C macro for creating handy static constants in obj-c. Is this a bad or good idea?

static_const.m

#define STATIC_CONST(name) static NSString * const name = @#name;

STATIC_CONST(LearningNavRestorationIdentifier)
STATIC_CONST(ProfileNavRestorationIdentifier)
STATIC_CONST(ReservationsNavRestorationIdentifier)

#undef STATIC_CONST

// Becomes:

static NSString * const LearningNavRestorationIdentifier = @"LearningNavRestorationIdentifier";
static NSString * const ProfileNavRestorationIdentifier = @"ProfileNavRestorationIdentifier";
static NSString * const ReservationsNavRestorationIdentifier = @"ReservationsNavRestorationIdentifier";
