I have been trying to figure this out for days and can't figure it out. I originally thought it was my launch screen, but everything is set up fine. My app keeps getting rejected for the same reason and I need help. See the lastExceptionBacktrace from the log Apple sent me below. "exception" : {"codes":"0x0000000000000000, 0x0000000000000000","rawCodes":[0,0],"type":"EXC_CRASH","signal":"SIGABRT"}, "asi" : {"libsystem_c.dylib":["abort() called"]}, "lastExceptionBacktrace" : [{"imageOffset":40340,"symbol":"__exceptionPreprocess","symbolLocation":164,"imageIndex":6},{"imageOffset":99280,"symbol":"objc_exception_throw","symbolLocation":60,"imageIndex":15},{"imageOffset":1535240,"symbol":"-[NSException init]","symbolLocation":0,"imageIndex":6},{"imageOffset":9072980,"imageIndex":0},{"imageOffset":9073352,"imageIndex":0},{"imageOffset":8992,"symbol":"_dispatch_call_block_and_release","symbolLocation":32,"imageIndex":16},{"imageOffset":16044,"symbol":"_dispatch_client_callout","symbolLocation":20,"imageIndex":16},{"imageOffset":28556,"symbol":"_dispatch_queue_override_invoke","symbolLocation":788,"imageIndex":16},{"imageOffset":88388,"symbol":"_dispatch_root_queue_drain","symbolLocation":396,"imageIndex":16},{"imageOffset":90456,"symbol":"_dispatch_worker_thread2","symbolLocation":164,"imageIndex":16},{"imageOffset":3488,"symbol":"_pthread_wqthread","symbolLocation":228,"imageIndex":10},{"imageOffset":2940,"symbol":"start_wqthread","symbolLocation":8,"imageIndex":10}]
