iOS doing a pushViewController and don't pop

Question

I'm using pushViewController from my home view to go to the logoutView. After logout, I'm using a performSegue to redirect to the loginView.

Can it be a problem if I didn't use popViewController? (In term of stack or something like that).

2)

This is like that

(1) LoginViewController --> Prepare for segue --> HomeViewController --> PushViewController --> LogoutViewController

So from logoutViewController, what can I do go to back safely in LoginViewController ?

Edit : I did it. Thanks

I would highly, strongly recommend that you NOT do that. I am almost certain that you will pop another log-in controller onto the view controller stack. You will then have 4 view controllers in the stack when you only want one. Please look at this post on unwind segues or use popViewController.
