Responding to "cancel" or "Done" in EKEventEditViewController

Question

I'm using a EKEventEditViewController which I'm able to populate with the info I need. I'm granted access to the Calendars and everything. My problem is when I click "Cancel" nothing happens. And when I click "Done" I get an error saying that No calendar has been set, no date has been set and "The event does not belong to that event store".

I don't think that my didCompleteWithAction delegate method is being called.

My viewController conforms to:

@interface EventoViewController : UIViewController <EKEventEditViewDelegate>

When I try to set self as delegate I get the error:

sending EventoViewController *const__strong' to parameter of incompatible type 'id<UINavigationControllerDelegate>'

Original Code .h

#import <UIKit/UIKit.h>
#import <EventKit/EventKit.h>
#import <EventKitUI/EventKitUI.h>

@interface EventoViewController : UIViewController <EKEventEditViewDelegate>

@property (weak, nonatomic) IBOutlet UILabel *eventDetailTitleLabel;
@property (weak, nonatomic) IBOutlet UILabel *eventDetailDateLabel;
@property (weak, nonatomic) IBOutlet UILabel *eventDetailDescriptionLabel;


- (IBAction)closeModalView:(id)sender;
- (IBAction)addEventToNative:(id)sender;


@end

Original .m

#import "EventoViewController.h"



@implementation EventoViewController

@synthesize eventDetailTitleLabel, eventDetailDateLabel, eventDetailDescriptionLabel;

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
    // iOS 6 and later
    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {

        // perform the main thread here to avoid any delay. normally seems to be 10 to 15 sec delay.
        [self performSelectorOnMainThread: @selector(presentEventEditViewControllerWithEventStore:) withObject:eventStore waitUntilDone:NO];



        if (granted){
            NSLog(@"We are granted to access Calendars!");
            //---- codes here when user allow your app to access theirs' calendar.

        }
        else {
            //---- code for no permission
            NSLog(@"We have no permission to access calendars!");
        }
    }];
}
}

- (void)presentEventEditViewControllerWithEventStore:(EKEventStore*)eventStore {
EKEventEditViewController* eventEditVC = [[EKEventEditViewController alloc] init];
eventEditVC.eventStore = eventStore;

EKEvent* event = [EKEvent eventWithEventStore:eventStore];

You need to assign self in your view controller class to the editViewDelegate property on the controller - the EKEventEditViewController class is a subclass of UINavigationController so the inherited delegate property is for handling navigation events. Hope that helps.

- (void)presentEventEditViewControllerWithEventStore:(EKEventStore*)eventStore {
    EKEventEditViewController* eventEditVC = [[EKEventEditViewController alloc] init];
    eventEditVC.eventStore = eventStore;
    // Add this line:
    eventEditVC.editViewDelegate = self;
