For nested keys like that you can use a keyPath. A keyPath is just a series of keys joined with dots. You can use them to retrieve nested values from objects that support Key-Value Coding - including NSDictionary objects like yours. So in your case this should work:

For more detail on Key-Value Coding, see Apple's Key-Value Coding Programming Guide.
