• What kind of change does this pull request introduce? feature
  The ability to have the action that generated the dismiss of the alert in the delegate protocol

[vsanthanam]

I think there needs to be some discussion around this feature.

1. does the delegate instance method -alertController:didSelectAction: not already provide this functionality?
2. doesn't this kind of invalidate the point of the will & did appear & disappear delegate methods? There are other ways the view controller can disappear, without an action being selected. These delegate methods exist to forward additional functionality of the usual view controller lifecycle methods to the alert view controller, because the user doesn't have access to the inner workings of VSAlertController without subclassing. Basically, if you were creating this controller, you append additional functionality to -viewWillAppear:animated:. -viewDidAppear:animated:, etc.

Here is an example of an alert controller being dismissed without an action being tapped:

- (void)showAlert {

   self.alert = /* instantiate vsialertcontroller */

}

- (void)hideAlert {

    // alert controller dismissed without user ever interacting with an action
    [self.alert dismissViewControllerAnimated:YES completion:nil];

}
