// magic macros
#define N(x) [NSNumber numberWithInt: x]
#define B(x) [NSNumber numberWithBool: x]

NSMutableArray *array = [[NSMutableArray alloc] init];

// long way
[array addObject:[NSNumber numberWithBool:YES]];
[array addObject:[NSNumber numberWithInt:1]];

// short way (using macro)
[array addObject:B(YES)];
[array addObject:N(1)];
