COCOS2D基础知识-COCOS2d单例和导演类

1.关于COCOS2d的单例和导演类

//1.COCOS2d的常用单例
        CCDirector *sharedDirector = [CCDirector sharedDirector];
        CCSpriteFrameCache *SpritesharedCache = [CCSpriteFrameCache sharedSpriteFrameCache];
        CCTextureCache *TextureCache = [CCTextureCache sharedTextureCache];
     //   CDAudioManager *sharedManager = [CDAudioManager sharedManager];
        
     //   SimpleAudioEngine *sharedEngine = [SimpleAudioEngine sharedEngine];
       //2.CCDirector 导演类
        //作用：访问和改变场景，访问2d的配置细节，访问视图，暂停，恢复，结束游戏，在UIKit和OPenGLEs之间转化坐标
        //1.主程序启动并显示第一个场景
        [[CCDirector sharedDirector]runWithScene:[HelloWorldLayer scene]];
        //2 讲传入场景作为当前的场景
        [[CCDirector sharedDirector]pushScene:[HelloWorldLayer scene]];
        //3 运行待运行场景中的倒数第二个场景，当前场景被释放
        [[CCDirector sharedDirector]popScene];
        //4 直接使用新的场景更换当前的场景，当前场景被释放
        [[CCDirector sharedDirector]replaceScene:[HelloWorldLayer scene]];
        //5结束当前运行中的场景
        [[CCDirector sharedDirector] end];
        //6 暂停当前的场景
        [[CCDirector sharedDirector]pause];
        //7 恢复场景的运行
        [[CCDirector sharedDirector]resume];
        //8绘制场景
     //   -(void)draw;
        //9讲UIKit坐标系中的坐标转换为OPENGL ES 坐标系中的坐标
        UITouch *myTouch = [touches angObject];
        CGPoint location = [myTouch locationInView:[myTouch view]];
        
        location = [[CCDirector sharedDirector]convertToGL:location];
