Comment ajouter uitabbar dans iPhone en utilisant l'objectif c

- (void) setUpTabBar {
    FirstViewController *firstViewController = [[FirstViewController alloc]init];
    firstViewController.title = @"First View";
    firstViewController.tabBarItem = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemSearch tag:0];
    UINavigationController *firstNavController = [[UINavigationController alloc]initWithRootViewController:firstViewController];

    SecondViewController *secondViewController = [[SecondViewController alloc]init];
    secondViewController.title = @"Second View";
    secondViewController.tabBarItem = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemFavorites tag:1];
    UINavigationController *secondNavController = [[UINavigationController alloc]initWithRootViewController:secondViewController];

    ThirdViewController *thirdViewController = [[ThirdViewController alloc]init];
    thirdViewController.title = @"Third View";
    thirdViewController.tabBarItem = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemRecents tag:2];
    UINavigationController *thirdNavController = [[UINavigationController alloc]initWithRootViewController:thirdViewController];

    ForthViewController *forthViewController = [[ForthViewController alloc]init];
    forthViewController.title = @"Forth View";
    forthViewController.tabBarItem = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemHistory tag:2];
    UINavigationController *forthNavController = [[UINavigationController alloc]initWithRootViewController:forthViewController];

    tabBarController = [[UITabBarController alloc] initWithNibName:nil bundle:nil];
    tabBarController.viewControllers = [[NSArray alloc] initWithObjects:firstNavController, secondNavController, thirdNavController, forthNavController, nil];
    tabBarController.delegate = self;             
    [self sizeViewToAvailableWindow:[tabBarController view]];

    [firstNavController release];
    [firstViewController release];

    [secondNavController release];
    [secondViewController release];

    [thirdNavController release];
    [thirdViewController release];

    [forthNavController release];
    [forthViewController release];
}
Here is the code for making TabBarController programmatically.
Hope this will help you.

Voici ce que vous pouvez faire

    SubClassViewController1* vc1 = [[SubClassViewController1 alloc] init];
    UINavigationController* nav1 = [[UINavigationController alloc] initWithRootViewController:vc1];
    nav1.navigationBar.hidden = YES;
    [vc1 release]; vc1 = nil;

    SubClassViewController2* vc2 = [[SubClassViewController2 alloc] init];
    vc2.title = @"List";
    UINavigationController* nav2 = [[UINavigationController alloc] initWithRootViewController:vc2];
    nav2.navigationBar.hidden = YES;
    [vc2 release]; vc2 = nil;

    SubClassViewController3* vc3 = [[SubClassViewController3 alloc] init];
    vc3.title = @"Scan";
    UINavigationController* nav3 = [[UINavigationController alloc] initWithRootViewController:vc3];
    nav3.navigationBar.hidden = YES;
    [vc3 release]; vc3 = nil;

    SubClassViewController4* vc4 = [[SubClassViewController4 alloc] init];
    vc4.title = @"Setting";
    UINavigationController* nav4 = [[UINavigationController alloc] initWithRootViewController:vc4];
    nav4.navigationBar.hidden = YES;
    [vc4 release]; vc4 = nil;

    UITabBarController* tabBar = [[UITabBarController alloc] init];
    [tabBar setViewControllers:[NSArray arrayWithObjects:nav1,nav2,nav3,nav4,nil]];

    [self.navigationController pushViewController:tabBar animated:YES];
    [nav1 release]; nav1 = nil;
    [nav2 release]; nav2 = nil;
    [nav3 release]; nav3 = nil;
    [nav4 release]; nav4 = nil;
    [tabBar release]; tabBar = nil;

Vous pouvez faire quelque chose comme: xxx

pour ajouter des éléments à celui-ci, vous pouvez écrire: xxx

ici les deux aspects ...

premier aspect ( uitabbarcontroller strong>): Ici, vous pouvez ajouter plusieurs classes (i.e ViewControlers) à l'UitabbarController comme indiqué dans les réponses précédentes ... p>

deuxième aspect ( uitabbar strong>): Ici, vous pouvez ajouter la barre à tabulation dans n'importe quel contrôleur d'affichage ... et pour cette barre d'onglets, vous pouvez ajouter plusieurs éléments uitabbar. Et vous pouvez obtenir l'action individuelle de la barre d'onglets ..... p>

Voir le code ci-dessous Pour uitabbar strong> p>

---------> Ajout d'uitabbar strong> p>

func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem) {
    let selectedTag:Int = (tabBar.selectedItem?.tag)!
    print(selectedTag)
    switch selectedTag {
    case 0:
        print("tabBarItem1")
        //Do what ever you want here
    case 1:
        print("tabBarItem2")
        //Do what ever you want here
    case 2:
        print("tabBarItem3")
        //Do what ever you want here
    default:
        print("tabBarItem4")
        //Do what ever you want here
    }
}
