Question

I would like to add a Welcome view to my app which describes the instructions etc.

I would like this to appear only once when the app is first launched… then with subsequent launches go to my app’s main view… which is a navigation controller.

What is the best way to track launches/ implement this idea?

Thanks.

Answer 1

In your root controller of a navigation controller (the view controller that is normally visible as first one), activate a modal controller with those initial instructions with presentModalViewController:animated:.

You probably want to call it from within viewWillAppear:. Do not animate presenting of modal view controller (otherwise you see what’s below), but animate when dismissing it – it looks really elegant.

Use UserDefaults to store the information that it had already been shown, and do not show it anymore.
