Q: Apps still function, after killing them off?

My expectation is that if I kill an App, that it's stopped.  But I've found that some continue to have activity afterward, unless I reboot the phone.

 

This applies to iOS 6.1. 

 

This doesn't make a lot of sense to me, so I wonder if someone can elaborate what's going on here - or whether there is some other way to handle it.

iPhone 4S, iOS 5.1.1, iOS 6

A:

Apple Push Notification Service (APNS) notifications do not originate with the app itself. APNS notifications are submitted by the app developer's server infrastructure to Apple's APNS infrastructure. The APNS infrastructure then sends the notification to your iPhone. If your app is not active, iOS shows the notification message, not the app. If you respond affirmatively to the notification message, the app will then resume if suspended, start if terminated.

 

All apps that use APNS notifications work like this.

 

As several posters pointed out, you can control whether/how the notification message appears by twiddling the appropriate notification settings.

    Push notifications are controlled entirely in the notifications section of the phone settings.  They are "pushed" to the phone from an external server as a message that's linked to the app. The app isn't running. In fact, push notifications existed before iOS had any multitasking capability.

    Thanks everyone for the clarification.  Now I  understand what's happening.

     

    I had assumed if I kill the App, that all activity would stop -- and I think that's not wrong to expect. 

     

    What I have seen is the notifications will come in after the App is killed -- unless I reboot the phone.  That is, the notifications are still enabled for the App (ie: show text when a message comes in) and I do not get those notifications until I start the App up again.  


    So reboot it is :-)
