Tengo una clase People que contiene varias partes de una persona. Me gustaría poder identificar qué tipo de persona es, así que pensé en intentar usar un typedef enum para esto, ya que lo he visto antes y parece ser la solución más limpia. Pero no estoy seguro de cómo declarar esto, luego convertirlo en una propiedad.

.h

typedef enum {
    kPersonTypeFaculty,
    kPersonTypeStaff,
    kPersonTypeSearch
} personType;

@interface Person : NSObject {
    NSString *nameFirst;
    NSString *nameLast;
    NSString *email;
    NSString *phone;
    NSString *room;
    NSString *status;
    NSString *building;
    NSString *department;
    NSString *imageURL;
    NSString *degree;
    NSString *position;
    NSString *bio;
    NSString *education;
}

@property (nonatomic, retain) NSString *nameFirst;
@property (nonatomic, retain) NSString *nameLast;
@property (nonatomic, retain) NSString *email;
@property (nonatomic, retain) NSString *phone;
@property (nonatomic, retain) NSString *room;
@property (nonatomic, retain) NSString *status;
@property (nonatomic, retain) NSString *building;
@property (nonatomic, retain) NSString *department;
@property (nonatomic, retain) NSString *imageURL;
@property (nonatomic, retain) NSString *degree;
@property (nonatomic, retain) NSString *position;
@property (nonatomic, retain) NSString *bio;
@property (nonatomic, retain) NSString *education;

@end

.metr

#import "Person.h"


@implementation Person

@synthesize nameFirst, nameLast, email, phone, room, status, building, department, imageURL, degree, position, bio, education;

- (void)dealloc {
    [nameFirst release];
    [nameLast release];
    [email release];
    [phone release];
    [room release];
    [status release];
    [building release];
    [department release];
    [imageURL release];
    [degree release];
    [position release];
    [bio release];
    [education release];
    [super dealloc];
}

@end

Quiero poder hacer algo como:

Person *person = [[[Person alloc] init] autorelease];
person.nameFirst = @"Steve";
person.nameLast = @"Johnson";
person.personType = kPersonTypeStaff;

¿Me estoy perdiendo una parte crucial de esta idea?
