What is the best way to restore the state of ViewController

Question

I would like to ask some suggestion about how to restore a viewControllers state. Like in the app called \"Pic Collage\" when you create a card and save it and later restore

Answer 1

If you are supporting iOS 6 and above, take a look at State Preservation and Restoration. Even if you have to support older versions of iOS the documentation will guide you on when and how restoration can be achieved and the things you need to consider.
