问题
I'm using AVPlayer to play streaming video. When Wifi drops and later enables, I see that AVPlayer cannot resume, no matter how many times I call AVPlayer play, and its currentItem 's duration is NaN, seekableTimeRanges is empty.
This is not the case for iOS 7, it resumes and plays well. The workaround I can think of is to restart the player.
How to deal with this?
