Hour 13. Advanced Storyboards Using Navigation and Tab Bar Controllers

What You’ll Learn in This Hour:

• The purpose of navigation and tab bar controllers

• How to create navigation controller-based scenes with the storyboard

• How to build tab bar applications using the iOS tab bar template

• A way to share data between scenes using the navigation and tab bar controllers

These are useful and common user interface features, but many iOS applications take a more “structured” approach to scene layout.
