App crash report in device logs

Question

I'm facing a problem with a crash after testing my application for more than 20 minutes. It is crashing somewhere but I'm not able to find where it is crashing. I enabled NSZombiaEnable but still, I don't get any correct report.

Below is my device crash log:

Please help me.

Answer 1

because it isnt a bad access, there wont be a zombie... its segfaulting.

cause #1:
bad format in an NSLog or stringWithFormat :D (at least for me)

cause #2: if that's not it try looking for c-code you use that may not exist.

(non-existing symbols)

top hint: cause #3:
the IOS filesystem is case sensitive, maybe the xib name you specify is somehow wrong and it cant load the xib? / a xib itself is corrupt

cause #4:
google for "Assuming job exited: : 10: No child processes" :D
