Setting Back Button Tittle in Navigation Controller problem

Question

Hi,

I'm trying to change Back Button tittle in a navigation controller in the following way:

In the parent controller I put this in vieDidLoad:

self.title = @"Calendars";
self.navigationItem.backBarButtonItem.title = @"Previous";

But this controller is in the stack since I initialized the app:

-(void)applicationDidFinishLaunching:(UIApplication *)application{

navController.viewControllers= [NSArray arrayWithObjects:aController,aBcontroller,nil];
[window addSubview:navController.view];

}

So, the viewDidLoad in aController is not called until I select the back buttom the first time in the bController...

Does anyone knows how to call viewDidLoad just when I push it into the stack? Or do you know another way to change the BackButtom title?

Thanks in advanced for your help.

Answer 1

You should put your code to set up the title and navigationItem in init, you don't need to wait until the view is loaded.

Answer 2

You can set the title of the back button for any ViewController you're in with the following line of code:

self.navigationController.navigationBar.backItem.title = @"Previous";
