Hey all. I'm still pretty new to iPhone development, and I'm having a bit of trouble figuring out how to change the title of my Navigation Bar. On another question on this site somebody recommended using :
viewController.title = @"title text";
but that isn't working for me...Do I need to add a UINavigationController to accomplish this? Or maybe just an outlet from my UIViewController subclass? If it helps, I defined the navigation bar in IB and I'm trying to set its title in my UIViewController subclass. This is another one of those simple things that gives me a headache. Putting self.title = @"title text"; in viewDidLoad and initWithNibName didn't work either. Anybody know what's happening and how to get it happening right?
Thanks!

The view controller must be a child of some UINavigationController for the .title property to take effect. If the UINavigationBar is simply a view, you need to push a navigation item containing the title, or modify the last navigation item:
ReplyDeleteUINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@"title text"];
...
[bar pushNavigationItem:item animated:YES];
[item release];
or
bar.topItem.title = @"title text";
if you are doing it all by code in the viewDidLoad method of the UIViewController you should only add self.title = @"title text";
ReplyDeletesomething like this:
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"title";
}
you could also try self.navigationItem.title = @"title";
also check if your navigationItem is not null and if you have set a custom background to the navigationbar check if the title is set without it.
There's one issue with using self.title = @"title";
ReplyDeleteIf you're using Navigation Bar along with Tab bar, the above line also changes the label for the Tab Bar Item. To avoid this, use what @testing suggested
self.navigationItem.title = @"MyTitle";
In my navigation based app I do this:
ReplyDeletemyViewController.navigationItem.title = @"MyTitle";
I guess you need a dynamic title that is why you don't set it in IB.
ReplyDeleteAnd I presume your viewController object is the one specified in the NIB?
Perhaps trying setting it to a dummy value in IB and then debug the methods to see which controller has the dummy value - assuming it appears as the title...
By default the navigation controller displays the title of the 'topitem'
ReplyDeleteso in your viewdidload method of your appdelegate you can. I tested it and it works
navController.navigationBar.topItem.title = @"Test";
UINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@"title text"];
ReplyDelete...
[bar pushNavigationItem:item animated:YES];
[item release];
This code worked.
I had a navigation controllers integrated in a TabbarController. This worked
ReplyDeleteself.navigationItem.title=@"title";
