SetViewControllers

SetViewControllers is a method used in the UIKit framework of Apple's iOS operating system. It is primarily associated with the UINavigationController class, which is a subclass of UIViewController that manages a stack of view controllers. The method allows developers to set the view controllers that the navigation controller will manage.

The setViewControllers method takes two parameters: an array of UIViewController objects and a boolean value. The array represents the new stack of view controllers that the navigation controller should manage. The boolean value, known as animated, determines whether the transition between the current stack and the new stack should be animated.

When setViewControllers is called, the navigation controller replaces its current stack of view controllers with the new stack provided in the array. If the animated parameter is set to true, the transition between the old and new stacks is animated, providing a smooth visual transition for the user. If set to false, the transition is instantaneous.

This method is particularly useful in scenarios where the navigation stack needs to be reset or updated dynamically, such as when implementing a complex navigation flow or when responding to user actions that require a significant change in the navigation hierarchy. It allows developers to have fine-grained control over the navigation stack, ensuring that the app's navigation behavior aligns with the desired user experience.
