如何使用EKEvent？

Question

NSDictionary *d = (NSDictionary *) [arrGarden objectAtIndex:0]; 
    int intarrCount=0; 

    NSString *strDate =[NSString stringWithFormat:@"%@", [d valueForKey:@"open_date_for_calendar"]]; 

    NSArray *arrDateList =[strDate componentsSeparatedByString:@","]; 


    NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; 
    dateFormatter = [[NSDateFormatter alloc] init]; 
    [dateFormatter setDateFormat:@"MM/dd/yyyy"]; 
    [dateFormatter setTimeZone:[NSTimeZone localTimeZone]]; 



    for(int i=0;i<[arrDateList count];i++) 
    { 
     intarrCount++; 
     EKEventStore *eventDB = [[EKEventStore alloc] init]; 

     EKEvent *myEvent = [EKEvent eventWithEventStore:eventDB]; 

     NSString *trimmedString = [[arrDateList objectAtIndex:i] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; 
     // NSString *trimmedString = [NSString stringWithFormat:@"%@",[[arrDateList objectAtIndex:i] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; 

     myEvent.title  = [d valueForKey:@"garden_name"]; 
     myEvent.startDate = [dateFormatter dateFromString:trimmedString]; 
     //myEvent.endDate = [dateFormatter dateFromString:trimmedString]; 
     myEvent.endDate = [[NSDate alloc] initWithTimeInterval:0 sinceDate:myEvent.startDate]; 
     myEvent.allDay = YES; 

     [myEvent setCalendar:[eventDB defaultCalendarForNewEvents]]; 
     NSError *err; 
     [eventDB saveEvent:myEvent span:EKSpanThisEvent error:&err]; 
     //NSString *eID = myEvent.eventIdentifier; 


    if(intarrCount == [arrDateList count]) 
    { 
     if (err == noErr) { 
      UIAlertView *alert = [[UIAlertView alloc] 
            initWithTitle:@"Event Added to your calendar" 
            message:nil 
            delegate:nil 
            cancelButtonTitle:@"OK" 
            otherButtonTitles:nil]; 
      [alert show]; 
      [alert release]; 
     } 
    } 
    } 

上述我行的，我用代碼..

當我添加事件到日曆事件成功添加日曆，但10-15秒後，事件被自動刪除... 請幫我在哪裏我有錯誤的代碼行 謝謝....

此代碼用於添加事件。

-(IBAction)eventAddToiCal:(id)sender 
    { 

     if(txtTitle.text.length == 0) 
     { 
      UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Enter Data" message:@"Please enter data into fields" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil ]; 
      [alert show]; 
      [alert release]; 
     } 
     else 
     { 
      event = [EKEvent eventWithEventStore:eventStore]; 
      event.startDate = startDate; 
      event.title = txtTitle.text; 
      event.location = txtLocation.text; 
      event.endDate = endDate; 
      event.notes = txtvNote.text; 

      /// tejas (Save Event in default Calendar of iPhone) 
      // Try to save the event 

      [event setCalendar:[eventStore defaultCalendarForNewEvents]]; 
      NSError *error = nil; 
      [self.eventsList addObject:event]; 
      [eventStore saveEvent:event span:EKSpanThisEvent error:&error]; 
     } 
    }
