[QUOTE="s.furlani, post: 1356665, member: 233706"] I'm new to iOs development, and I have a question about how an app can receive a push notification while it's not running in background or in foreground. I read that there's a kind of "invisible" background, where the app can receive a push notification starting from server, i think Skype or Facebook use this techinque when you receive a private message (infact you receive it also if the app is completely closed). What I want to know is if in the same way we can start a request from an app that is closed asking to a server if there are new notifications every "x" minutes in an opposite way (it's not the server that sends, but is the client that asks) My problem is that I don't want to mantain a notification server, whereas I prefer to let the app periodically run quieries to the server. Is this possible? if yes, which are the iOs supported versions? [/QUOTE]
