In the second part of the tutorial on creating UI elements programmatically using PureLayout, the author focuses on explaining how to incorporate essential UI components like UINavigationController, UITableView, and self-sizing UITableViewCell into a mobile application without using Storyboards or NIBs. The tutorial provides a comprehensive walkthrough on setting up a UINavigationController to facilitate navigation within the app, including handling the navigation bar's translucency. It emphasizes refactoring the ViewController by moving UI elements to a separate UIView subclass, adhering to the Model-View-Controller (MVC) architectural pattern to streamline code management. The tutorial also covers the integration of UITableView for displaying contact information, detailing the implementation of UITableViewDataSource and UITableViewDelegate protocols, and the creation of UITableViewCells, including self-sizing cells to accommodate varying content sizes. Through these steps, the tutorial highlights the benefits of building a UI programmatically, such as improved code maintainability and flexibility, while encouraging readers to explore Apple's official documentation for a deeper understanding of UIKit components.
