Deleting an event from iPhone's calendar

Question

I am trying to delete an event from the Calendar on user request. This is what I've come up with:

// Deleting Event
    EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
event.title     = appDelegate.title1;
event.startDate = appDelegate.recAddDate;
event.endDate   = appDelegate.currentDateName;
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore removeEvent:event span:EKSpanThisEvent error:&err];

Below is the function I'm calling to remove the event from the event array. Items array is used to fetch events from iPhone calendar

- (BOOL)removeEvent:(EKEvent *)event span:(EKSpan)span error:(NSError **)error{
    VoiceRecorderAppDelegate *appDelegate = (VoiceRecorderAppDelegate *)[[UIApplication sharedApplication] delegate];
    [items removeObjectAtIndex:appDelegate.objectindexpath];
}

Answer 1

Firstly, save the eventId for the event while adding/saving events to the calendar.

[eventStore saveEvent:event span:EKSpanThisEvent error:&err]; 
NSString* str = [[NSString alloc] initWithFormat:@"%@", event.eventIdentifier];
[arrayofEventId addObject:str];

and then identify the event you want to remove ande then remove that event.

EKEventStore* store = [[EKEventStore alloc] init];
EKEvent* eventToRemove = [store eventWithIdentifier:[arrayofEventId objectAtIndex:i]];
 if (eventToRemove != nil) {  
   NSError* error = nil;
  [store removeEvent:eventToRemove span:EKSpanThisEvent error:&error];
 } 

Also don't forget to remove that event from arrayofEventId as well.
