Dear Qiulang, You are right some VoIP manage the 'kill -9' like skype and other application. I asked on apple developer forum abd on apple develepor support how to do that. Unfortunately, they told me they don't comment the solution used by other applications. Maybe they catch some message of launchd. If you resolve the issue, I m interested by your solution.

If iOS fresh starts skype, it will show default.png as well as it's logo png, but when skype is in background, killed by ios and you click it to start it again, it only show default.png. So I think skype must be able to tell the difference between these 2 kills and do some extra work for the latter one.
