只需在XCode断点设置中添加异常断点即可。你可能会在代码中得到异常的地方。而且，你是否有机器代码并且能够调试？如果没有，请按照这些链接 http://*.com/questions/1460892/symbolicating-iphone-app-crash-rep –

@Gagan_iOS对不起Gagan，我是iOS开发新手。我可以知道我应该在代码中添加异常断点吗？ –

请点击此链接https://*.com/questions/17802662/exception-breakpoint-in-xcode –

答

可以在调试器控制台使用“PO”命令或要么你可以在XCode中断点设置部分添加例外破发点。
