我有一个崩溃转储,它不会正常符号化 - 当我将其拖入Xcode组织器或手动运行symbolicatecrash时,系统符号会显示,但应用程序指令地址都不会被触及。
我尝试使用atos来解决这个问题,但我得到的结果是:
got symbolicator for myarchive.xcarchive/Products/Applications/MyApp.app/MyApp, base address 4000
___lldb_unnamed_function2115$$MyApp (in MyApp) + 992
___lldb_unnamed_function2096$$MyApp (in MyApp) + 66
___lldb_unnamed_function6053$$MyApp (in MyApp) + 348
___lldb_unnamed_function6064$$MyApp (in MyApp) + 162
___lldb_unnamed_function6002$$MyApp (in MyApp) + 18
___lldb_unnamed_function1029$$MyApp (in MyApp) + 416
___lldb_unnamed_function2280$$MyApp (in MyApp) + 106
___lldb_unnamed_function2272$$MyApp (in MyApp) + 198
___lldb_unnamed_function400$$MyApp (in MyApp) + 96
___lldb_unnamed_function1$$MyApp (in MyApp) + 36
当前映射到___lldb_unnamed_function1$$MyApp (in MyApp) + 36
的地址应该与main.m中的根调用相对应。显然,我不知道其他人应该是什么,但我猜测,如果一个人错了,他们就错了。什么可能导致这个? ___lldb_unnamed_function通常出现在嵌入块中的函数以外的任何地方吗?
不幸的是,这会产生一个很长的问题,但由于在计算应用程序二进制文件的负载偏移量时可能会出错,因此我将列出生成上述输出所遵循的步骤。
我使用dwarfdump -u myarchive.xcarchive/Products/Applications/MyApp.app/MyApp
来验证我使用的是正确的二进制文件:
UUID: BA41E9A3-4BB5-3F8A-8D57-0D16447FFEC6 (armv7) myarchive.xcarchive/Products/Applications/MyApp.app/MyApp
UUID: A6E0970C-05FE-3A79-887D-84F3892637FD (armv7s) myarchive.xcarchive/Products/Applications/MyApp.app/MyApp
崩溃转储中的UUID与第一个匹配:
Binary Images:
0x97000 - 0x3cefff +MyApp armv7 <ba41e9a34bb53f8a8d570d16447ffec6> /var/mobile/Applications/AF97EC52-7A2F-4772-AA05-74E739BA6882/MyApp.app/MyApp
此行还将负载偏移列为0x97000,架构为armv7。我感兴趣的地址是:
1 MyApp 0x001357dc 0x97000 + 649180
2 MyApp 0x00134446 0x97000 + 644166
3 MyApp 0x00240cec 0x97000 + 1744108
4 MyApp 0x002416ea 0x97000 + 1746666
5 MyApp 0x0023e2de 0x97000 + 1733342
6 MyApp 0x000de724 0x97000 + 292644
7 MyApp 0x00144f1a 0x97000 + 712474
8 MyApp 0x00144336 0x97000 + 709430
27 MyApp 0x000b1024 0x97000 + 106532
28 MyApp 0x0009d464 0x97000 + 25700
所以我跑了xcrun atos -l 0x97000 -arch armv7 -o myarchive.xcarchive/Products/Applications/MyApp.app/MyApp 0x001357dc 0x00134446 0x00240cec 0x002416ea 0x0023e2de 0x000de724 0x00144f1a 0x00144336 0x000b1024 0x0009d464
,它给了我上面的输出。
注意:由于这看起来不正确,我想也许我需要手动减去幻灯片值。我是使用xcrun otool -arch armv7 -l myarchive.xcarchive/Products/Applications/MyApp.app/MyApp

但是,使用-l 0x93000重新运行命令给了我一个非常相似的结果:

答案 0 :(得分:5)
您必须使用atos
包来调用dSYM
,而不是应用包,因为通常会删除符号!
所以电话是:
xcrun atos -l 0x97000 -arch armv7 -o myarchive.xcarchive/dSYMs/MyApp.app.dSYM 0x001357dc 0x00134446 0x00240cec 0x002416ea 0x0023e2de 0x000de724 0x00144f1a 0x00144336 0x000b1024 0x0009d464
