If you just want to save two NSStrings, you should use a simpler storage method, like NSUserDefaults, instead of Core Data, which is to be used for storing larger quantities of data. You can easily save an object to NSUserDefaults by using this code:

[[NSUserDefaults standardUserDefaults] setObject:someString forKey:@"someKey"];

Then you can retrieve the saved object like this:

NSString *someString = [[NSUserDefaults standardUserDefaults] objectForKey:@"someKey"];
