I want to download data when receiving a push notification while the app is not active.

I enabled push notifications in background mode.

This is my code :

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    println("App is alive !!!")
    downloadData(){
        (success:Bool) -> Void in
        println("data downloaded : \(success)")
        var result = success ? UIBackgroundFetchResult.NewData : UIBackgroundFetchResult.Failed
        completionHandler(result)
    }
}

I launch the app in debug mode, I leave it. I receive a push notification. The data is not downloaded.

I don't even know if the the didReceiveRemoteNotification has been called.

What am I doing wrong ?

Have you implemented the backgroundhandler/expirationhandler for the event? – Akhilesh Sharma Sep 24 '15 at 17:05
I don't know about this. Could you explain it ? – Cherif Sep 24 '15 at 17:07

_I don't even know if the the `didReceiveRemoteNotification` has been called._ What about this line: `println("App is alive !!!")`? Does it get printed or not? First make sure, if your callback is called or not. – Baris Akar Sep 25 '15 at 09:32
Nothing prints on the console – Cherif Sep 25 '15 at 10:40
