カスタムタブバーにナビゲーションバーが表示されない

Question

現在、私はマルチストーリーボードプロジェクトで作業しており、UIViewController内にカスタムUIView（「Tab Bar VC」という名前）を作成して見せます
https://github.com/codepath/ios_guides/wiki/Creating-a-Custom-Tab-Bar
すべてが正常に表示されますが、タブバーの項目を押すと、ナビゲーションバーが表示されず、別のビューコントローラーにプッシュできません。それ。私はこの画像のようにナビゲーションコントローラに「Tab Bar VC」を埋め込もうとしましたが、うまくいきません：
私の場合はUITabBarViewControllerまたはStoryboard Referenceを使用したくありません。私を助けてください。
ありがとうございます。ここで タブバーVCの私のコードです：

#import "SHTabViewController.h" 
#import "SHHomeViewController.h" 
#import "SHTicketViewController.h" 
#import "SHNotificationViewController.h" 
#import "SHChatViewController.h" 
#import "SHCallViewController.h" 

@interface SHTabViewController() { 
    NSMutableArray *viewcontrollers; 
    NSInteger selectedIndex; 
} 
@property (weak, nonatomic) IBOutlet UIView *contentView; 
@property (strong, nonatomic) IBOutletCollection(UIButton) NSArray *tabButtons; 
@property (strong, nonatomic) SHHomeViewController *homeVC; 
@property (strong, nonatomic) SHCallViewController *callVC; 
@property (strong, nonatomic) SHChatViewController *chatVC; 
@property (strong, nonatomic) SHTicketViewController *ticketVC; 
@property (strong, nonatomic) SHNotificationViewController *notifVC; 

@end 

@implementation SHTabViewController 

-(void)viewWillAppear:(BOOL)animated { 
    [super viewWillAppear:animated]; 
    selectedIndex = 0; 
} 

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
    selectedIndex = 0; 
    UIStoryboard *homeStoryboard = [UIStoryboard storyboardWithName:@"Home" bundle:[NSBundle mainBundle]]; 
    UIStoryboard *callStoryboard = [UIStoryboard storyboardWithName:@"CallPM" bundle:[NSBundle mainBundle]]; 
    UIStoryboard *chatStoryboard = [UIStoryboard storyboardWithName:@"Chat" bundle:[NSBundle mainBundle]]; 
    UIStoryboard *ticketStoryboard = [UIStoryboard storyboardWithName:@"Ticket" bundle:[NSBundle mainBundle]]; 
    UIStoryboard *notifStoryboard = [UIStoryboard storyboardWithName:@"Notification" bundle:[NSBundle mainBundle]]; 

    self.homeVC = [homeStoryboard instantiateViewControllerWithIdentifier:@"homeVC"]; 
    self.callVC = [callStoryboard instantiateViewControllerWithIdentifier:@"callVC"]; 
    self.chatVC = [chatStoryboard instantiateViewControllerWithIdentifier:@"chatVC"]; 
    self.ticketVC = [ticketStoryboard instantiateViewControllerWithIdentifier:@"ticketVC"]; 
    self.notifVC = [notifStoryboard instantiateViewControllerWithIdentifier:@"notificationVC"]; 
    viewcontrollers = [NSMutableArray new]; 
    [viewcontrollers addObject:self.homeVC]; 
    [viewcontrollers addObject:self.callVC]; 
    [viewcontrollers addObject:self.chatVC]; 
    [viewcontrollers addObject:self.ticketVC]; 
    [viewcontrollers addObject:self.notifVC]; 

    [self.tabButtons[selectedIndex] setSelected:YES]; 
    [self didPressTab:self.tabButtons[selectedIndex]]; 
} 

- (void)didReceiveMemoryWarning { 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 

- (IBAction)didPressTab:(UIButton *)sender { 
    selectedIndex = 0; 
    sender.selected = YES; 
    NSInteger previousIndex = selectedIndex; 
    selectedIndex = sender.tag; 
    [self.tabButtons[previousIndex] setSelected:NO]; 
    UIViewController *previousVC = viewcontrollers[previousIndex]; 
    [previousVC willMoveToParentViewController:nil]; 
    [previousVC.view removeFromSuperview]; 
    [previousVC removeFromParentViewController]; 

    UIViewController *vc = viewcontrollers[selectedIndex]; 
    [self addChildViewController:vc]; 
    vc.view.frame = self.contentView.bounds; 
    [self.contentView addSubview:vc.view]; 
    [vc didMoveToParentViewController:self]; 
} 

Answer 1

UINavigationViewControllerと 'タブバーVC' を埋め込まないでください。 'Tab bar VC'に追加した個々のUIViewControllerのそれぞれにUINavigationViewControllerを埋め込みます。

Answer 2

すべての個別ビューコントローラをナビゲーションコントローラに埋め込む必要があります。

TabBarController> NavigationController>のViewController

Answer 3

For this you need to add a NavigationController for every Controllers like below 


    -(void)viewDidLoad { 
     [super viewDidLoad]; 
     // Do any additional setup after loading the view. 
     selectedIndex = 0; 
     UIStoryboard *homeStoryboard = [UIStoryboard storyboardWithName:@"Home" bundle:[NSBundle mainBundle]]; 
     UIStoryboard *callStoryboard = [UIStoryboard storyboardWithName:@"CallPM" bundle:[NSBundle mainBundle]]; 
     UIStoryboard *chatStoryboard = [UIStoryboard storyboardWithName:@"Chat" bundle:[NSBundle mainBundle]]; 
     UIStoryboard *ticketStoryboard = [UIStoryboard storyboardWithName:@"Ticket" bundle:[NSBundle mainBundle]]; 
     UIStoryboard *notifStoryboard = [UIStoryboard storyboardWithName:@"Notification" bundle:[NSBundle mainBundle]]; 

     self.homeVC = [homeStoryboard instantiateViewControllerWithIdentifier:@"homeVC"]; 
     self.callVC = [callStoryboard instantiateViewControllerWithIdentifier:@"callVC"]; 
     self.chatVC = [chatStoryboard instantiateViewControllerWithIdentifier:@"chatVC"]; 
     self.ticketVC = [ticketStoryboard instantiateViewControllerWithIdentifier:@"ticketVC"]; 
     self.notifVC = [notifStoryboard instantiateViewControllerWithIdentifier:@"notificationVC"]; 

    UINavigationController *homeNavController = [[UINavigationController alloc] initWithRootViewController: self.homeVC]; 
    UINavigationController *callVCNavController = [[UINavigationController alloc] initWithRootViewController: self.callVC]; 
    UINavigationController *chatVCNavController = [[UINavigationController alloc] initWithRootViewController: self.chatVC]; 
    UINavigationController *ticketVCNavController = [[UINavigationController alloc] initWithRootViewController: self.ticketVC]; 
    UINavigationController *notifVCNavController = [[UINavigationController alloc] initWithRootViewController: self.notifVC]; 


     viewcontrollers = [NSMutableArray new]; 
     [viewcontrollers addObject: homeNavController]; 
     [viewcontrollers addObject: callVCNavController]; 
     [viewcontrollers addObject:ticketVCNavController]; 
     [viewcontrollers addObject:chatVCNavController]; 
     [viewcontrollers addObject: notifVCNavController]; 

     [self.tabButtons[selectedIndex] setSelected:YES]; 
     [self didPressTab:self.tabButtons[selectedIndex]]; 

Answer 4

あなたは間違ったアプローチを使用しています。あなたは論理的に意味をなさないナビゲーションコントローラにタブバーコントローラを埋め込みます。その代わりに、さまざまなナビゲーションコントローラを1つのタブバーコントローラに埋め込む必要があります。次のようなことを試してみてください：
