Ios5 如何在ios中的cocos2dv3.x中设置两个不同的启动屏幕

我正在使用cocos2d 3.x和Xcode 5.1.1。我有两个图像image1.png和image2.png。在我的游戏中，我已经将默认图像（启动屏幕）更改为我的图像（image1.png）。在这里，我需要将image1.png显示2秒，将image2.png显示3秒，作为我游戏的初始屏幕…提前感谢..

我就是这样做的（在iOS提供默认图像后淡入淡出徽标。我有一个SplashLogo类（场景）。这是我的启动场景，它挂上徽标，淡出，然后用我的游戏控制器将自己替换为运行场景

- (void)onEnter {

    [super onEnter];

    self.positionType = CCPositionTypePoints;
    // todo : test this background seed, GL side effects, timing, etc ...    
    // [self performSelectorInBackground:@selector(seedGameSequencer) withObject:nil];

    [self seedGameSequencer];
    CCColor     *color = [CCColor colorWithRed:0 green:0.f blue:0.f alpha:0.f];
    CCNodeColor *black = [CCNodeColor nodeWithColor:color];
    black.positionType = CCPositionTypePoints;
    black.position    = ccp(0, 0);
    black.anchorPoint = ccp(0, 0); // bottom left
    [self addChild:black];


    [GESprite mediumPixelFormat];
    CCSprite *logo = [CCSprite spriteWithImageNamed:@"maxPowerStudiosLogo.png"];
    logo.positionType = CCPositionTypePoints;
    logo.anchorPoint = ccp(.5, .5);
    logo.opacity          = 0;
    logo.positionInPoints = ccp(black.contentSizeInPoints.width / 2, black.contentSizeInPoints.height / 2);

    [GESprite defaultPixelFormat];

    id fadein          = [CCActionFadeIn actionWithDuration:3 * K_FADE_TIME];
    id taponne         = [CCActionDelay actionWithDuration:.95];
    id fadeout         = [CCActionFadeOut actionWithDuration:2 * K_FADE_TIME];
    id swapSceneAction = [CCActionCallFunc actionWithTarget:self selector:@selector(swapScene)];
    id seq             = [CCActionSequence actions:fadein, taponne, fadeout, swapSceneAction, nil];

    // add the label as a child to this Layer

    [self addChild:logo];
    [logo runAction:seq];

}

- (void)seedGameSequencer {

    mainScene = [MPGameSequencer scene];
}

- (void)swapScene {

    [[CCDirector sharedDirector] replaceScene:mainScene];

}

在AppDelegate中：

- (CCScene *)startScene {
    // This method should return the very first scene to be run when your app starts.
    return [SplashLogo scene];
}

哇，对于一个不清楚的问题，投了很多赞成票！什么是“第一个图像”到“第二个图像”到“启动屏幕”到“默认图像”……它们之间有什么联系吗？？？在什么情况下需要什么显示2秒，在什么情况下需要另一个纹理显示3秒？
