How to play mp3 audio from URL in ios swift

I am getting mp3 url as a response of api calling.
I want to play that audio, so how can i do that? (ios swift)

here is my response

{
content = "En este primer programa se tratar\U00e1n asuntos tan importante como este y aquel sin descuidar un poco de todo lo dem\U00e1s";
file = "http://radio.spainmedia.es/wp-content/uploads/2015/12/ogilvy.mp3";
image = "http://radio.spainmedia.es/wp-content/uploads/2015/12/tapas.jpg";
number = 0001;
subtitle = Titulareando;
title = "Tapa 1";
}


here is my code::

@IBAction func btnplayaudio(sender: AnyObject) {
let urlstring = "http://radio.spainmedia.es/wp-content/uploads/2015/12/tailtoddle_lo4.mp3"
let url = NSURL(string: urlstring)
print("the url = \(url!)")

play(url!)

}

func play(url:NSURL) {
print("playing \(url)")

do {
self.player = try AVAudioPlayer(contentsOfURL: url)
player.prepareToPlay()
player.volume = 1.0
player.play()
} catch let error as NSError {
self.player = nil
print(error.localizedDescription)
} catch {
print("AVAudioPlayer init failed")
}

}


where am i going wrong?

Answer Source

I tried the following,

    let urlstring = "http://radio.spainmedia.es/wp-content/uploads/2015/12/tailtoddle_lo4.mp3"
    let url = NSURL(string: urlstring)
    print("the url = \(url!)")
    downloadFileFromURL(url!)

Add the below methods,

func downloadFileFromURL(url:NSURL){
    var downloadTask:NSURLSessionDownloadTask
    downloadTask = NSURLSession.sharedSession().downloadTaskWithURL(url, completionHandler: { (URL, response, error) -> Void in

        self.play(URL!)

    })

    downloadTask.resume()

}

And your play method as it is,

func play(url:NSURL) {
    print("playing \(url)")

    do {
        self.player = try AVAudioPlayer(contentsOfURL: url)
        player.prepareToPlay()
        player.volume = 1.0
        player.play()
    } catch let error as NSError {
        //self.player = nil
        print(error.localizedDescription)
    } catch {
        print("AVAudioPlayer init failed")
    }

}

Download the mp3 file and then try to play it, somehow AVAudioPlayer does not download your mp3 file for you. I am able to download the audio file and player plays it.

Remember to add this in your info.plist since you are loading from a http source and you need the below to be set for iOS 9+
