iPhone image upload in background

Question

I'm writing an app with an image upload feature. Right now I'm using NSURL POST like: 125306.

When the app is closed as far as I can tell all of the uploads abort and the threads die. Is there

1) a way to make these upload threads persist when the app is no longer in the foreground?

2) an iPhone OS service that will accept requests to queue a job and run it in a mode managed by the OS?

Answer 1

EDIT: This is an old answer from 2009. Current iOS (2016) has background URL tasks. See NSURLSessionUploadTask.

Original answer follows:

You aren't allowed to run in the background on an iPhone (as per Apple's Guidelines). Your app will be rejected from the AppStore if you do.

Answer 2

As has been failry well documented, no background processes are allowed using the SDK.
