Any type of view controller can be placed on the STACK. When designing a navigation controller, you need to specify the root view, which is the first view that the user Sees. The root view controller is the first view controller that is pushed into the stack by a navigation controller. When the user views the next attempt, a new view controller is added to the stack, and the view it controls is displayed to the User. We can use the navigation buttons to manipulate layered applications to control the push-in or roll-out of Views.</span></span><span style="color: #008080;"><span style="color: #008080;"></span>
