How to keep my app longer than 10 min. in the background?

Question

I know that in iOS, background apps can only be running

• Finite-length tasks (10 min)
• Location updates
• VoIP
• Audio

Is there a way for my application to avoid being terminated after being 10 min. in the background? I will not be submitting my app to the app store, so everything is allowed (private frameworks, using the gps even if I don't need it) I know apple does not recommend this, but it is just for monitoring purposes. I need it to be running without a limit.

I explored several possibilities including the VoIP , but it only gives me 30 seconds every 10 minutes, which is not enough. I also read this post: iPhone - Backgrounding to poll for events in which JackPearse specified a way to "revive" the 10 minute finite-length task using the VoIP 30 second task. But I don't want my task to start and end every 10 minutes, it must run continuosly. I also tried his UPDATE2, but it's not working for me. I even tried intercepting the UIEvent with GSEvent.type 2012, which seemed to be the one ending my background task, but no luck. Strangely, my background task is never ended when I have Xcode opened and debugging, but when I don't (test the simulator alone) it ends after 10 minutes.

Answer 1

I have already tried some way(nsrunloop,*performselectoronmainthread*) like that.It's works well in simulator (not in device because apple crashes automatically after sometimes) when the app goes to background.

status is a BOOL variable.

- (void)applicationDidEnterBackground:(UIApplication *)application {

    while (!**status**) {
        [[NSRunLoop mainRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:60.0]];
        [self goBackground];
    }
}
