iOS Question Help with reading ios crashes (KSCrash)

[fastlingo]

I have received a crash log on my email. How can I find the place in the code where this crash occurred?
This is the beginning of the crash log. qx is a code module, launchmainpage is a sub in this module, but what do those numbers mean?

you still have to symbolize the crash report to find out where the error occurs:

Symbolicating a crash report

I will cover the steps required to symbolicate a crash report received from Apple. The result is a readable stack trace. It requires a local Mac. The crash report is a text file that looks like: 1. Find the binary address: 2. Unzip the Archive.zip (the one used when uploading the app)...
