来自spritesheet和着色器的Cocos 2d Iphone v3 Sprite

Question

搜索stackoverflow并且Google没有返回任何结果。

 [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"sun.plist"];
 CCSprite* sprite = [CCSprite spriteWithImageNamed:@"8.jpg" ];
 sprite.position = ccp(self.contentSize.width/2 + 300, self.contentSize.height/2);
 [self addChild: sprite];

显示屏显示plist

中选定的精灵

但如果我应用着色器程序，则精灵重叠

解决方案是什么？ 没有着色器：

重叠：
