Question

does EKEventEditViewController not support being pushed to a NavController? See code & error attached.

I can present the EKEventEditViewController modally fine, BUT when I try to push via the nav controller I get the following error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'

Code is:

EKEventEditViewController *addController = [[[EKEventEditViewController alloc] initWithNibName:nil bundle:nil] autorelease];
addController.eventStore = self.eventStore;
addController.editViewDelegate = self;

[self.navigationController pushViewController:addController animated:TRUE];   // ERROR HERE

EKEventEditViewController is subclass of UINavigationController, so it can't be pushed to another UINavigationController.

EKEventEditViewController should be presented modally.

In case you're looking for some code to jumpstart an iPad-with-popover implementation:

EKEventStore *eventStore [[EKEventStore alloc] init];
EKEventEditViewController *eventController = [[EKEventEditViewController alloc] init];
eventController.editViewDelegate = self; 
eventController.eventStore = eventStore;

EKEvent *event  = [EKEvent eventWithEventStore: eventStore];
event.title     = @"New Event";
event.startDate = [[NSDate alloc] init];
event.endDate   = [[NSDate alloc] initWithTimeInterval: 60 * 60 sinceDate: event.startDate];
eventController.event = event;

/* You can add EKEventEditViewController directly to the popover -- this had me baffled for _hours_ */
popover = [[UIPopoverController alloc] initWithContentViewController: eventController];

You will also want to include this delegate method to do whatever you need to when the user completes or cancels event editing:

- (void) eventEditViewController: (EKEventEditViewController *)controller didCompleteWithAction: (EKEventEditViewAction)action 
{
    EKEvent *thisEvent = controller.event;

    switch (action) {
        case EKEventEditViewActionCanceled:
            NSLog(@"Canceled action");
            break;

        case EKEventEditViewActionSaved:
            NSLog(@"Saved action: %@", thisEvent.startDate);
            break;

        case EKEventEditViewActionDeleted:
            NSLog(@"Deleted action");
            break;

        default:
            break;
    }

    [popover dismissPopoverAnimated: YES];
}

Enjoy!

For future readers:

EKEventEditViewController is a UINavigationController so you can just say:

EKEventEditViewController *controller = [[EKEventEditViewController alloc] init];

// Set your properties here

[self.navigationController pushViewController:controller.viewControllers[0] animated:YES];

This works for me, but I don't know if you can do this for Apple.
