Question

I’m trying to trigger a storyboard segue as soon as viewDidLoad is called on a view controller. The segue has an identifier attached, and works fine when called from inside a method thats linked to a button or other control. But it doesn’t work inside of viewDidLoad. It just silently fails. Is there some rule about segue’s being ignored in viewDidLoad?

I’ve tried both this:

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

and this:

[self dismissViewControllerAnimated:YES completion:^() {
[self performSegueWithIdentifier:@"mySegue" sender:self];
}];

Neither work.

You can not dismiss a view controller that isn’t presented yet. didLoad has purely memory management functions, you can use it as (part of a) constructor.
What may work, is to start a segue in viewDidAppear, however I would suggest to start with the view you want at the first time.
