Answer 1

Попробуйте это, чтобы удалить навигационную панель.

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 
    // Override point for customization after application launch. 
    MasterViewController *masterViewController = [[[MasterViewController alloc] initWithNibName:@"MasterViewController" bundle:nil] autorelease]; 
    self.window.rootViewController = masterViewController; 
    [self.window makeKeyAndVisible]; return YES; 
}

Установить свойство navigationBarHidden, чтобы скрыть навигацию. Для справки см. Документацию UINavigationController.

Добавьте приведенный ниже оператор к вашему методу didFinishLaunchingWithOptions.

[self.navigationController setNavigationBarHidden:YES animated:YES];
