Launch an app with push notification after it has been terminated

I was wondering if there was a way to wake up an app that has been terminated by the user on ios8-9. By terminated I mean double click on the home button and swipe up.

Is it somehow possible to launch an app by sending a silent push notification so that didreceiveremotenotification gets fired and gives me some runtime ?

I have noticed that a fair share of my users terminate my app. As I rely heavily on background fetch, this a problem. My idea was to send silent push notifications to launch the app in the background and trigger background fetch.

Short Answer: No That is not possible.

Detail:

When there is any new content on server you will send Remote Notification to your application to inform about that. (A Remote Notification is really just a normal Push Notification with the content-available flag set)

When application received this Remote Notification it calls following method:

- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler

In Documentation of this method it is clearly written:

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.
