backtrace still not readable after symbolicating iPad crash log

问题

i have these crash logs and after i drop them in the organizer the get symbolicated automatically but the result is always the same. the iOS calls get symbolicated and my app calls don't.

I tried copying the dysm and app file into the same folder, deleting and copying back again. nothing helped.

Any idea whats going on ? So I am getting something like this:

you can see that the UIKit functions got symbolicated but not MyApp

回答1:

You need the dSYM file and the app binary of the exact build that generated the crash report. Usually you get this result in Xcode if the dSYM wasn't found using the symbolication script via spotlight. If this is from a debug build, and you created a new build in the meantime, you are out of luck. Otherwise make sure the directory where the debug build is stored to, is indexed by Spotlight. If this is from a build that is archived, make sure the archived directory is indexed by Spotlight.

The crash report contains a section title "Binary Images", and on the top of that your app binary is referenced with the binaries UUID. It looks like c42a118d722d2625f2357463535854fd, which needs to be changed to uppercase and the format 8-4-4-4-12 and will then look like this: C42A118D-722D-2625-F235-7463535854FD.

You can use that to search the dSYM via spotlight in a terminal via:

mdfind "com_apple_xcode_dsym_uuids == C42A118D-722D-2625-F235-7463535854FD"
