Using iOS7 Background Fetch to ping the server

I want to use iOS7's Background Fetch functionality in order to ping the server once a day. I don't want to pull any new data - but I just want to know the app is still installed on the phone.

I can enable Background Fetch, set a Minimum Background Fetch Interval of 24 hours and always return UIBackgroundFetchResultNoData to the completionHandler.

I don't need it to be at an exact time each day. Once a day is more than enough.

Will Apple approve my app on the App Store? Can I rely on the iOS to wake my app at least once a day and perform this action? I'm afraid that if the answer will always be UIBackgroundFetchResultNoData iOS will stop waking my app.

Looks like Background Fetch and Remote Notifications WILL NOT work if your app was killed by the user.

According to the UIApplicationDelegate Protocol Reference:

However, the system does not automatically launch your app if the user has force-quit it. In that situation, the user must relaunch your app or restart the device before the system attempts to launch your app automatically again.
