How to set tab bar item title programmatically in objective c?

问题

I want to set title to tab item programatically, but it not works. My code is below:

- (IBAction)tab1Click:(id)sender {
    myTabBarController = [[UITabBarController alloc] init];        
    view2Controller = [[View2Controller alloc] init]; 
    [view2Controller setTitle:@"title"];
    view3Controller = [[View3Controller alloc] init];  
    deneme = [[ViewController alloc] init];  

    myTabBarController.viewControllers = [NSArray arrayWithObjects:deneme, view2Controller,view3Controller, nil]; 
    [self.view addSubview:myTabBarController.view];    
    myTabBarController.selectedIndex=1;
}

You can set all the UITabBar icons in an easy way. You can do this in your viewWillAppear: method:

[[self.tabBarController.tabBar.items objectAtIndex:0] setTitle:NSLocalizedString(@"BotonMapas", @"comment")];

[[self.tabBarController.tabBar.items objectAtIndex:1] setTitle:NSLocalizedString(@"BotonRA", @"comment")];

[[self.tabBarController.tabBar.items objectAtIndex:2] setTitle:NSLocalizedString(@"BotonEstado", @"comment")];

[[self.tabBarController.tabBar.items objectAtIndex:3] setTitle:NSLocalizedString(@"LabelInfo", @"comment")];

Swift 3.1 Solution

self.tabBarController?.tabBar.items?[0].title = NSLocalizedString("BotonMapas", comment: "comment")
self.tabBarController?.tabBar.items?[1].title = NSLocalizedString("BotonRA", comment: "comment")
self.tabBarController?.tabBar.items?[2].title = NSLocalizedString("BotonEstado", comment: "comment")
self.tabBarController?.tabBar.items?[3].title = NSLocalizedString("LabelInfo", comment: "comment")

How I do it in the actual View Controller (not the App Delegate):

// set tab title
self.title = @"Tab Title";
// optionally, set different title for navigation controller
self.navigationItem.title = @"Nav Title";
// Note: self.title will reset Nav Title. Use it first if you want different titles

回答3:

An easy way to do this : In your viewController2 's viewDidLoad method, set self.title = @"MyTitle";

回答4:

[view2Controller setTitle:@"ImATitle"];

might be what your after

edit: ok i just tested this and it def works for me so give it a go

UINavigationController *nav1 = [[UINavigationController alloc] init]; 
myViewController *myView = [[myViewController alloc] init];
//myView.title = @"Title"; //prob not needed
[nav1 pushViewController: myView  animated:NO];
UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"Title" image:[UIImage      imageNamed:@"title.png"] tag:0];
nav1.tabBarItem = item;
UITabBarController *tbc = [[UITabBarController alloc] init];
tbc.viewControllers = [NSArray arrayWithObjects:nav1, nil];

回答5:

The title displayed on a given tab bar item is determined by the corresponding view controller's instance of UITabBarItem. Those aren't mutable, though... if you want to change the title (or image, or tag), you have to make a new item and assign it to the view controller.

UITabBarItem *item2 = [[UITabBarItem alloc initWithTitle:@"someTitle" image:someImage tag:0];
viewController2.tabBarItem = item2;

回答6:

try this

[(UIViewController *)[tabBarController.viewControllers objectAtIndex:Index] setTitle:@"Title"];

or also you can set tab bar by in this way

UITabBarItem *tabItem = [[[tabBarController tabBar] items] objectAtIndex:INDEX];
[tabItem setTitle:@"TITLEe"];

回答7:

first declare UITabBarDelegate

- (IBAction)tab1Click:(id)sender {

    myTabBarController = [[UITabBarController alloc] init]; 

    myTabBarController.delegate = self;

    view2Controller = [[View2Controller alloc] init]; 
    [view2Controller setTitle:@"title"];
    view3Controller = [[View3Controller alloc] init];  
    deneme = [[ViewController alloc] init];  
    dename.title = @"Dename";
    view2Conreoller.title = @"View2";
    view3Conreoller.title = @"View3";
    myTabBarController.viewControllers = [NSArray arrayWithObjects:deneme, view2Controller,view3Controller, nil]; 
    [self.view addSubview:myTabBarController.view];    
    myTabBarController.selectedIndex=1;
}

and even you can set tab images using

view2Controller.tabBarItem.image = [UIImage imageNamed:@"misle.png"];

回答8:

If you are calling this from within an embedded UIViewController, you can change the parent tab bar title with:

self.tabBarController.title = @"My Title.";

回答9:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


    UITabBarController *tb=[[UITabBarController alloc]init];
    UIStoryboard *sb=[UIStoryboard storyboardWithName:@"Main"   bundle:nil];
    UIViewController *vc1=[sb   instantiateViewControllerWithIdentifier:@"View1"];
    UIViewController *vc2=[sb   instantiateViewControllerWithIdentifier:@"View2"];

      //To Set Title for UIViewController

      [vc1 setTitle:@"View1"];
      [vc2 setTitle:@"View2"];


    NSArray *vController=[[NSArray alloc]initWithObjects:vc1,vc2,nil];
    tb.viewControllers=vController;
    self.window.rootViewController=tb;
    [self.window makeKeyAndVisible];


  return YES;
}

In swift you can change the UITabBarController item's title in viewDidLoad: method as below-

   self.viewControllers![0].title="Deposit"
   self.viewControllers![1].title="Withdraw"
   self.viewControllers![2].title="Activity"
