Cocos2d iphone 应用程序在目标c中的NSException处崩溃

这是我的代码。在这个方法中，我的应用程序在CheckIntersectOrNot方法处崩溃。在这个方法中，它在[self-DifferentColorBalls:loBall]；行处崩溃；。在这方面，我也使用了异常，但它不起作用

请任何人帮我解决这个问题。为什么它会崩溃，并就这个问题给出任何建议

非常感谢

太多的代码，没有异常。您在控制台中看到什么异常情况？您的代码不容易阅读，我在控制台中看不到任何东西。当应用程序崩溃时，我看到程序收到信号：EXC\u BAD\u accessemm。。。你为什么认为这意味着例外？EXC_BAD_ACCESS表示您尝试使用不存在的对象非常感谢您的建议在Xcode中添加一个异常断点，让它显示导致异常的确切行。
