如何从Apple读取此崩溃日志

Question

I just had my app reviewed by Apple and it apparently crashed, which I cannot reproduce (same device and iOS version).

The app crashed when they clicked on a button which 1. Shows a new view with a modal segue 2. Accesses address book

I've been looking at the two crashlogs they sent me but I'm stuck, while it doesn't look very complicated.

Could you help me and guide me through it?

Thanks a lot!

I renamed my app MyGreatApp in the log, and just pasted the part about the thread that crashed, if you need anything else, please ask !

Edit: I symbolicated the log thanks to @Larme , pretty self explanatory now :)

So does this mean it could not instantiate the view from storyboard? the obj_exception throw means that the controller does not exist? Because it works fine on my device…

Answer 1

After symbolicating the crashlog (thanks @Larme) it became obvious that I was trying to instantiate a view controller from storyboard with an identifier that didn't exist! Just had to go in storyboard and put the right identifier on the view controller.
