How to pass data to ViewController, using UIViewController

Question

How to pass data to ViewController using this code?

UIStoryboard *main = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

UIViewController *vc = [main instantiateViewControllerWithIdentifier:@"Catalog"];

[self presentViewController:vc animated:YES completion:nil];

I want to pass data in example to itemId, like here:

ViewController *vc = [[ViewController alloc] initWithNibName:nil bundle:nil];

vc.itemId = 0;

[[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:vc animated:YES completion:nil];

You already have the vc.itemId = 0; line. What is it that you don't understand? — Wain

@Wain I think he means "I want to initialise the presented view controller as if I had done the following...". — trojanfoe

Type cast your UIViewController if it's ViewController

ViewController *vc = (ViewController*)[main instantiateViewControllerWithIdentifier:@"Catalog"];
vc.itemId = 0;
[self presentViewController:vc animated:YES completion:nil];

This should also work for you.

ViewController *vc=[self.storyboard instantiateViewControllerWithIdentifier:@"Catalog"];
vc.itemId =0;
[self presentViewController:vc animated:YES completion:Nil];
