I’ve made a simple single view program in xcode 4.3.1. I’d like the view to do different things depending on if it is being loaded the first time the application starts vs when it is being resumed.

Can anyone tell me the best way to do this?

The appDelegate has no reference to my viewController so I’m not sure I can pass a variable from my AppDelegate didFinishLaunchingWithOptions method.

How does the AppDelegate communicate with the ViewController when the ViewController does not seem to be instantiated anywhere?

Thanks!

    You can use [application:didFinishLaunchingWithOptions:] to determine if you just started. It is only called once when you launch. You can combine that with setting some flags and
    [applicationWillEnterForeground:(UIApplication *)application] to determine if you launched or are simply returning to the foreground.
