取得mp3作为NSData

Question

I want to play a mp3 from my server with AVAudioPlayer. I am trying to do it by using

initWithData:(NSData *) error:(NSError **)

To do this I need to convert the mp3 to NSData then pass the NSData into my player. How do I convert the mp3 to NSData.

Answer 1

NSData has an - initWithContentsOfURL : (or + dataWithContentsOfURL :) method you could use.

Or, you could use NSURLConnection to download your MP3 as NSData .

I'd advise the second method, because it can be used asynchronously and doesn't block the main thread, unlike NSData 's - initWithContentsOfURL :

Answer 2

When you download it from the server, conveniently, you already have an NSData object. Did you try starting the player with that?
