Event Kit, A Glance

As my project needs to add Event to Calendar in iOS System, I have a chance to take Event Kit a glance. It's available from iOS4.0, and get full function in iOS6.0.

First Add EventKit.framework to your project. Then add a new Event like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

// First get the event store object     EKEventStore *eventStore = [[EKEventStore alloc] init];     // Then create a new event     EKEvent *event  = [EKEvent eventWithEventStore:eventStore];     // Set the start and end date     NSDate *startDate = [NSDate date];     NSDate *endDate  = [NSDate date];     // Set properties of the new event object     event.title     = @"Your Event Tittle Here";     event.startDate = startDate;     event.endDate   = endDate;     event.allDay    = NO;     event.location  = @"Your Event Location";     // Set event's alarm     EKAlarm *alarm = [EKAlarm alarmWithAbsoluteDate:[NSDate date]];     [event addAlarm:alarm];     // Set event's calendar to the default calendar     [event setCalendar:[eventStore defaultCalendarForNewEvents]];     // Create an NSError pointer & save the event     NSError *error;     [eventStore saveEvent:event span:EKSpanThisEvent error:&error];     // Here get eventIdentifier and stroe it for further use     // like remove event     //event.eventIdentifier;

Using the eventIdentifier string to delete the event like this:

1 2 3 4 5 6 7 8 9 10 11 12

if (eventIdentifier && [eventIdentifier length]>0)     {         // Get the event store object         EKEventStore *eventStore = [[EKEventStore alloc] init];         // Get event with eventIdentifier we get when the event is create.         EKEvent *event = [eventStore eventWithIdentifier:eventIdentifier];         if (event)         {             // Remove event             [eventStore removeEvent:event span:EKSpanThisEvent error:&error];         }     }

You can use EKEventEditViewController in EventKitUI.framework to add new event.

1 2 3 4 5 6 7 8

// Get the event store object     EKEventStore *eventStore = [[EKEventStore alloc] init];     // Create the EditViewController     EKEventEditViewController* controller =[[EKEventEditViewController alloc] init];     controller.eventStore = eventStore;     controller.editViewDelegate = self;     [self presentModalViewController: controller animated:YES];     controller = nil;
