来自 Apple 评论的符号化 iOS 崩溃报告仍不可读

Question

I got a crash report from Apple and symbolicated it following this document , but I still didn't understand the report.

First, I tried below "XCode approach" to symbolicate the report:

1. Connect an iOS device to your Mac
   
2. Choose "Devices" from the "Window" menu
   
3. Under the "DEVICES" section in the left column, choose a device
   
4. Click the "View Device Logs" button under the "Device Information" section on the right hand panel
5. Drag your crash report onto the left column of the presented panel
6. Xcode will automatically symbolicate the crash report and display the results

Before that, I downloaded dSYM files from App Store by 'Organizer' and copied them into a separated folder. But all the symbolicated names looked like this:

5   Recycling                       0x10103b464 fb1UCM8vZCiE + 355
6   Recycling                       0x1010431d4 fbkUVUzGnhkS + 1655
7   Recycling                       0x101038a78 fbIiaWxkoUb6 + 307

And then, I tried the approach from this blog , but the problem remained:

Can anyone help me?

Answer 1

In Xcode 10 you can follow these steps:

Inside Organizer, locate the archive where the app is based on. Click on the Download Debug Symbols button. Nothing will appear in your Downloads folder, but that's OK. Connect the build machine to an iOS device. Select the device in Devices and Simulators. Click on the View Devices Logs button. Drag-and-drop the crash file to the left panel. The file must end with a .crash extension, otherwise the drag fails. Switch to the All Logs tab. Select the added crash file. The file should automatically symbolicate, otherwise use the right-click context menu item Re-Symbolicate Log.

Answer 2

Thanks for everyone! I finally resolved this problem by myself.

The reason is that I used a 3rd-party library named UMCCommon with version 1.5.3 , and all of its symbols are obfuscated , so I can not understand.
