Warning: Attempt to present <SplashViewController: 0x1dd697b0> on <AdViewController: 0x1dd68690> whose view is not in the window hierarchy! et pas en mesure de naviguer vers ma prochaine vue qui est SplashViewController..J'ai essayé toutes les méthodes ci-dessous est le code.Pour vous les gars m'aider:

Pourquoi vous présenterez vue sur l'auto si vous définissez la vue racine des fenêtres à splashViewController?

appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate]; 
appDelegate.window.rootViewController = appDelegate.splashViewController; 
[self presentModalViewController:appDelegate.splashViewController animated:NO]; 

utiliser cette place

appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate]; 
//appDelegate.window.rootViewController = appDelegate.splashViewController; 
[appDelegate.window presentModalViewController:appDelegate.splashViewController animated:NO];
