Deleting an EKEvent from device's calendar usi

问题:

I am creating EKEvent, saving it and saving its identifier as well. I wanna access this identifier and delete the specific Event. I am able to retrieve the proper Identifier from database. However, the Event isn't getting deleted from my Device's calendar. My code to delete the event : `NSError* err;

    EKEvent *myEvent = [EKEvent eventWithEventStore:homeobj.eventDB];

    myEvent = [homeobj.eventDB eventWithIdentifier:[dbObj selectEventIdentifier:mypass]];

    [homeobj.eventDB removeEvent:myEvent span:EKSpanThisEvent commit:YES error:&err];

`

For deleting use this code

-(void)removeMeWithIndex:(int)index
{
    EKEvent* eventToRemove = [eventStore eventWithIdentifier:[arrayofEventId objectAtIndex:index]];

    if (eventToRemove != nil) {
        NSError* error = nil;
        [eventStore removeEvent:eventToRemove span:EKSpanThisEvent error:&error];
    }
}

-(IBAction)remove
{
  [self removeMeWithIndex:0];
}

I have updated my code to check if id exists or not as

-(void)removeMeWithIndex:(int)index
{
    NSLog(@"id is %@",[[NSUserDefaults standardUserDefaults] valueForKey:@"id"]);
    EKEvent* eventToRemove = [eventStore eventWithIdentifier:[[NSUserDefaults standardUserDefaults] valueForKey:@"id"]];

    if (eventToRemove != nil) {
        NSError* error = nil;
        [eventStore removeEvent:eventToRemove span:EKSpanThisEvent error:&error];
    }
}

output after deletion is ...
