viewDidLoad issue

I am having problem with ViewDidLoad Method.I have one .Xib File in my app and 5 viewControlelr.And Each View Controller Contains some initialization and method calls.

Problem is at the startup all the ViewDidLoad method runs.

Is there any way i can do this just when my ViewController will be called and the View is Loaded on the screen?

What is the proper way in this case?

I tried like this code :

  -(void)viewDidAppear
    {

    [ScoreWebView loadRequest:[NSURLRequest requestWithURL:[NSURL    URLWithString:@"http://smwebtech.com/Pandit/web_service/getScore.php?u=aa"]]];

     }

But my program is not reaching this method.Why?Am i missing something?Please take a look.

Use viewWillAppear method instead. It is only called when the view is going to appear on screen.

Or viewDidAppear which is only called after the view appears on screen.

EDIT:

Both viewWillAppear and viewDidAppear take a BOOL argument each:

- (void)viewWillAppear:(BOOL)animated {
}

- (void)viewDidAppear:(BOOL)animated {
}

EDIT2:

These two delegate methods have their corresponding 'opposite' methods that you can override to release resources you allocate in the former methods:

- (void)viewWillDisappear:(BOOL)animated {
    [resource release];
    [super viewWillDisappear:animated];
}

- (void)viewDidDisappear:(BOOL)animated {
    [resource release];
    [super viewDidDisappear:animated];
}
