Swift navigating between viewcontrollers

Im looking for a word, method or similar for this situation. Say that i'm for example have 3 viewcontrollers, a, b and c.

And then i'm navigating from a to b and finally from b to c. From c then I want to dismiss my viewcontrollers all the way back to a. How do i achive this programmatically?

Solution

  • If you're using a UINavigationController you can use popToRootViewController

    import UIKit

class AViewController: UIViewController {}
class BViewController: UIViewController {}
class CViewController: UIViewController {}

let a = AViewController()
let b = BViewController()
let c = CViewController()

let nav = UINavigationController(rootViewController: a)
nav.pushViewController(b, animated: true)
nav.pushViewController(c, animated: true)

// Option 1
nav.popToRootViewController(animated: true)

// Option 2
nav.popToViewController(a, animated: true)
