UItabBar из второго контроллера представления, но все viewController имеют UInavigation с возвратом к первому вопросу ViewController

Question

UItabBar из второго контроллера представления, но все viewController имеют UInavigation с возвратом к первому вопросу ViewController

Позвольте мне сначала объяснить мое заявление. У меня шесть контроллеров вида

MenuViewController
FirstViewController
SecondViewController
ThirdViewController
FourthViewController
FifthViewController

Все эти 6 ViewControllers находятся в navigationController. Я хочу показать мой "MenuViewController" сначала во время запуска приложения, после заставки, которая содержит 5 кнопок (для:FirstViewController, SecondViewController, ThirdViewController, FourthViewController, FifthViewController). В этом viewController внизу страницы не будет TabBarController. Но другой viewController будет в tabbarController. Когда я касаюсь одной из этих пяти кнопок в menuviewController, он приводит меня к соответствующему контроллеру представления, где я могу найти tabbarController внизу. Я могу сделать это с пользовательским кодированием, позиционированием и настройкой изображения позади них. Вот код:

AppDelegate.h:

@interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>
{
    UIImageView *firstTabImageView;
    UIImageView *secondTabImageView;
    UIImageView *thirdTabImageView;
    UIImageView *fourthTabImageView;
    UIImageView *fifthTabImageView;

    UIImage *firstTabImage;
    UIImage *firstTabActiveImage;

    UIImage *secondTabImage;
    UIImage *secondTabActiveImage;

    UIImage *thirdTabImage;
    UIImage *thirdTabActiveImage;

    UIImage *fourthTabImage;
    UIImage *fourthTabActiveImage;

    UIImage *fifthTabImage;
    UIImage *fifthTabActiveImage;
}

@property (strong, nonatomic) MenuViewController *menuViewController;
@property (strong, nonatomic) UINavigationController *navigationController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    [self makeTabBar];

    MenuViewController *menuViewController = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil];
    navigationController = [[UINavigationController alloc] initWithRootViewController:menuViewController];
    self.window.rootViewController = self.navigationController;
    [self.window makeKeyAndVisible];

    return YES;
}

Я использую этот код для каждого "IBAction" с другим индексом: Например: "FirstViewController" с "index: 0"

- (IBAction)GotoFirstViewController:(id)sender
{
    AppDelegate *appdelegte = (AppDelegate*)[[UIApplication sharedApplication] delegate];
    [[[appdelegte navigationController] view]removeFromSuperview];
    [[appdelegte window] addSubview:[[appdelegte tabBarController] view]];
    [[appdelegte tabBarController] setSelectedIndex:0];
}

Теперь проблема заключается в переходе к ViewController и возвращению к "MenuViewController", используя этот код:

-(IBAction)goBack:(id)sender
{
    menuViewController = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil];
    [self.navigationController pushViewController:menuViewController animated:YES];
}

Я не могу перейти к другому ViewController (любой из пяти), нажав ту же кнопку. Если кто-то знает, когда панель вкладок настраивается из "seceondViewController (Здесь: firstViewController)", то после перехода в "firstViewController (здесь: menuViewController)" из другого ViewController, как снова перейти в другой ViewController, связанный с tabbar, Пожалуйста, поделитесь со мной. Большое спасибо за чтение этого поста и большое спасибо заранее. - Тулон

Основанный на документации Apple, UITabBar является подклассом UIViewController и может быть дочерним. View..! Но это должен быть UIWindow rootController, если не произойдет сбой вашего приложения!!! У меня была та же проблема в конце, мне пришлось использовать UIToolBar, чтобы сделать то же самое... хотя и с очень тяжелой работой по настройке.

Добавьте этот код на свой AppDelegate.m

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController
{
    self.tabBarController.selectedViewController=viewController;
    return YES;
}
