How to Programmatically Create new Calendars on iPhone that will sync to iCal - iphone

Question

I'm looking for a way to create a new Calendar on the iphone device programatically. I have been looking at Event Kit and it clearly states how to create a new event in a calendar and there is also a convenient way of gathering all the calendars in code, What I can't find is how to create a new one that is saved to the device.
Any ideas'

Check this kal repository for creating programmatically iphone calendar same as iCal
Check this method for creating programmatically event:
-(void)initCalendar {
// An array of 1 dictionary object, containing START and END values.
NSMutableArray* pvDict = [[NSMutableArray alloc] initWithContentsOfURL:[NSURL URLWithString:PV_URL ]];
// Check if the private view event already exists in the default calendar.
// Then set the calendar button state.
// Get a entry point to the Calendar database.
self.store = [[EKEventStore alloc ] init ];
// Get an array of all the calendars.
NSArray *calendars = store.calendars;
// Get the default calendar, set by the user in preferences.
EKCalendar *defaultCal = store.defaultCalendarForNewEvents;
// Find out if this calendar is modifiable.
BOOL isDefaultCalModifiable = defaultCal.allowsContentModifications ;
// Create an event in the default calendar.
self.event = [ EKEvent eventWithEventStore:store ];
self.event.title = CHELSEA_SPACE ;
self.event.location = CHELSEA_ADDRESS ;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyy-MM-dd HH:mm:ss.S"];
NSString *startString = [[ pvDict objectAtIndex:0] objectForKey:#"starts" ];
NSDate *dateStart = [dateFormatter dateFromString:startString];
NSString *endString = [[ pvDict objectAtIndex:0] objectForKey:#"ends" ];
NSDate *dateEnd = [dateFormatter dateFromString:endString];
self.event.startDate = dateStart;
self.event.endDate = dateEnd;
self.event.calendar = defaultCal ;
// Alternative code to add 2.5 hours to start time.
// [[NSDate alloc] initWithTimeInterval:9000 sinceDate:event.startDate];
// Search for events which match this date/time start and end.
// Compare the matched events by event TITLE.
NSPredicate *predicate = [store predicateForEventsWithStartDate:event.startDate
endDate:event.endDate calendars:calendars];
NSArray *matchingEvents = [store eventsMatchingPredicate:predicate];
self.calendarButton.enabled = NO;
if( ! isDefaultCalModifiable ) {
// The default calendar is not modifiable
return ;
}
if ( [ matchingEvents count ] > 0 ) {
// There are already event(s) which match this date/time start and end.
// Check if this event is the PV
EKEvent *anEvent;
int j;
for ( j=0; j < [ matchingEvents count]; j++) {
anEvent = [ matchingEvents objectAtIndex:j ] ;
if([ CHELSEA_SPACE isEqualToString: anEvent.title ]) {
// PV event already exists in calendar.
return;
}
}
[ anEvent release ];
}
self.calendarButton.enabled = YES;
[ pvDict release ];
}
-(void)addEventToCalendar:(id)sender {
NSError *error;
BOOL saved = [self.store saveEvent:self.event span:EKSpanThisEvent error:&error];
NSLog(#"Saved calendar event = %#\n", (saved ? #"YES" : #"NO"));
self.calendarButton.enabled = NO;
}
