IOS Crash positioning

I use Symbolicatecrash to do crash file symbols when found that no effect, try to use Atos for crash file to sign. Special record use process.

Documents Required for Prerequisites:

The Appname.app.dSYM is in the package that was packaged in Xcode archive.

1, search the Xx.crash file in the last Exception backtrace: Find the project corresponding record

You can see two addresses at this point:

0x0000000101250000  is the loading address of the module
0x0000000101488a10  is the address where crash occurs

2. Use Atos to sign

Atos Command format

Atos [-O appname.app/appname] [-l loadaddress] [-arch architecture]

To use the command:

$ xcrun atos-arch arm64-o./appname.app.dsym/contents/resources/dwarf/appname-l 0x0000000101250000  0x0000000101488a10

Or

$ xcrun atos-arch arm64-o/xx-l 0x0000000101250000  0x0000000101488a10

Annotations:

1, arm64 is the type of architecture: arm64, ARMv7
2, the above XX and Appname.app.dsym/contents/resources/dwarf/appname is the same file, but manually copied out

Tip If you can't use armv7, try using arm64
