EKCalendar not added to iCal
- by Alex75
I have a strange behavior on my iPhone. I'm creating an application that uses calendar events (EventKit). The class that use is as follows:
the .h one
#import "GenericManager.h"
#import <EventKit/EventKit.h>
#define oneDay 60*60*24
#define oneHour 60*60
@protocol CalendarManagerDelegate;
@interface CalendarManager : GenericManager
/*
* metodo che aggiunge un evento ad un calendario di nome Name nel giorno onDate.
* L'evento da aggiungere viene recuperato tramite il dataSource che è quindi
* OBBLIGATORIO (!= nil).
*
* Restituisce YES solo se il delegate è conforme al protocollo CalendarManagerDataSource.
* NO altrimenti
*/
+ (BOOL) addEventForCalendarWithName:(NSString *) name fromDate:(NSDate *)fromDate toDate: (NSDate *) toDate withDelegate:(id<CalendarManagerDelegate>) delegate;
/*
* metodo che aggiunge un evento per giorno compreso tra fromDate e toDate ad un
* calendario di nome Name. L'evento da aggiungere viene recuperato tramite il dataSource
* che è quindi OBBLIGATORIO (!= nil).
*
* Restituisce YES solo se il delegate è conforme al protocollo CalendarManagerDataSource.
* NO altrimenti
*/
+ (BOOL) addEventsForCalendarWithName:(NSString *) name fromDate:(NSDate *)fromDate toDate: (NSDate *) toDate withDelegate:(id<CalendarManagerDelegate>) delegate;
@end
@protocol CalendarManagerDelegate <NSObject>
// viene inviato quando il calendario necessita informazioni sull' evento da aggiungere
- (void) calendarManagerDidCreateEvent:(EKEvent *) event;
@end
the .m one

In practice, on my iphone I get the log:
fetch an old-one = (null)
19/12/2012 11:33:09.520 AppCampeggioSingolo [730:8 b1b] create new calendar
19/12/2012 11:33:09.558 AppCampeggioSingolo [730:8 b1b] Saved calendar EKCalendar
every time I add an event, then I look and I can not find it on iCal calendar event he added. On the iPhone of a friend of mine, however, everything is working correctly. I doubt that the problem stems from the code, but just do not understand what it could be.
I searched all day yesterday and part of today on google but have not found anything yet.
Any help will be greatly appreciated
EDIT: I forgot the call wich is
[CalendarManager addEventForCalendarWithName: @"myCalendar" fromDate:fromDate toDate: toDate withDelegate:self];
in the delegate method simply set title and notes of the event like this
- (void) calendarManagerDidCreateEvent:(EKEvent *) event
{
event.title = @"the title";
event.notes = @"some notes";
}
