Why does didLoad not fire?

I have a startup view 开发者_如何学运维controller which has the following:

- (void)viewDidLoad {
    [self loadMainMenu:nil];
    [super viewDidLoad];
}

This does the following:

-(IBAction) loadMainMenu:(id) sender {
      [self.view insertSubview:mainMenuViewController.view atIndex:0];
}

My mainMenu.h has the following:

-(IBAction) loadRules:(id) sender;
-(IBAction) loadPlayGame:(id) sender; 
-(IBAction) loadHighScores:(id) sender;
-(IBAction) loadAbout:(id) sender;

mainMenu.m has the below and has a button tied to this in order to show the view:

-(IBAction) loadPlayGame:(id) sender {
playGame *playGameViewController = [[rules alloc]
                                initWithNibName:@"playGame"
                                bundle:nil];

    [self setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
    [self presentModalViewController:playGameViewController animated:YES];
    [playGameViewController release];
}

Now the View for playGame does come up but the viewDidLoad never gets hit.

What am I doing wrong? Is this not the way to load the view? As always, thanks in advance for any and all help.

BTW: The code: [self setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; does nothing...any and all view show up as a croll up from bottom.

Geo...

This code makes no sense:

playGame *playGameViewController = [[rules alloc]
                            initWithNibName:@"playGame"
                            bundle:nil];

What is rules here? Is it a instance variable? It should the the class name of a view controller. Like for example PlayGameViewController.

Either you are doing that wrong or your naming conventions for classes and nibs are very wrong.
