I am new to NSURLSession and specially background download tasks. Is there a way to query NSURLSession to return a list of background tasks? It seems possible to make duplicate requests for background download tasks. I do not get any error if I make the same url download request while a previous one is still in progress.
What is the best way to handle this situation? I can maintain a list of urls I am currently downloading from, but in case the app is relaunched I lose this reference. I can again store this information in persistent storage. But it just seems inconvenient not to have an option to query NSURLSession for this.
