He estado jugando con la restauración del estado. En el código a continuación, la posición de desplazamiento del UITableViewController se restaura, sin embargo, si tuviera que acceder a la vista de detalles (empujando una instancia de MyViewController en la pila de navegación), cuando la aplicación se reinicia, siempre volverá a la primera vista. controlador en la pila de navegación (es decir, MyTableViewController). ¿Alguien podría ayudarme a restaurar el controlador de vista correcto (es decir, MyOtherViewController)?

        // Override point for customization after application launch.


        MyTableViewController *table = [[MyTableViewController alloc] initWithStyle:UITableViewStylePlain];
        table.depth = 0;
        UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:table];
        navCon.restorationIdentifier = @"navigationController";

        self.window.rootViewController = navCon;

        self.window.backgroundColor = [UIColor whiteColor];
        [self.window makeKeyAndVisible];
