iOS - How to download Audio file

Question

I am currently working on an app which requires me to download audio files from web server. The URL would be something like this: http://universalstreamsolution.com/Samonas/test1.m4a .

Any suggestions on what I should do to be able to reach my goal?

Answer 1

if you need the data in the format of data, you can use the data class to download the data with the method to download the data from an URL:

[NSData dataWithContentsOfURL:URL]

also consider the answer there for playing an NSData as audio: How to play an audio if we pass NSData?

Answer 2

[NSData dataWithContentsOfURL:URL] works but it causes UI block so that user can not interact with device till the file is completely downloaded. Such a bad user experience. I suggest using NSURLSession with this great tutorial: http://www.raywenderlich.com/51127/nsurlsession-tutorial
