How to cache audio

• I'm using NSCache to cache every loading AVPlayerItem, with key is audioLink
• Using only one instance of AVPlayer to plays all audios in app, avoid create too many players it leading to crash
• When playing an audio, just checking it whether in cache or not.
  • If cache already had that audio the get corresponding AVPlayerItem and replace to the player.
  • If cache not contains that audio then create new AVPlayerItem, replace into the player and add it into cache
