scene transition in iphone

Question

am using cocos2d now when user press start game .. game scene changes (using director)and game.png get loaded on screen but how to call my startGame() ,i mean where should i call my startgame() as i cant acces appdidfinishlauncing form here..

here is the code

// in app delegate class

(void)applicationDidFinishLaunching:(UIApplication *)application { printf("Loaded");

self.sliderController = [[SliderController alloc] init]; // 2

UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; [window addSubview:sliderController.view]; [window makeKeyAndVisible]; [window setUserInteractionEnabled:YES]; [window setMultipleTouchEnabled:YES];

[[Director sharedDirector] setLandscape: YES]; [[Director sharedDirector] attachInWindow:window];

[window makeKeyAndVisible];

MenuScene * ms = [MenuScene node];

[[Director sharedDirector] runWithScene:ms]; }

////// MenuScene class @implementation MenuLayer - (id) init { self = [super init]; if (self != nil) { [MenuItemFont setFontSize:20]; [MenuItemFont setFontName:@"Helvetica"]; MenuItem *start = [MenuItemFont itemFromString:@"Start Game1" target:self selector:@selector(startGame:)]; MenuItem *help = [MenuItemFont itemFromString:@"Help" target:self selector:@selector(help:)]; MenuItem *gei = [MenuItemFont itemFromString:@"gei" target:self selector:@selector(gei:)];

Menu *menu = [Menu menuWithItems:start, help, gei,nil];

[menu alignItemsVertically]; [self addChild:menu]; } return self; } -(void)startGame: (id)sender {

////// GameScene * gs = [GameScene node]; [[Director sharedDirector] replaceScene:gs];

/// in GameScene Class

(id) init { self = [super init]; if (self != nil) {

//SliderController *sc=[SliderController node]; // [[Director sharedDirector] replaceScene:sc];

printf("JHKHKHKHH"); Sprite * bg = [Sprite spriteWithFile:@"menu1.png"];

// [self initPuzzle:@"menu1.png"]; [bg setPosition:ccp(240, 160)]; [self addChild:bg z:0]; [self addChild:[GameLayer node] z:1];

// -(void) initPuzzle:(NSString *) imagePath; ////

but where should i call my startGame()? this is really a stupid question but .. i cant even solve this :(

Thanks
