I have tried to download some videos in ItunesU, as the files are so big that I want to cancel the download process. But it seems that there are no buttons or other ways to delete the downloading job. Searched with google, there was no good answer.
Tried a lot, at last, I got the right way:-)
In fact it’s very simple.
Slide with your finger on the downloading item from right to left, a button will be there to let you to stop and delete the downloading file. Just as delete a downloaded file.
