Help with removing event from calendar

Question

Hello everyone I'm adding a simple feature in my xcode ios app that has a UISwitch. When the UISwitch is on an event is created (this part works fine). But when I turn the UISwitch off I cannot find a way to remove the event. If I use code in the second if statement to remove the event, the event identifier is undeclared because it is in a separate if statement. Can someone please tell me what code I need to remove the event.
Code:
- (IBAction)switchon:(id)sender {
    if (switchoutlet.on) {
        EKEventStore *store = [[EKEventStore alloc] init];
        [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
            if (!granted) { return; }
            EKEvent *event = [EKEvent eventWithEventStore:store];
            event.title = @"Event A";
            event.startDate = [NSDate dateWithTimeIntervalSince1970:1406948400]; //today
            event.endDate = [event.startDate dateByAddingTimeInterval:60*60];  //set 1 hour meeting
            EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:-60*10];
            event.alarms = [NSArray arrayWithObject:alarm];
            [event setCalendar:[store defaultCalendarForNewEvents]];
            NSError *err = nil;
            [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
            NSString *savedEventId = event.eventIdentifier;  //this is so you can access this event later
    if (!switchoutlet.on) {
        //remove event

Once something is on the Internet, it remains so.  That is why people (mainly children) are always advised not to post anything that they may come to regret in a few years time when you are looking for jobs and your potential employer does a background search on you.
