Ios Cocos2d 2.0 SimpleAudioEngine在另一个对象中的停止声音效果

我正在尝试使用CoCoS2D2.0中的simpleaudioengine停止音频效果

我有以下情况,

农场场景，白天/晚上有两个天空层。这些是放置在场景层中创建的精灵。 我还为其他角色设置了精灵类（使用Ray Wenderlichs太空海盗代码）

当我触摸天空时，白天变为夜晚，反之亦然，我可以在农场层使用明矾ID（PollitosLayer.m）启动和停止夜晚蟋蟀的声音效果

触摸太阳精灵（类）有它自己的明矾参考，我可以开始。但我想在触摸天空精灵时阻止它

在同一个PollitosLayer.m中触摸简单的非类天空精灵时，有没有办法参考太阳类的明矾

我的代码摘录如下
