iOS: Date Components to ignore the year

I wrote an app lets the user enter in a date on a date picker, and they will press a button to schedule a local notification 3 days before the date is approaching. The only issue is, how would I edit this code to not factor in the year that the user types in? Because they may type in something like 1980 for the year, which obviously has already passed.

I tried deleting [dateComps setYear:[dateComponents year]];, but that causes the notification to fire immediately. I also tried deleting both that and NSYearCalendarUnit from the date components, but the same thing happens. Any help is much appreciated! Here is my code:

- (IBAction)scheduleNotifButton:(id)sender {
    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];

    NSDate *pickerDate = [self.datePicker date];

    NSDateComponents *dateComponents = [calendar components:( NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit )
                                                   fromDate:pickerDate];
    NSDateComponents *timeComponents = [calendar components:( NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit )
                                                   fromDate:pickerDate];

    NSDateComponents *dateComps = [[NSDateComponents alloc] init];
    [dateComps setDay:[dateComponents day]];
    [dateComps setMonth:[dateComponents month]];
    [dateComps setYear:[dateComponents year]];
    [dateComps setHour:13];
    [dateComps setMinute:30];
    [dateComps setSecond:[timeComponents second]];
    NSDate *itemDate = [calendar dateFromComponents:dateComps];

    UILocalNotification *localNotif = [[UILocalNotification alloc] init];
    if (localNotif == nil)
        return;
    localNotif.fireDate = itemDate;
    localNotif.timeZone = [NSTimeZone defaultTimeZone];

    localNotif.alertBody = @"Event is in 3 days!";
    localNotif.alertAction = nil;

    localNotif.soundName = UILocalNotificationDefaultSoundName;
    localNotif.applicationIconBadgeNumber = 0;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

}

As requested:

What if you just ignore the year entered and substitute it with the current year?

you can just get the current year, and set it to your dateComps

NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [calendar components:NSYearCalendarUnit fromDate:[NSDate date]];
[dateComps setYear:[components year]];

EDIT:

NSDateComponents *dateComps = [[NSDateComponents alloc] init];
[dateComps setDay:[dateComponents day]];
[dateComps setMonth:[dateComponents month]];

NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [calendar components:NSYearCalendarUnit fromDate:[NSDate date]];
[dateComps setYear:[components year]];

[dateComps setHour:13];
[dateComps setMinute:30];
[dateComps setSecond:[timeComponents second]];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
