NSDateFormatter crashes when used from different threads

Question

We keep getting a random, weird crash with NSDateFormatter. The relevant stack trace is:

Program received signal:  “EXC_BAD_ACCESS”.
#0  0x00000         


        

Answer 1

EXCBADACCESS will occur when you use any deallocated object... Try to use NSZombie.. It is a easy way to find where the EXCBADACCESS occurs... It will specify which Method where and which object gets deallocated
