Iphone app development - How do I reload(?) views?

Question

Okay, I'm working on a iPhone game. You start off on a menu screen, then select "New Game" or "High Scores". Let's select "New Game."

The first time you do this, you get an alert telling you how to play the game. I implemented this with the - (id)initWithNibName function. Here is the exact code:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {

//Alert Here

}
return self;

}

It works great. However, if I go back to the main menu, then return to the game screen, this alert does not pop up (it only pops up the first time the user clicks "New Game").

I am also using an viewDidLoad function, just as a side note.

Here is the code I am using to implement my nib (I believe):

        [mainViewController viewWillAppear:YES];
    [introViewController viewWillDisappear:YES];
    [introView removeFromSuperview];
    [self.view addSubview:mainView];
    [self.view insertSubview:menuButton aboveSubview:mainViewController.view];
    [introViewController viewDidDisappear:YES];
    [mainViewController viewDidAppear:YES];

Once again, Many Thanks

Try implementing the - (void) viewDidAppear:(BOOL)animated method to display the alert view. This will get called every time a view controller's view is added to a window.
