OS X上的CCRenderTexture和线程警告

我在OS X上使用Cocos2D 2.0收到此警告:

- [CCRenderTexture initWithWidth:height:pixelFormat:depthStencilFormat:]:cocos2d:警告。 CCRenderTexture在自己的线程上运行。确保在此线程上使用OpenGL上下文!

以下是我认为导致警告的代码:

- (id) initWithObject: (CCNode *) object mask: (CCSprite *) mask {
    NSAssert(object != nil, @"Invalid sprite for object");
    NSAssert(mask != nil, @"Invalid sprite for mask");

    if((self = [super init])) {

        _objectSprite = object;

        _maskSprite = mask;

        // Set up the burn sprite that will "knock out" parts of the darkness layer depending on the alpha value of the pixels in the image.
        [_maskSprite setBlendFunc: (ccBlendFunc) { GL_ZERO, GL_ONE_MINUS_SRC_ALPHA }];

        // Get window size, we want masking over entire screen don't we?
        CGSize size = [[CCDirector sharedDirector] winSize];

        // Create point with middle of screen
        CGPoint screenMid = ccp(size.width * 0.5f, size.height * 0.5f);

        // Create the rendureTextures for the mask
        _masked = [CCRenderTexture renderTextureWithWidth: size.width height: size.height];

        [[_masked sprite] setBlendFunc: (ccBlendFunc) { GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA }];

        // Set render textures at middle of screen
        _masked.position = screenMid;

        // Add the masked object to the screen
        [self addChild: _masked];

        [[CCDirector sharedDirector] setAlphaBlending:YES];
    }

    return self;
}

请帮助,我只是想不出来。

ccConfig.h中,找到一行

#define CC_DIRECTOR_MAC_THREAD CC_MAC_USE_DISPLAY_LINK_THREAD

这是定义线程使用的地方。您可以尝试使用主线程选项(CC_MAC_USE_MAIN_THREAD),或使用GCD确保所有代码都在-[CCDirector runningThread]上实际执行。这几乎可以解决它。
