Iphone 用于加载cocos2d场景的白色屏幕

我是cocos 2d游戏开发新手，正在开发一款需要多次从view controller重新加载场景的游戏。为此，我删除了场景并再次运行。在加载场景2次或更多次后，出现了白屏，并且在控制台中显示错误“OpenGL错误0x0506 in-[EAGLView swapBuffers]”

下面是我添加场景的代码-

             if ([[CCDirector sharedDirector] runningScene] == NULL) 
             {
    if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )
        [CCDirector setDirectorType:kCCDirectorTypeDefault];

    CCDirector *director = [CCDirector sharedDirector];

    glView = [EAGLView viewWithFrame:[window bounds]
                                   pixelFormat:kEAGLColorFormatRGBA8
                                   depthFormat:GL_DEPTH_COMPONENT24_OES
                            preserveBackbuffer:NO
                                    sharegroup:nil
                                 multiSampling:YES
                               numberOfSamples:4];




    [director setOpenGLView:glView];        
    [director setDeviceOrientation:kCCDeviceOrientationPortrait];   
    [director setAnimationInterval:1.0/60];
    [window addSubview:glView];     

    [[CCDirector sharedDirector] runWithScene: [HelloWorldLayer node]];

[[CCDirector sharedDirector].openGLView removeFromSuperview];
[[CCDirector sharedDirector] stopAnimation];
[[CCDirector sharedDirector] end];
[[CCDirector sharedDirector] release];

}

和用于删除场景的代码-

             if ([[CCDirector sharedDirector] runningScene] == NULL) 
             {
    if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )
        [CCDirector setDirectorType:kCCDirectorTypeDefault];

    CCDirector *director = [CCDirector sharedDirector];

    glView = [EAGLView viewWithFrame:[window bounds]
                                   pixelFormat:kEAGLColorFormatRGBA8
                                   depthFormat:GL_DEPTH_COMPONENT24_OES
                            preserveBackbuffer:NO
                                    sharegroup:nil
                                 multiSampling:YES
                               numberOfSamples:4];




    [director setOpenGLView:glView];        
    [director setDeviceOrientation:kCCDeviceOrientationPortrait];   
    [director setAnimationInterval:1.0/60];
    [window addSubview:glView];     

    [[CCDirector sharedDirector] runWithScene: [HelloWorldLayer node]];

[[CCDirector sharedDirector].openGLView removeFromSuperview];
[[CCDirector sharedDirector] stopAnimation];
[[CCDirector sharedDirector] end];
[[CCDirector sharedDirector] release];

请帮帮我，我不明白问题出在哪里。 谢谢

需要注意两件事：

• 不要释放CCDirector！您所需要做的就是调用stopAnimation和稍后的startAnimation
• 不要从超级视图中删除openGLView。相反，只需隐藏它：[CCDirector sharedDirector].openGLView hidden:YES]
