ios - How to pass data from containing app to widget in today view? -


i wrote widget app, , according articles, used "app group" bridge pass data containing app widget app, there not images , words info, frame/layout info in data.

the problem found widget view not shown immediately, may existed 1~3 seconds delay. what's worse, widget view showed "unable download" if data included many info(i need show many things in widget).

after long attempt, still not found real reason caused issues. guess "app group" may not work well, can me figure out what's wrong work?
