Will iOS launch my app into the background if it was force-quit by the user?

by

I am triggering a background fetch by using the content-available flag on a push notification. I have the fetch and remote-notification UIBackgroundModes enabled.

Here is the implementation I am using in my AppDelegate.m:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
    NSLog(@"Remote Notification Recieved");
    UILocalNotification *notification = [[UILocalNotification alloc] init];
    notification.alertBody =  @"Looks like i got a notification - fetch thingy";
    [application presentLocalNotificationNow:notification];
    completionHandler(UIBackgroundFetchResultNewData);

}

When the app is running in the background, it works fine. (The notification is received and the app triggered the “looks like i got a notification” local notification, as the code above should do).

However, when the app is not running and a push notification is received with the content-available flag, the app is not launched and the didRecieveRemoteNotification delegate method is never called.

The WWDC Video Whats New With Multitasking (#204 from WWDC 2013) shows this: enter image description here

It says that the application is “launched into background” when a push notification is received with the content-available flag.

Why is my app not launching into the background?

So the real question is:

Will iOS perform background tasks after the user has force-quit the app?
