Question

Is there a way to use something like

if (carRecord.status == CarRecord.statusRepaired) {  // using a class constant
    // ...
}

such as in a car repair shop, the carRecord object’s state status is checked against the CarRecord class’s constant. In Objective-C, is there such a way?

Answer 1

Here is how would you define it in .h file :

typedef enum CarRecordStatus {
    CarRecordStatusBroken = 0,
    CarRecordStatusRepaired,
} CarRecordStatus;

@interface MyClassName : NSObject    
..interfacebody..
@end

Use it inside MyClassName or any other just import it that’s it.
