UINavigationBar - Set title programmatically?

I have a tab bar application with a different view on each tab. Each view has a UINavigationBar with title set on Interface Builder. I want to change the title based on a clause in the ViewDidLoad method, so if x { change the title }.

I have tried self.title = @"title", but this changes the title of the tab bar item itself.

So, how is this done?

I've set the title programmatically using code something like this:

navBar.topItem.title = @"title";

where navBar is declared as an IBOutlet UINavigationBar linked to the navigation bar in interface builder. This worked in my app; however, I was not using a tab bar.

If navBar.topItem is the tab bar item, I don't see a way for you to change the title that appears on the navigation bar without also changing the title on the tab bar item, since the navBar's topItem and the tab bar item is the same object.

Use

self.navigationItem.title = @"the title";

as setting navBar.topItem.title will not work in all circumstances.

Use this :

    CGRect navBarFrame = CGRectMake(0, 0, self.tableView.frame.size.width, 44.0);
    UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:navBarFrame];
    
    UINavigationItem *navItem = [UINavigationItem alloc];
    navItem.title = @"Your Title";
    
    [navBar pushNavigationItem:navItem animated:false];

[self.view addSubView:navBar]; 

or

self.tableView.tableHeaderView = navBar; etc

If the class is a type of UIViewController, then you can set title as given in the viewDidLoad method.

    [self setTitle:@"My Title"];

 

Create IBOutlet of UINavigationBar

navigationBar.topItem.title = @"Title";

Hope this helps.

In ViewDidLoad of your ViewController.m just write,

self.navigationItem.title=@"Hello World";

Here is the Output:

I used the following:

self.navigationController.navigationBar.topItem.title = @"Title";

However, I also had to call it in a dispatch block as it wouldn't change the title when called within the viewDidLoad w/o it.

Note that in order for the title to show up AT ALL the Navigation Controller's delegate MUST be set to the navigation bar itself or the title will NEVER show!

You can also just set the title in the ViewDidLoad under your ViewController or TableViewController using

_title = @"Title";

or

self.title = @"Title";

I achieved this way in Swift 5

override func viewDidLoad() {
    super.viewDidLoad()
    navigationItem.title = "Title"
}

Try this,

self.navigationItem.title = @"Your title";
