Upload images on background mode

I have web service which i want to use to upload image to the server, web service proxy classes generated by wsdl2objc it uses NSOperation to perform soap calls. Suppose during the upload process i press the home button and application enters the background mode, what will be in that case? will the upload process terminate? or process will complete anyway.

By default, the OS will freeze your app in the background. When that happens, the remote server will probably close the connection after a while because your app doesn't respond.

You can avoid that by wrapping your upload code in a background task (with the methods beginBackgroundTaskWithExpirationHandler: and endBackgroundTask:), in which case the OS will let your app run in the background for another 10 minutes to finish its work.
