如何调试EXC_CRASH（SIGTRAP）

我运行我的应用程序运行良好，直到我从后台恢复或与位置服务出，应用程序将崩溃。如何调试EXC_CRASH（SIGTRAP）

崩溃日志显示异常类型：EXC_CRASH（SIGTRAP）

任何人都知道如何调试呢？

我想你需要象征这一行：1 FrogFinder 0x000b5034 0x69000 + 311348获取崩溃方法的名称。你可以在这里找到关于象征性的信息：http://stackoverflow.com/questions/1460892/symbolicating-iphone-app-crash-reports – Johnmph 2011-12-22 00:23:04

你有没有发现是什么导致了这次崩溃？ – jasongregori 2013-01-21 21:39:12

你解决了这个问题吗？如果是这样，我很想听听是什么导致了这个问题。这是一个不寻常的错误。 – SAHM 2013-11-04 23:08:07

您也可以打开异常断点。在XCode 4中点击您的项目并选择断点标签。在该选项卡的底部是| + | - |搜索栏。选择+项目和“添加Exeception断点”。您可以将其保留在全部或选择Objective-C。这样你就可以在调试器中破解并能够看到是什么造成了这种怀疑。

使用Xcode 4.2和iOS 5未捕获的异常似乎不再显示在控制台中。我建议添加以下内容或修改现有的未捕获异常处理程序，以便为您转储异常callstack。

#ifdef DEBUG 
void eHandler(NSException *); 

void eHandler(NSException *exception) { 
    NSLog(@"%@", exception); 
    NSLog(@"%@", [exception callStackSymbols]); 
} 
#endif 

int main(int argc, char *argv[]) { 

#ifdef DEBUG 
    NSSetUncaughtExceptionHandler(&eHandler); 
#endif 

...rest of your main function here... 

}
