用cocos2.0中的什麼替換openGLView來清除背景顏色？

Question

在1.0中，我們使用以下代碼將CCDirector OPENGLView設置爲透明。

director.openGLView.backgroundColor = [UIColor clearColor]; 
director.openGLView.opaque = NO; 
glClearColor(0.0, 0.0, 0.0, 0.0); 

在2.0中，我們該怎麼辦？我使用以下，它不起作用，背景顏色仍然是黑色。

director.view.backgroundColor = [UIColor clearColor]; 
director.view.opaque = NO; 
glClearColor(0.0, 0.0, 0.0, 0.0); 

整個代碼如下：本

#import "cocos2d.h" 

#import "AppDelegate.h" 
#import "IntroLayer.h" 
#import "HelloWorldLayer.h" 

@implementation AppController 

@synthesize window=window_, navController=navController_, director=director_;

{ 
    // 
    // THIS CODE REMOVES THE STARTUP FLICKER 
    // 
    // Uncomment the following code if you Application only supports landscape mode 
    // 
#if GAME_AUTOROTATION == kGameAutorotationUIViewController 

    // CC_ENABLE_DEFAULT_GL_STATES(); 
    // CCDirector *director = [CCDirector sharedDirector]; 
    // CGSize size = [director winSize]; 
    // CCSprite *sprite = [CCSprite spriteWithFile:@"Default.png"]; 
    // sprite.position = ccp(size.width/2, size.height/2); 
    // sprite.rotation = -90; 
    // [sprite visit]; 
    // [[director openGLView] swapBuffers]; 
    // CC_ENABLE_DEFAULT_GL_STATES(); 

#endif // GAME_AUTOROTATION == kGameAutorotationUIViewController

調試了幾天，不知道爲什麼。 返回使用框架v1，沒有這個問題，
