Help parsing a nested JSON object

Question

I have the following JSON:

{
    \"meta\": {
        \"code\": 200
    }, 
    \"response\": {
        \"deals\": [
            {
                   


        

Answer 1

You could try changing your code to something like this:

NSDictionary *primaryLocation =  [[[deal valueForKey:@"business"] valueForKey:@"locations"] objectAtIndex:0];
NSLog(@"Address: %@", [primaryLocation valueForKey:@"address"]);
NSLog(@"City: %@", [primaryLocation valueForKey:@"locality"]);
NSLog(@"Phone: %@", [primaryLocation valueForKey:@"phone"]);

Answer 2

[[deal valueForKey:@"business"] valueForKey:@"locations"] returns an array. Calling -valueForKey: on an NSArray executes valueForKey: for every object in the array and returns an array of the results (see the NSArray documentation for this). So that's what you get, an array of the corresponding values.

Answer 3

From the JSON you provided, locations is an array (that's what the square brackets mean), so the values that are returned from valueForKey: are contained in NSArray instances (hence the parentheses).

You could use objectAtIndex: before the last call to valueForKey: to obtain just the value you're looking for.

By the way, you can also use valueForKeyPath: to simplify accessing nested values, for example

[deal valueForKeyPath:@"business.name"];
