Background Upload With Stream Request Using NSUrlSession in iOS8

Question

Previously in iOS7 when we try to upload with stream request in background we get following exception

Terminating app due to uncaught exception \'NSGenericEx

Answer 1

You can't upload streamed tasks using Background Configuration. I successfully upload data only in two cases:

1. Download task with data stored in request body.
2. Upload task from file. In that case you will not receive response body.

Answer 2

You can upload a multipart file in background - just that this is not straight forward. Refer: AFNetworking error in uploadTaskWithStreamedRequest
