I want to do some tasks as soon as user comes online even he is in background. I am using Reachability class for checking internet. But this class is not notifying me when i am at background. I know people asked this question earlier but didn't got any solutions there. If i use beginBackgroundTaskWithExpirationHandler.
It gives me 3 to 4 min only, after that if network change i am not getting any notification. Please suggest me something.I think it is possible because native mail app work in that manner and my app support iOS7 only.
You cannot get notification form your classes while the app is in the background, you can make use of the new iOS 7 background fetching possibilities. Here is a tutorial http://www.objc.io/issue-5/multitasking.html
