Cocos2d 2.0黑屏ccscene

Question

我在使用Cocos2d 2.0版本时遇到了很大的麻烦

问题:在启动应用程序后，我的gamescene不会出现在屏幕上，无论我做什么，都会出现地狱般的黑屏。

下面是我的代码的延伸部分。

如果你们能帮助我，我将不胜感激！

//AppDelegate from cocos2d basic template, I change this line
[director_ pushScene:[GameScene node]];

//my GameScene class implementation
- (id)init
{
   if(self != nil)
    {
        BackgroundLayer *backgroundLayer = [BackgroundLayer node];
        [self addChild:backgroundLayer z:0];
    }

    return self;
}

//then, my BackgroundLayer class implementation
- (id)init
{
    if(self != nil)
    {
        CCSprite *backgroundImage = [CCSprite spriteWithFile:@"backgroundiPhone.png"];

        CGSize screenSize = [[CCDirector sharedDirector] winSize];
        [backgroundImage setPosition:CGPointMake(screenSize.width / 2, screenSize.height / 2)];
        //yea the image is in the project, maybe if I add some color at the sprite to be sure?

        [self addChild:backgroundImage z:0 tag:0];
    }

    return self;
}

为什么不在init方法中调用parent的init呢？将这一行添加到init方法的开头。

self = [super init];
