Loading Music Files from URLs

[ialgahmi]

How can you load the music files from URLs instead of having the file locally? Can it be done using the .plist file?

Yes it can be done but you need add a new key into .plist file and put your external URL there then modify "setCurrentAudioPath" function accordingly and change code accordingly. Replace "prepareAudio" function with following. This is a working code with a sample .mp3 on external URL.

func prepareAudio(){
    setCurrentAudioPath()
    //keep alive audio at background
    AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
    AVAudioSession.sharedInstance().setActive(true, error: nil)
    UIApplication.sharedApplication().beginReceivingRemoteControlEvents()
    let url = NSURL(string: "http://www.zero-project.gr/singles/pandoras_dream/mp3s/zero-project%20-%2001%20-%20Pandora's%20dream.mp3")
    var data = NSData(contentsOfURL: url)
    audioPlayer = AVAudioPlayer(data: data, error: nil)
    //audioPlayer = AVAudioPlayer(contentsOfURL: currentAudioPath, error: nil)
    audioPlayer.delegate = self
    audioLength = audioPlayer.duration
    playerProgressSlider.maximumValue = CFloat(audioPlayer.duration)
    playerProgressSlider.minimumValue = 0.0
    playerProgressSlider.value = 0.0
    audioPlayer.prepareToPlay()
    showTotalSongLength()
    updateLabels()
    progressTimerLabel.text = "00:00"
}

Also, how can you show the audio information, such as the title, album, and artist, on the lock screen or control center and be able to pause/play and skip audio from there?

Its working Fine in Swift 3 - you can use below method for Swift 3

func prepareAudio(){
setCurrentAudioPath()
//keep alive audio at background
try! AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, with: [])
try! AVAudioSession.sharedInstance().setActive(true)
UIApplication.shared.beginReceivingRemoteControlEvents()
let url = NSURL(string: currentAudio)
let data = NSData.init(contentsOf: url! as URL)
do {
audioPlayer = try AVAudioPlayer(data: data! as Data)
}
catch{
print(error)
}

    audioPlayer.delegate = self
    audioLength = audioPlayer.duration
    playerProgressSlider.maximumValue = CFloat(audioPlayer.duration)
    playerProgressSlider.minimumValue = 0.0
    playerProgressSlider.value = 0.0
    audioPlayer.prepareToPlay()
    showTotalSongLength()
    updateLabels()
    progressTimerLabel.text = "00:00"
}
