I have an application, it will make a reminder to user in specific time. Now, I want to synchronize data from server every 60 minutes (or other duration:1 day, 1 week,... in the future). It must be run even app is already turned off.
I also heard a lot of different answers, but most of them is "iOS does not allow developer makes background thread". Can someone help me to confirm this?
If we can not make background thread, does it have any other solutions to resolve the problem?
I am looking forward to hearing any answers from anyone!
Thanks, Ryan
