The document discusses different types of view controller transitions in iOS, including pushing a view controller using a navigation controller, presenting a view controller modally, and creating custom transitions by implementing various view controller transitioning protocols. It also mentions using segues to trigger transitions and pass data, and provides a sample app demonstration and references for more information.

ViewController Transitions

3. What’s the plan ?
• Common built-in transitions
• Pushing a view controller
• Presenting a view controller
• Custom transition
• Segue ? 👀
• Demonstration with a sample app
• References

4. Pushing
a View Controller

5. - The view controller has to be contained into an UINavigationController to be able
to perform the « push » transition
- This transition doesn’t work if performed by example in a simple UIViewController

6. Presenting
a View Controller

8. modalPresentationStyle = .fullScreen modalPresentationStyle = .automatic
vs
iOS 12 iOS 13

9. Customizing
the transition animation

10. - View controller have to implement
UIViewControllerTransitioningDelegate protocol
- The animation controller must implement
UIViewControllerAnimatedTransitioning protocol in order to provide methods
like animateTransition(using:) in order to perform the animation
- Make it interactive by implementing
UIViewControllerInteractiveTransitioning protocol in our
animation controller

11. Segue ? 👀
For transitions, pass data …

12. Create a Segue

13. Pass data through segue
