Problem with parsing JSON result

Question

Hello,

I have a problem with parsing a JSON result. This is what I get from my HTTP request:

{"subscriptions": [
     {"id":"A", "title":"A title"},  
     {"id":"B", "title":"B title"},  
]}

And this is what I'm doing in my code:

// Getting the result<br>
NSString *str = [[NSString alloc] initWithData:receivedData encoding:NSASCIIStringEncoding];

// Creating the JSON parser<br>
SBJSON *parser = [[SBJSON alloc] init];

// Parse result in an object<br>
NSDictionary *result = [parser objectWithString:str];

So far everything works fine. I have one key/value pair in my result object which I think is the subscriptions object. But the problem is now: How can I access the inner objects of it like the id and title?

Thanks for help.

The JSON parser will create nested NSArray and NSDictionary objects for you. To get to the array use:

NSArray *array = [result objectForKey:@"subscriptions"];

Then access the objects in the array like so:

NSDictionary *arrayObject = [array objectForIndex:0];

And finally, to get one of the inner objects do:

NSString *stringObject = [arrayObject objectForKey:@"id"];
