我是故事板中的5个控制器，我如何以编程方式弹回到“官方初始控制器”？

Question

I am 5 Controllers deep into a Storyboard, how do I programmatically and easily pop back to the Official Initial Controller?

Is there some one liner for this? What is the most elegant and simple solution?

Answer 1

1 - On your root VC, create an unwind method: something like:

- (IBAction)unwindToRoot:(UIStoryboardSegue*);

Then wire it up to "exit" in your storyboard. This is an unwind segue.

or 2 - In your fifth VC, pop back manually:

[self.navigationController popToRootViewControllerAnimated:YES]

Answer 2

Indeed, there is a one-liner:

[self.navigationController popToViewController:(UIViewController *)];

Of course you would replace (UIViewController *) with the view controller at the beginning of the nav stack.
