I think this is an important feature and I would like b4i to support it. Since there are no services in ios like in android, it turns out that the application cannot work in the background at all, although ios itself supports the function of background uploading or downloading files. And now, without such basic things as downloading and uploading files, it is very difficult, since many applications are somehow connected with the internet, and it is not always possible to make the user wait, not hiding the application and not blocking the phone! I ask anyone can help to implement this function in b4i.
