如何在不能返回LoginViewController的情况下从LoginViewController到HomeViewController执行segue？

I'm developing an iOS app in Objective-C with Xcode 6. After my user logs in, my app performs a show (push) segue to the HomeViewController. On the HomeViewController the user has the ability to navigate back to the LoginViewController. Is it possible to have a push segue from the LoginViewController to the HomeViewController without the ability to navigate back to the LoginViewController? Or is my only option a modal segue?I'm developing an iOS app in Objective-C with X
