objective c - Clearing AVPlayer Cache -

1) App storage increases each time while increasing the streaming video app memory from the server to the player. So if I look at the video 10 times, the size increases in 10times video memory, I am using the appplayer.

2) Stop streaming - Say I am starting to watch the video and close it after a few seconds. I saw that the video is still downloading the video after closing, I canceled AVAsset, approved AvPlayer and AVPlayerItem. Still it streams in the background.
