iOS, Set delegate for scene without using segue

Question

I am trying to navigate to a scene without using a segue. The code I am using looks like this:

UIStoryboard * storyboard = [UIStoryboard storyboardWithName:storyboardName bundle:nil];
MyViewController * controller = (MyViewController *)[storyboard instantiateViewControllerWithIdentifier:viewControllerID];
[self presentViewController:controller animated:YES completion:nil];

My problem is setting the delegate for this scene. Usually I would do the following:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Check the segue identifier
    if ([[segue identifier] isEqualToString:@"showDetail"])
    {
        [[segue destinationViewController] setDelegate:self];
    }
}

But I do not want to use segues. Can anyone please tell me how I could set the delegate for the scene?

Thanks

Answer 1

UIStoryboard * storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
DetailViewController * controller = (DetailViewController *)[storyboard instantiateViewControllerWithIdentifier:@"DetailView"];
controller.delegate = self;
[self presentViewController:controller animated:YES completion:nil];

Answer 2

YOu can set the delegate for the scene you are loading.

Your "destinationViewController" will have a method "ViewWillAppear". There you can set the delegate to self.

Answer 3

as you already have a reference to the new controller you don't need to implement the prepareForSegue:sender: method, after the line:

MyViewController * controller = (MyViewController *)[storyboard instantiateViewControllerWithIdentifier:viewControllerID];

just add:

[controller setDelegate:self];
