Solo quiero una matriz que contenga todos los lunes del año en forma de NSDate pero de forma rápida. Estoy usando el siguiente código en el objetivo -c pero no sé cómo usarlo rápidamente.

 NSDate *pickerDate = [NSDate date];
    NSLog(@"pickerDate: %@", pickerDate);

    NSDateComponents *dateComponents;
    NSCalendar *calendar = [NSCalendar currentCalendar];

    dateComponents = [calendar components:NSWeekdayCalendarUnit fromDate:pickerDate];
    NSInteger firstMondayOrdinal = 9 - [dateComponents weekday];
    dateComponents = [[NSDateComponents alloc] init];
    [dateComponents setDay:firstMondayOrdinal];
    NSDate *firstMondayDate = [calendar dateByAddingComponents:dateComponents toDate:pickerDate options:0];

    dateComponents = [[NSDateComponents alloc] init];
    [dateComponents setWeek:1];

    for (int i=0; i<64; i++) {
        [dateComponents setWeek:i];
        NSDate *mondayDate = [calendar dateByAddingComponents:dateComponents toDate:firstMondayDate options:0];
        NSLog(@"week#: %i, mondayDate: %@", i, mondayDate);
    }
