The document outlines the process for iOS development, focusing on essential design and coding principles. It emphasizes the importance of minimal code and practical use of Cocoa framework components, including custom classes and view controller lifecycle methods. Additionally, it provides a step-by-step guide for implementing a settings page and an article list page using JSON data in a UITableViewController.

Want vs. need
No code is good code
Do not start from 0
Keep step small

12. Mission 1
Setting page with less code

13. Wireframe of setting page

14. Steps
• Embed in UINavigationController (two ways)
• UITableViewController with static cells (basic and customize style).
• Create show segue with control + drag from cell
• Connect views with IBOutlet and change its property value.
• Simple autolayout (pin view in center of viewController)
• Simple class SRAuthor to setup author page

15. Mission 2
Article list page with JSON file

16. Wireframe of article list page

17. Steps
• Read JSON file as dictionary (Break point and check out data)
• List article title with dynamic cells in UITableViewController
(Delegate pattern, reuse cell with id).
• Configure cell with article JSON data
• Pass params to another viewController with segueId
