how to parse json in iOS

Question

this is the json string that i am receiving from the API:

"incentives_and_benefits" = "{\"food\":{\"0\":\"\"},\"commission\":{\"0\":\"\"},\"uniform\":{\"0\":\"\"},\"transport\":{\"0\":\"\"},\"extras\":{\"0\":\"\"}}";

and i assigned it to dictionary. Now I need to get the values inside the dictionary. I tried using the solution given here: How to get values from dict

Heres what I have so far:

    NSString *strIncentives = [[self.jobDetailDict objectForKey:@"sub_slots"] objectForKey:@"incentives_and_benefits"];
    NSData *jsonData = [strIncentives dataUsingEncoding:NSUTF8StringEncoding];

    NSError *e;
    NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:jsonData options:nil error:&e];
    NSLog(@"DICT: %@", dict);

    NSString *food = [dict objectForKey:@"food"];
    NSLog(@"DICT: %@", food);
    NSString *commission = [dict objectForKey:@"commission"];
    NSLog(@"DICT: %@", commission);
    NSString *uniform = [dict objectForKey:@"uniform"];
    NSLog(@"DICT: %@", uniform);
    NSString *transport = [dict objectForKey:@"transport"];
    NSLog(@"DICT: %@", transport);
    NSString *extras = [dict objectForKey:@"extras"];
    NSLog(@"DICT: %@", extras);

Now I need to check whether food's value is 0 or 1..When Food's value is 1 then i need to get Hello string and display it. (this is just an example) food: {"1":"Hello"}

    if([food isEqualToString:@""])
    {
        //the string will be placed here
        NSLog(@"FOOD Available")
    }

when i reach the if statement i get an error:

[__NSCFDictionary isEqualToString:]: unrecognized selector sent to instance

How will i be able to resolve this? please help and thank you in advance.

Go to json.org and learn the JSON syntax. It only takes 5-10 minutes to learn. — Hot Licks, Feb 11 '15 at 03:12
