有时候为了方便需要是不是需要把UIImage转换成精灵 ，而有时候又需要把精灵转换成UIImage， 有木有为这些在烦恼的，有的话顶起来

-(CCSprite *) convertImageToSprite:(UIImage *) image {

        CCTexture2D *texture = [[CCTexture2D alloc] initWithImage:image];

        CCSprite    *sprite = [CCSprite spriteWithTexture:texture];

        [texture release];

}

-(UIImage *) convertSpriteToImage:(CCSprite *)sprite {

   CGPoint p = sprite.anchorPoint;   

   [sprite setAnchorPoint:ccp(0,0)];  

   CCRenderTexture *renderer = [CCRenderTexture renderTextureWithWidth:sprite.contentSize.width height:sprite.contentSize.height];

   [renderer begin];

   [sprite visit];  

   [renderer end];   

   [sprite setAnchorPoint:p];  

   return [UIImage imageWithData:[renderer getUIImageAsDataFromBuffer:kCCImageFormatPNG]];

}
