navigationController title

问题

I am working on an app with a navigation controller. I know how to set the title when the view loads initially. I push a new view controller and set it's title. Now the problem is when I press the back button, the title for the original view controller is not there anymore. I tried to do...

- (void)viewWillAppear:(BOOL)animated {
    self.navigationController.title = @"Some Title";
}

This did not set the title though. Does anyone know what I can do?

回答1:

The UINavigationController gets the value for the title from the current UIViewController.

To set a the title for a view Controller, simply do the following:

- (void)viewDidLoad {

   [super viewDidLoad];
   self.title = @"Some Title";
}

For each of your View Controllers, including the root one.

Try changing the navigation item's title.

[self.navigationItem setTitle:@"Some Title"];

回答3:

in Swift 3:

navigationItem.title = "Custom title"

or if you want to customize the details of the title:

let titleLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 100, height: 30))
titleLabel.textColor = UIColor.red
titleLabel.text = "Hello"
titleLabel.textAlignment = .center
titleLabel.backgroundColor = UIColor.green
titleLabel.font = UIFont(name: "Baskerville-Bold", size: 20)
navigationItem.titleView = titleLabel

Try setting your title this way.

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