Dismissing a Popover created by a segue on iOS 9

There are a lot of questions and answers on Stack Overflow about this but they are just valid for iOS 8 and before.

iOS 9 deprecated a lot of things and the answers on SO did not work anymore.

Said that, I am presenting a popover by performing a segue like this

[self performSegueWithIdentifier:@"myPopover" sender:self];

This segue is created between the current viewController and the viewController used by the popover. There is no button involved. The popover is anchored to a view.

The problem is that on prepareForSegue:identifier

[segue destinationViewController]

is a UIViewController and 

[[segue destinationViewController] popoverPresentationController]

is the new UIPopoverPresentationController and this object does not offer a dismiss api anymore.

Instead, we are supposed to use

[self dismissViewControllerAnimated:YES completion:nil];

to dismiss the popover but this has no effect for me.

My situation is this: I have a popover with a text field. I want to dismiss the popover if the user hides the keyboard.

So I did this:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];

and then

- (void)keyboardWillHide:(NSNotification *)notification {
  [self dismissViewControllerAnimated:YES completion:nil];
}

but this has no effect at all.

I have also tried to create an unwind segue inside the popover viewController and call that from the presenting view controller but that makes the app crash.

Just tried it and it all seems to work perfectly.

  • What is your view controller hierarchy (navigation controllers, etc.)?
  • Are you properly calling dismissViewControllerAnimated:completion: on the same view controller that presented the popover?
  • Make sure there isn't a mixup between child view controller and navigation controller.
  • You can also log the popover view controller's presentingViewController to check.
