    NSDate *originalDate = [formatter dateFromString:strOriginalDate];

    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    NSDateComponents *components = [calendar components:NSDayCalendarUnit
                                               fromDate:originalDate

You may use this function. It formats argument date as follows:

if date is tomorrow, today, yesterday, day before yesterday, it returns corresponding text

if date is less than a week ago, returns week day, day and month

all other dates formatted in medium style

NSString* dateFormatted(NSDate* datetime){
if(datetime==nil){return nil;}

NSDate *todayWithTime=[NSDate date];

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *todayComponents=[gregorian components: (NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) fromDate: todayWithTime];
NSDate *tomorrow=[[NSDate alloc] initWithTimeInterval:86399 sinceDate:[gregorian dateFromComponents: todayComponents]];

NSDateComponents * interval = [gregorian components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) fromDate:datetime toDate:tomorrow options:0];

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setLocale:CurrentLocale()];

NSString *result;
if((interval.year==0)&&(interval.month==0)){
    if(interval.day==-1){
        result=NSLocalizedString(@"Tomorrow", @"");
    }else if(interval.day==0){
        result=NSLocalizedString(@"Today", @"");
    }else if(interval.day==1){
        result=NSLocalizedString(@"Yesterday", @"");
    }else if(interval.day==2){
        result=NSLocalizedString(@"The Day Before Yesterday", @"");
    }else if(interval.day<7){
        [dateFormatter setDateFormat:@"EEEE, d MMMM"];
        result = [dateFormatter stringFromDate:datetime];
    }else{
        [dateFormatter setDateStyle:NSDateFormatterMediumStyle];
        result = [dateFormatter stringFromDate:datetime];
    }
}else{
    [dateFormatter setDateStyle:NSDateFormatterMediumStyle];
    result = [dateFormatter stringFromDate:datetime];
}
return result;
}

You can try the below code to get the date difference

-(void)getDateDiffrenceForBirthday:(NSString *)strOriginalDate  

{
    NSDate *originalDate = [formatter dateFromString:strOriginalDate];
    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    NSUInteger unitFlags = NSDayCalendarUnit;
    NSDateComponents *components = [gregorian components:unitFlags fromDate:originalDate toDate:[NSDate date] options:0];

    NSLog(@"Days To Go %d",[components day]+1);

}

Source.
