I have develop a iOS today extension, it will display some icons, when these icons change, the today extension will update. when these icons not changed, the today extension should not update. But i found my today extension view always be destoried, then re-initiated by system, so when i pull down the notification bar, my today extension alwayd flash caused by reload the icons. I want know, how to make today extension view not be destoried by system, i want my extension view not refresh when the icons not changed.
Thanks for rely.
