私はiOSを初めて使用しますが、タブバーコントローラーに問題がありました。プロジェクトで2つのタブバーコントローラーを使用しています.1つはアプリのランチに読み込まれ、正常に機能しています.didselect行にもう1つを読み込みたいです。これを行う方法。私は多くの実験を行いましたが、何も機能しません。

-(void) hidetabbar {

when u r clicking on the table view did select row hide the tabbar in the viewcontroller that u r sending
-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:YES];
    [((AppDelegate*)[[UIApplication sharedApplication]delegate]) hidetabbar];
}
-(void)tabBarControllerView
{
    tabBarController = [[UITabBarController alloc] init];
    tabBarController.view.backgroundColor = [UIColor blackColor];
    tabBarController.delegate = self;
    //Add some tabs to the controller...
    //----First tab----//
    //-----second Tab   -----//
    //------3rd tab--//
    //-----4th tab bar--------//
    //-----5th tab bar--------//
    [self.view addSubview:tabBarController.view];
    [navigationController pushViewController:tabBarController animated:YES];
    tabBarController.tabBar.tag=100;
    tabBarController.view.hidden = NO;
}
- (void)tabBarController:(UITabBarController *)tabBarControllers didSelectViewController:(UIViewController *)viewController  
{
    if (tabBarControllers.selectedIndex == 0)
    {
    }
    else if (tabBarControllers.selectedIndex == 1)
    {
    }
    else if (tabBarControllers.selectedIndex == 2)
    {
    }
    else if (tabBarControllers.selectedIndex == 3)
    {
    }
    else if (tabBarControllers.selectedIndex == 4)
    {
    }
}
そのViewControllerでメインタブバーを非表示にします。ここで、テーブルを選択し、別のタブバーを追加します。このようなことを試してみてください。

didSelect イベントに次のコードを追加します。
 UITabBarController *tabBarController = [[UITabBarController alloc]init];
    NSArray*tabBarimageArray=[NSArray arrayWithObjects:@"firstTabImage.png",@"secondTabImage.png", nil];
    YourFirstTabRootViewController *firstVc = [[YourFirstTabRootViewController alloc]initWithNibName:@"YourFirstTabRootViewController" bundle:nil];
    UINavigationController *firstNavigationController=[[UINavigationController alloc]initWithRootViewController:firstVc];
    YourSecondTabRootViewController *secondVc = [[YourSecondTabRootViewController alloc]initWithNibName:@"YourFirstTabRootViewController" bundle:nil];
    UINavigationController *secondNavigationController=[[UINavigationController alloc]initWithRootViewController:secondVc];
    NSArray *VCs = [[NSArray alloc] initWithObjects:firstNavigationController,secondNavigationController nil];
    NSArray *names = [NSArray arrayWithObjects:
                      NSLocalizedString(@"Tab1", @""), 
                      NSLocalizedString(@"Tab2", @""),
                      nil];
    NSMutableArray *tabBarViewControllers = [[NSMutableArray alloc] initWithCapacity:[VCs count]];
    NSInteger index = 0;
    for (id controller in VCs) {
        UINavigationController * navController = controller ;
                // THIS SETS UP THE TAB BAR ITEMS/IMAGES AND SET THE TAG FOR TABBAR_ITEM_TAGS
                NSString *tabName = [names objectAtIndex:index];
                UIImage *tabImage = [UIImage imageNamed:[NSString stringWithFormat:[tabBarimageArray objectAtIndex:index]]];
                navController.title = tabName;
                UITabBarItem *tempTab = [[UITabBarItem alloc] initWithTitle:tabName 
                                                                      image:tabImage 
                                                                        tag:index];
                navController.tabBarItem = tempTab;
                [tabBarViewControllers addObject:navController];
        index ++;
        }
    [ tabBarController setViewControllers:tabBarViewControllers];
    [self presentModalViewController:tabBarController animated:YES];
