viewDidLoad issue - objective-c

Question

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.

Answer 1

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];
}
