在不同的导航中从一个视图 Controller 弹出到另一个视图 controller

Question

I am trying to pop a view controller VC1 from one navigation controller NC1 to another view controller VC2 in another navigation controller NC2.

I am using the VIPER architecture thus routing between different view controllers in different navigational hierarchies requires that I must switch to the root of the navigation controller I want to present.

So the issue here is that, after navigating to the view controller VC2 of the second navigation controller NC2, I want to go back to the first view controller VC1 in the first navigation controller NC1.

I have tried the following:

 self.navigationController?.popViewController(animated: true)

 navigationController?.dismiss(animated: true, completion: nil)

 view.window?.rootViewController?.dismiss(animated: true, completion: nil)

 self.navigationController?.popToRootViewController(animated: true)

but none of them worked for me. Any ideas?

Answer 1

Please Try this codes:

let viewControllers = self.navigationController?.viewControllers

for vc in viewControllers! {

   if vc is VC1 {
      self.navigationController?.popToViewController(vc as! VC1, animated: true)
   }
}
