If I want to retrieve EKEvent
from EKEventStore
with eventWithIdentifier
method for previously saved event but I always get null.
This is the code for adding event:
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *newEvent = [EKEvent eventWithEventStore:eventStore];
newEvent.title = @"Test";
newEvent.availability = EKEventAvailabilityFree;
newEvent.startDate = startDate;
newEvent.endDate = endDate;
[newEvent addAlarm:[EKAlarm alarmWithRelativeOffset:-15*60]];
newEvent.calendar = [eventStore defaultCalendarForNewEvents];
NSError *err;
BOOL success = [eventStore saveEvent:newEvent span:EKSpanThisEvent commit:YES error:&err];
if (success) {
if ([newEvent respondsToSelector:@selector(calendarItemIdentifier)]) {
[[NSUserDefaults standardUserDefaults] setObject:newEvent.calendarItemIdentifier forKey:self.showId];
NSLog(@"Event ID: %@",newEvent.calendarItemIdentifier);
}
else {
[[NSUserDefaults standardUserDefaults] setObject:newEvent.UUID forKey:self.showId];
NSLog(@"Event ID: %@",newEvent.UUID);
}
}
And code for removing event:
EKEventStore *eventStore = [[EKEventStore alloc] init];
NSError *err;
BOOL success = YES;
NSLog(@"Event ID: %@",[[NSUserDefaults standardUserDefaults] objectForKey:self.showId]);
EKEvent *existingEvent = [eventStore eventWithIdentifier:[[NSUserDefaults standardUserDefaults] objectForKey:self.showId]];
NSLog(@"Existing event: %@",existingEvent);
if (existingEvent != nil) {
success = [eventStore removeEvent:existingEvent span:EKSpanThisEvent error:&err];
}
if (success) {
[[NSUserDefaults standardUserDefaults] removeObjectForKey:self.showId];
}
Why I cannot remove previously added event from calendar with the same event id ?
This code was tested on iOS 5 (iPad 1) and iOS 6 (new iPad)...
I am using newEvent.eventIdentifier
instead of newEvent.calendarItemIdentifier
and so far, using [store eventWithIdentifier:_project.event_identifier]
, I can retrieve, delete and edit an existing event. you should try.
