:i] objectForKey:@"datetime"]);
    NSLog(@"main_url %@",[[res objectAtIndex:i] objectForKey:@"main_url"]);
}

Your response is collection of dictionary values, so you need to store your response in NSArray object like below :

    NSArray *res     = [NSJSONSerialization JSONObjectWithData:GETReply options:NSJSONReadingMutableLeaves|| NSJSONReadingMutableContainers error:nil];

To fetch attributes, use below code:

    NSDictionary * dict = [res objectAtIndex:0];
    NSLog(@"title = %@", [dict objectForKey:@"title"]);
