NSInteger is a type definition that describes an integer - but it is NOT equivalent to int on 64-bit platforms.

NSInteger is defined as int when building a 32-bit app and as long for 64-bit apps.

NSNumber is a class that helps you to store numeric types as object. It has methods to convert between different types and methods to retrieve a string representation of your numeric value.
If you use a variable day of type NSNumber* the way you did in your example, you are not modifying the value of day but its memory address.

NSUserDefaults -  need to call the synchronize every time you saved the data
it isn’t gauranteed it’ll be saved immediately.  sometimes it’ll wait XX seconds to do a synchronize on its own but by then the app could crash or the user could close the app

So there is tricky thing (it will happen sometimes)

/*
* When set a storyboardID in a viewcontroller, and you want to show the navigation item
* you need to init NavigationController with rootviewcontoller
*/
UIViewControllers *niceVC = [shop instantiateViewControllerWithIdentifier:@"nice"];
UINavigationController *niceNav = [[UINavigationController alloc] initWithRootViewController:nice];
