NSJSONSerialization for an object with an id attribute

Question

Answer 1

Yes, id is a reserved keyword (although, as Josh points out, you could use it as a variable name, he's quite right that's a bad idea), but it can still be used as a key in a NSDictionary. For example, if your JSON looks like:

{ "id" : "23432423", "name" : "Jason Boggess" }

You can then parse it as follows:

NSError *error = nil;
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
if (error) {
    NSLog(@"%s: JSONObjectWithData error: %@", __FUNCTION__, error);
    return;
}
NSString *identifier = dictionary[@"id"];
NSString *name = dictionary[@"name"];

Answer 2

If you passed

{
    id: 123,
    name: "Chris"
}

to NSJSONSerialization as an NSData object you would get an NSDictionary with two keys that are NSString's with the value @"id" and @"name", at that point you can take the value from the id key and pass it to an attribute on your Objective-C model that is named something other than id. An example being recordId
