You are getting the response and the only problem i see is you are not able to retrieve values correctly.

While fetching data from JSON remember that in which format you are getting the data i.e. either you are getting arrays or dictionary.

Seeing your response you are getting Array which in itself contains dictionary.

use the below code to fetch the values

NSArray *array = [responseObject valueForKey:@"Main"];

    for (NSDictionary *dict in array) {
        NSInteger ids = [[dict valueForKey:@"id"] integerValue];
        NSString *name = [dict valueForKey:@"name"];
        NSString *thumbnail = [dict valueForKey:@"thumbnail"];
        NSArray *arrImages = [dict valueForKey:@"images"];
        //You can use them accordingly

    }

Hope this helps you. Happy coding :)
