     NSString *urlString   = [NSString stringWithFormat:@"%@",homePagesNews];
 // The Openweathermap JSON responder
        NSURL *url            = [[NSURL alloc]initWithString:urlString];
        NSURLRequest *request = [NSURLRequest requestWithURL:url];
        NSURLResponse *response;
        NSData *GETReply      = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];

I want to get this value title,datetime,main_url . I check bellow mention link .

Thanks in advance

Try this way `NSLog(@"%@",[[res objectAtIndex:0] objectForKey:@"item_id"]);` — Dharmesh Dhorajiya, Oct 15 '15 at 07:16
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, Oct 15 '15 at 07:19

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"]);
