Does someone has experience/alive sample with NSURLSession in background ?
I need to upload groups of files (approx. 100-200 Mb) and to receive a comfirmation from server. Each file has separate parameters in URL and I need to correct header also.
I used a service in In Android and sent file by file (this works even if app is not started). In IOS I did something similar by timer, but this does not work in background mode and sometimes there are troubles, because users like to close an app.
