crash-reports - atos表示崩溃的错误原因

Question

在我当前的项目中，我可能会由于内存过冲而导致随机崩溃。但是我实际上想弄清楚是哪个类导致了崩溃。因此，我使用了符号化方法来查找崩溃的原因。
这是我所做的:

首先，XCode Build设置如下所示:

复制期间剥离调试Sysbol:否
部署后处理:是
带状连接产品:是
生成调试符号:是
调试信息格式:带有dSYM文件的DWARF
使用分隔条:是

我将iOS 5.1与4.3.2版本的XCode一起使用。我已经使用“symbolicatecrash”和“atos”方法来揭示崩溃的原因。但是我无法找到崩溃的原因。

所以我尝试了这个。我自己通过访问数组的超出范围的索引使应用程序崩溃。我用它来验证我的实际崩溃的符号化崩溃结果输出。

这是崩溃报告的输出:

一长串二进制图像

现在，当我使用“atos”从线程0(导致崩溃)中获取崩溃原因时

3   MyAppName                           0x00104aa0 0x5e000 + 682656

使用上面的地址，它给我这个输出:

MAC66:Resources sourabhbhardwaj$ atos -arch arm -o /Users/myPath/MyAppName.app.dSYM/Contents/Resources/DWARF/MyAppName 0x00079f6c 0x78000 + 8044
-[FirstViewController setUIAndText] (in MyAppName) (FirstViewController.m:85)
-[SecondViewController DeleteByID:] (in MyAppName) (SecondViewController.m:415)
+
-[MyController viewWillAppear:] (in MyAppName) (MyController.m:137)

这不是我所做的实际崩溃行。我在其他 View Controller 上崩溃了，输出完全不同。这怎么可能？
是的，我已经交叉检查了我是否对该二进制文件使用了完全相同的dSYM文件。

需要快速帮助。

谢谢

Answer 1

在符号化之前，请确保您具有已崩溃的内部版本的.app和.dSYM相同，否则将无法正确地对其进行符号化。
