粒子动画，cocos2d 警告/错误
我是 Objective C 世界的新手，并且刚刚熟悉 cocos2d 框架。我正在尝试构建一个基本的 touchEnabled 粒子动画应用程序，该应用程序调用子类 ccParticleMeteor。我在 .m 中收到以下编译器错误/警告，并且无法重新配置我的代码以消除这些编译器错误。如果需要任何其他说明，请告诉我...谢谢！

I am new to the objective c world and have been freshly acquainted with the cocos2d framework. I am trying to build a basic touchEnabled particle animation application that calls the subclass ccParticleMeteor. I am receiving the following compiler error/warnings in my .m and I am unable to reconfigure my code to eliminate these compiler errors. Let me know if any other clarification is needed...Thanks!

这告诉您方法签名不匹配。在这种情况下，它应该是：
换句话说，“touches”方法不返回 BOOL。
This tells you that the method signatures don't match. In this case, it should be:
In other words, the "touches" methods don't return BOOL.
