Add Elements to Navigation Bar

[alexgiul]

Hi,

I have a navigation app and when I start the app, the first view is a table;

on it I have successfully added a "edit" and "about" button following the guide.

Now when I click on "about" I open a new view (derived from UIViewController") and I try to add a new item on the navigation bar to customize the behaviour but the button on this second view doesn't appear...neither the title of the view

I put

- (void)viewDidLoad {
	
    self.title= @"About"
	
	UIBarButtonItem *settingsButton = [[[UIBarButtonItem alloc] 
									initWithTitle:@"Settings" 
									style:UIBarButtonItemStylePlain 
									target:self 
									action:@selector(openSettings)] autorelease]; 
    
	self.navigationItem.leftBarButtonItem = settingsButton;
	[settingsButton release];
	[super viewDidLoad];
}

Where am I wrong?

- (void)viewDidLoad {
	
   self.title= @"About"
	
   UIBarButtonItem *settingsButton = [[[UIBarButtonItem alloc] 
      initWithTitle:@"Settings" 
      style:UIBarButtonItemStylePlain 
      target:self 
      action:@selector(openSettings)] autorelease]; 
    
   self.navigationItem.leftBarButtonItem = settingsButton;
   [settingsButton release];
   [super viewDidLoad];
}

Too many releases.

I removed the la "release" but nothing change...
could be the problem the type of View hich is a UIViewController?

How do you go from the first view controller to the second one?

With the code in the previous post

No you don't. You're creating a button with the previous code. What does the button do?

Hint: Post openSettings

[Error404]

If you use a navigation bar, you should have your "settingsButton" on the right hand side, becuase the regular back button will be on the right, which might cause problems.

self.navigationItem.leftBarButtonItem = settingsButton;

Also, try to remove the autorelease and just keep the normal release at the end.
