Continue the task in the background.

I missed something with the multitasking function. I know that we can complete the task in the background, but I really need this task to continue when the application enters the background. So I need something other than starting a new task in the background. If the images are uploaded to the view and the user presses the home button so that the application goes into the background, I want the images to continue loading, and when the user activates the application again, he can see all the downloaded images. How can this be done? Many thanks.

In accordance with the specified documentation, if you use beginBackgroundTaskWithExpirationHandler:while in the foreground, it will continue to perform background viewing until it ends. Upon completion of this task, your application may be suspended.
