First import the EventKitUI/EventKitUI.h, EventKit/EventKit.h frameworks in your header file. This is the code to add an event to Default iCal(iPhone calendar).

-(IBAction) addEvent:(id)sender 
  { 
              EKEventStore *eventStore = [[[EKEventStore alloc] init] autorelease]; 
               EKEvent *events = [EKEvent eventWithEventStore:eventStore];

               events.title = @"Title";
                events.notes = @"Description";
                events.location = @"Location";
                events.startDate = [NSDate date];
                events.endDate = [NSDate date];
                events.availability = EKEventAvailabilityFree; 

                [events setCalendar:[eventStore defaultCalendarForNewEvents]];
                NSError *err;
                [eventStore saveEvent:events span:EKSpanThisEvent error:&err];
                 NSLog(@"Error From iCal : %@", [err description]);
    }

Then use this code to view the saved event in EKEventEditViewController,

EKEventEditViewController *editViewController = [[EKEventEditViewController alloc] init];
        editViewController.editViewDelegate = self;
        editViewController.event = event3;
        editViewController.eventStore = eventStore1;
        [self presentModalViewController:editViewController animated:YES];

I have used these code and it is working for me. Thanks.

Do you implement the -eventEditViewController:didCompleteWithAction: method?

If not, do something like the following:

- (void)eventEditViewController:(EKEventEditViewController *)controller didCompleteWithAction:(EKEventEditViewAction)action {
    [self dismissModalViewControllerAnimated:YES];

    EKEventStore *eventStore = [[[EKEventStore alloc] init] autorelease];
    NSError *error = NULL;

    [eventStore saveEvent:controller.event span:EKSpanThisEvent error:&error];

    if (error != NULL)
        NSLog(@"%@",[error localizedDescription]);
}
