In using a Navigation Controllers in iOS, you benefit from different segue controllers and methods for navigating from one view controller to another one. Navigation controller uses the show methods for transitions. In doing so, a view pushes the destination view controller onto the navigation stack. As a result, the source view controller gets pushed out of the way (destination slides over top from right to left), providing a back button for navigating back to the source – on all devices.
Summary Navigation Controllers
Navigation controllers are a fundamental transition process for most iOS apps. For using Navigation Controllers, we can either start with a new Navigation Controller and add our view controller as the “Root View Controller” or embed our existing view controllers within a Navigation Controller.
