It is okay if I run app on ios 7 and 8. When I run on ios 6, I got these error in my device log.
Job appears to have crashed: Segmentation fault: 11
Application 'UIKitApplication:com.myapp.app[0x6f3e]' exited abnormally with signal 11: Segmentation fault: 11
libMobileGestalt copySystemVersionDictionaryValue: Could not lookup ReleaseType from system version dictionary
I have searched through but it doesn't solve. May I know how to do?
Segmentation faults are usually caused by (way) over-allocating memory. The other warnings you posted seem to support this. Does your app maybe contain a loop where it creates lots of objects without freeing them. So free the memory allocated....
