Well, I have to say your reply really does not make sense to me. In your last reply, you said "the app will be automatically restarted after killed by system". This time you said "you can add capturing uncaught exception in your app", you app was killed without any notice then how can you capture the uncaught exception ? I am not being rude. Just your reply does not make sense at all. On 3/14/13 2:26 PM, Pai Peng wrote: > The app does n't get any event , when it is killed by system. But you can add capturing uncaught exception in your app. In this way, the client can know why be killed and do something (write some logs) and by next start read them. > > > > > Sent from my iPhone > > On 14.03.2013, at 01:00, qiulang <qiulang at sinicnet.com.cn> wrote: > >> But how do you define "exited gracefully" ?

(One could easily write something to NSUserDefaults which says that it exited gracefully, and then clear it upon relaunch; if the flag isn't present when the app is launched it does something different upon relaunch) >>> >>> cheers, >>> - j >>> >>> _______________________________________________ >>> Visit our blog: http://blog.pjsip.org >>> >>> pjsip mailing list >>> pjsip at lists.pjsip.org >>> http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org >> >> _______________________________________________ >> Visit our blog: http://blog.pjsip.org >> >> pjsip mailing list >> pjsip at lists.pjsip.org >> http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org >
