Difference between pushViewController and showViewController

Question

What\'s the difference between pushViewController and showViewController methods on UINavigationController?

Answer 1

You use this method to decouple the need to display a view controller from the process of actually presenting that view controller onscreen.

Using this method, a view controller does not need to know whether it is embedded inside a navigation controller or split-view controller. It calls the same method for both. The UISplitViewController and UINavigationController classes override this method and handle the presentation according to their design. For example, a navigation controller overrides this method and uses it to push vc onto its navigation stack.
