How to dismiss the eventeditviewcontroller when I have allowed editing on eventviewcontroller? - ios

Question

So I present an EKEventViewController with a UINavigationController. From inside the EKEventViewController I am able to edit the event. It presents an EKEventEditViewController. Everything thing works great(cancel/done buttons) except when I delete the event inside the EKEventEditViewController I recieve this
attempt to dismiss modal view controller whose view does not currently appear. self = modalViewController =
Here is my code...
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[CalendarViewController connectExchange];
if (connectionEx == YES)
{
NSDate *dateRepresentingThisDay = [self.sortedDays objectAtIndex:indexPath.section];
NSArray *eventsOnThisDay = [self.sections objectForKey:dateRepresentingThisDay];
EKEventViewController *eventViewController = [[EKEventViewController alloc] init];
eventViewController.allowsEditing = YES;
eventViewController.delegate = self;
EKEvent *event = [eventsOnThisDay objectAtIndex:indexPath.row];
eventViewController.event = event;
UINavigationController *navBar = [[UINavigationController alloc]initWithRootViewController:eventViewController];
[self.navigationController presentViewController:navBar animated:YES completion:nil];
}
}
- (void)eventViewController:(EKEventViewController *)controller didCompleteWithAction:(EKEventViewAction)action
{
EKEvent *event = controller.event;
CalendarViewController * __weak weakSelf = self;
// Dismiss the modal view controller
[self dismissViewControllerAnimated:YES completion:^
{
if (action == EKEventViewActionDone)
{
dispatch_async(dispatch_get_main_queue(), ^{
NSError *err;
[self.eventStore saveEvent:event span:EKSpanThisEvent error:&err];
[self updateEvent:event];
});
}
if (action == EKEventViewActionDeleted)
{
dispatch_async(dispatch_get_main_queue(), ^{
[self deleteEvent:event];
NSError *error;
EKEvent *eventRemove = [self.eventStore eventWithIdentifier:event.eventIdentifier];
[self.eventStore removeEvent:eventRemove span:EKSpanThisEvent error:&error];
});
}
if (action == EKEventViewActionResponded)
{
dispatch_async(dispatch_get_main_queue(), ^{
});
}
weakSelf.eventsList = [self fetchEvents];
[weakSelf.tableView reloadData];
NSLog(#"Event Updated");
}];
}
How am I suppose to properly dismiss the ViewControllers after deleting the event via the EKEventEditViewController?

Answer 1

I solved my problem by subclassing EKEventViewController and setting up EKEventEditViewDelegate and EKEventViewDelegate.
Here is my changed didSelectRow(CalendarViewController.m),
EditViewController *eventViewController = [[EditViewController alloc] init];
eventViewController.allowsEditing = YES;
eventViewController.delegate = self;
EKEvent *event = [eventsOnThisDay objectAtIndex:indexPath.row];
eventViewController.event = event;
[self.navigationController pushViewController:eventViewController animated:YES];
self.editingEvent = eventViewController.event;
The EditViewController is my subclass of EKEventViewController.
In the subclass(EditViewController.m) I added my own edit button with a selector in viewDidLoad,
- (void)viewDidLoad
{
[super viewDidLoad];
UIBarButtonItem *editItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self.delegate action:#selector(editCalEvent)];
self.navigationItem.rightBarButtonItem = editItem;
}
Now back in CalendarViewController.m after adding the EKEventEditViewDelegate and EKEventViewDelegate to the #interface I added new methods
- (void)editCalEvent
{
EKEventEditViewController *editController = [[EKEventEditViewController alloc] init];
editController.event = self.editingEvent;
editController.eventStore = self.eventStore;
editController.editViewDelegate = self;
[self presentViewController:editController animated:YES completion:nil];
}
- (void)eventEditViewController:(EKEventEditViewController *)controller didCompleteWithAction (EKEventEditViewAction)action
{
EKEvent *thisEvent = controller.event;
[self dismissViewControllerAnimated:NO completion:^
{
switch (action)
{
{case EKEventEditViewActionCanceled:
//NSLog(#"Canceled action");
break;}
{case EKEventEditViewActionSaved:
[self.eventStore saveEvent:thisEvent span:EKSpanThisEvent error:nil];
[self updateEvent:thisEvent];
break;}
{case EKEventEditViewActionDeleted:
[self deleteEvent:thisEvent];
NSError *error;
EKEvent *eventRemove = [self.eventStore eventWithIdentifier:thisEvent.eventIdentifier];
[self.eventStore removeEvent:eventRemove span:EKSpanThisEvent error:&error];
//NSLog(#"Deleted action");
break;}
{default:
break;}
}
}];
}
- (void)eventViewController:(EKEventViewController *)controller didCompleteWithAction:(EKEventViewAction)action
{
}

Use the editViewDelegate instead of delegate.
