Based on Apple Documentation, this has changed a bit as of iOS 6.0.

1) You should request access to the user's calendar via "requestAccessToEntityType:completion:" and execute the event handling inside of a block.

2) You need to commit your event now or pass the "commit" param to your save/remove call

Everything else stays the same...

Add the EventKit framework and #import to your code.

To add an event:

   EKEventStore *store = [[EKEventStore alloc] init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
    if (!granted) { return; }
    EKEvent *event = [EKEvent eventWithEventStore:store];
    event.title = @"Event Title";
    event.startDate = [NSDate date]; //today
    event.endDate = [event.startDate dateByAddingTimeInterval:60*60];  //set 1 hour meeting
    [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
}];

Remove the event:

    EKEventStore* store = [[EKEventStore alloc] init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
    if (!granted) { return; }
    EKEvent* eventToRemove = [store eventWithIdentifier:savedEventId];
    if (eventToRemove) {
        NSError* error = nil;
        [store removeEvent:eventToRemove span:EKSpanThisEvent commit:YES error:&error];
    }
}];

You need the EventKit framework. You can ask the EKEventStore for its calendars, and then use those calendars to create a predicate that lets you find events that match the criteria you're looking for. Or you can create a new EKEvent object and save it into the event store.
