Add event to iPhone / iPad iCal

[bgp1]

Hello,

I have an application I am developing that pulls events from an RSS feed and then displays events to the user. I want to add the ability for the user to add the event they are looking at to the calendar on the iPhone but I have been unsuccessful in finding sample code or an example that does this. Does anyone have any sample code or anything that can help me accomplish this?

I am still just learning Cocoa (been at it for about 4 months) but I am very skilled in other C-based languages.


Thank you very much in advance!

You can only access the calendar as of iOS 4.0, see here: Event Kit Framework Reference

Thanks for the reply! Coding to iOS 4 standards shouldn't be an issue. Here's a copy of the code I have in my button on my interface. Would this work? I realized there isn't a way to test this on the simulator because the iCal doesn't exist there. I'd have to test it on the device...which is a hassle.

- (IBAction) addEvent {
	NSLog(@"button clicked");
	EKEventStore *eventStore = [[EKEventStore alloc] init];
	
    EKEvent *eventToAdd  = [EKEvent eventWithEventStore:eventStore];
    eventToAdd.title     = event.title;
	
    eventToAdd.startDate = [[NSDate alloc] init];
    eventToAdd.endDate   = [[NSDate alloc] initWithTimeInterval:600 sinceDate:eventToAdd.startDate];
	
    [eventToAdd setCalendar:[eventStore defaultCalendarForNewEvents]];
    NSError *err;
    [eventStore saveEvent:eventToAdd span:EKSpanThisEvent error:&err];
}

I can't test that right now... however I'd be tempted to use:

eventToAdd.startDate = [NSDate date];  // Set the start date to the current date/time.
eventToAdd.endDate = [NSDate dateWithTimeInterval:600.0f sinceDate:[eventToAdd startDate]];

rather than:

eventToAdd.startDate = [[NSDate alloc] init];
eventToAdd.endDate   = [[NSDate alloc] initWithTimeInterval:600 sinceDate:eventToAdd.startDate];

Your solution will cause a memory leak for both startDate and endDate as you've not released either NSDate objects or put them on the autorelease pool.

Thanks, I'll make those changes.
