How do I get this value from NSMutableArray?

Question

this is a fairly simple question.

I am using a web service in my app, and the server returns a JSON string to communitcate with the app.

Here is an example response:

{
    repsonse =     {
        message = "Message";
        "response_id" = X;
    };
}

Using objective-c I want to be able to get what "response_id" is but I am unsure on how to do this.

Here is my code:

NSMutableArray *json = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:nil];
// Get json value
NSLog(@"%@", json);

if([json[@"response"][@"response_id"] isEqualToString:@"1"]){
    return YES;
}else{
    return NO;
}

Each time the isStringEqualTo method returns false.

Could somebody help me?

Thanks,

Peter

You have two problems:

1. json needs to be declared as an NSDictionary , not NSMutableArray since the JSON root is a dictionary, not an array. And you get back an immutable dictionary, not a mutable one.
2. The JSON has a key of "repsonse", not "response".
