Question

Is there a way to know for sure that the app has been launched from scratch, meaning it hasn’t been awaked from the background but really started up out of nowhere including the display of Default.png or Default-iPad.png?

Answer 1

In your App delegate there is a method,

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Only at launch" message:@""   delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
   [alert show];
}
