Question

Does any know how to get around viewDidAppear not being hit when exiting from a UIModalTransitionStylePartialCurl segue?

- (IBAction)buttonSelector:(id)sender
{

    // creating object for title screen
    UIStoryboard *storySelection =[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

    // creating object for profile view
    selectorViewController = [storySelection instantiateViewControllerWithIdentifier:@"Verse Selector"];

    // setting the transition style
    selectorViewController.modalTransitionStyle = UIModalTransitionStylePartialCurl;

    // performing the segue
    [self presentViewController:selectorViewController animated:YES completion:nil];
}

-(void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    // testing for a return from segue
    if (selectorViewController != nil)
    {
        // getting the chosen values from the instance
        chosenBook = selectorViewController.chosenBook;

        // setting instance to nil for garbage collection
        selectorViewController = nil;
    }
}

Answer 1

EDIT

It looks like the best route is to implement a custom delegate protocol which notifies the presenting view controller that the presented view controller is being dismissed.

Answer 2

One way to do this would to be to set your initial view controller as a delegate to your modally presented view controller. Before presenting the view controller:

selectedViewController.delegate = self;
[self presentViewController:selectorViewController animated:YES completion:nil];

Then, in the modal view controller, in whichever method dismisses the modal presentation, directly call viewDidAppear: on the original view controller.

- (void)doneButtonPressed:(id)sender
{
    [self.delegate viewDidAppear:NO];
    [self.delegate dismissModalViewControllerAnimated:YES];
}
