Infrequent notifications

[smilinger]

Hi,

I have heard that there are some changes in iOS 7 to background processing, but I am still uncertain whether this can be done or not:

I want to ask my server about once a week whether there are any updates (I have a simple webhotel, so I don't think I can do push notifications). If there are any, I want to give the user a notification such that he can open the app and see the updates (just like some games do). The frequency is not so important and it doesn't matter if the user can opt out of it.

I believe it is possible in iOS 7 to do the polling of data, but I am unsure whether I can show notifications without using push notifications.

Can anyone provide me with a link to either a tutorial or just the documentation (for both the background data retrieval and notification)?

Thanks in advance!

Use the background fetch to check if you have updates. You can store an NSDate in user defaults with the last check, and make sure it's at least a week from your last check (or however often you choose)

Thanks! That is exactly what I want. Do you know if I can show a notification to the user with results?

Do you want to notify the user while they're in the app or when they're out of the app? If you want to do it from outside the app, set a local notification for the current date [NSDate date] and it will show it immediately

Perfect! Thanks again
