how can I use UIWebview as always working on background

Question

I would like to set UIWebview always running on background. UIWebview is not working when iPhone entered 'applicationDidEnterBackground'. so I want UIWebview to run always on backgroud. Is it possible?

Every app can continue to execute in the background for roughly 10 minutes before it terminates. Only certain apps can continue to execute in the background, such as audio/gps/bluetooth etc related apps. You can find out more here.

The following code sample is from the app doc and can help you get started -

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    bgTask = [application beginBackgroundTaskWithExpirationHandler:^{
        // Clean up any unfinished task business by marking where you.
        // stopped or ending the task outright.
        [application endBackgroundTask:bgTask];
        bgTask = UIBackgroundTaskInvalid;
    }];

    // Start the long-running task and return immediately.
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

        // Do the work associated with the task, preferably in chunks.

        [application endBackgroundTask:bgTask];
        bgTask = UIBackgroundTaskInvalid;
    });
}
