我希望在游戏上线前制作一些自定义图片（例如一些游戏开发者的logo和信息）。在cocos2d Temple中，只有一个IntroLayer来显示logo，所以我决定在进入之前添加更多场景来显示其他信息游戏的主菜单。在 IntroLayer.h

//this is the template code    
@interface IntroLayer : CCLayer
{
}

+(CCScene *) scene;

@end

//this is the new scene,I hope to display after the IntroLayer
@interface SecondScene : CCLayer
{
}

+(CCScene*) scene;

@end

//In IntroLayer.m
@implementation IntroLayer

//I change the replaceScene function from [HelloWorldLayer node] to[SecondScene scene]
-(void) onEnter
{
    [super onEnter];
    [[CCDirector sharedDirector] replaceScene:
     [CCTransitionFade transitionWithDuration:1.0 scene:[SecondScene scene]]];
}
@end

@implementation SecondScene

+(CCScene*)scene
{
    CCScene *scene = [CCScene node];
    SecondScene *layer = [SecondScene node];
    [scene addChild:layer];
    return scene;
}

-(id)init
{
    if (self = [super init]) {
        CGSize size = [[CCDirector sharedDirector] winSize];
        CCSprite *background = [CCSprite spriteWithFile:@"LOGO.png"];
        background.position = ccp(size.width/2, size.height/2);
        [self addChild: background];
    }
    return  self;
}

//I hope the main game scene display after the SecondScene
-(void)onEnter{
    [[CCDirector sharedDirector] replaceScene:
     [CCTransitionFade transitionWithDuration:1.0 scene:[HelloWorldLayer scene]]];
    [super onEnter];
}

@end

但是当我运行这段代码时，我发现它并没有像我预期的那样运行。SecondScene和HelloWorldLayer几乎同时显示，实际上屏幕上只剩下SecondScene并且HelloWorldLayer很快消失了。我真的对此感到困惑。任何人都可以提供一些建议吗？非常感谢。

如果您希望第二个转换跟随第一个，您需要覆盖该onEnterTransitionDidFinish方法：

-(void)onEnterTransitionDidFinish{
    [super onEnterTransitionDidFinish];
    [[CCDirector sharedDirector] replaceScene:
     [CCTransitionFade transitionWithDuration:1.0 scene:[HelloWorldLayer scene]]];
}
