How to Load NSData into an AVPlayerItem?

问题

This is a follow-on question from my post about How to Encrypt mp3 Files in iOS.

How would I go about loading a track into an AVPlayerItem using NSData rather than a file path/URL?

Thanks

回答1:

[/*name of NSData*/ writeToFile:/*save file path*/ atomically: YES];
NSURL *filepath = [NSURL fileURLWithPath:/*save file path*/];
AVPlayerItem *player = [AVPlayerItem playerItemWithURL:filepath];

Untested, but should work.

Updating Dustin's answer for Swift 5:

var audioData: Data // some audio data
var fileURL: URL // some local path, probably appending NSTemporaryDirectory() 
try! audioData.write(to: fileURL)
let item = AVPlayerItem(url: fileURL)
