如何在AvAudioplayer中快速添加URL

Question

i just want to ask on how to play audio using avAudion using url link..

and im getting error bad request.. can someone help me?

i already tried using avplayer but it is not suitable for me.. though it is working but.. i kinda prefer to use avaudioplayer

    let mp3URL = NSURL(fileURLWithPath:"https://s3.amazonaws.com/kargopolov/kukushka.mp3")
    do {
        // 2
        audioPlayer = try AVAudioPlayer(contentsOf: mp3URL as URL)
        audioPlayer.play()
        // 3
        Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(updateAudioProgressView), userInfo: nil, repeats: true)
        progressView.setProgress(Float(audioPlayer.currentTime/audioPlayer.duration), animated: false)
    }
    catch {
            print("An error occurred while trying to extract audio file")
    }

Answer 1

According to the AVAudioPlayer documentation , if you want to play audio over the internet (that's not already downloaded to disk or memory) you should use AVPlayer .

The docs describe AVAudioPlayer as

An audio player that provides playback of audio data from a file or memory.

A little further down, in the overview section, emphasis added:

Use this class for audio playback unless you are playing audio captured from a network stream or require very low I/O latency.

Notes

1. You can get some more information from the runtime by accessing the error object that is thrown when the connection fails. Change catch { to catch let error { and then you can log out the error as part of your message, like so:

catch let error{
    print("An error occurred while trying to extract audio file: \(error)")
}

2. When I run your sample code in Xcode playgrounds with the change noted above, I see the following:

An error occurred while trying to extract audio file: Error Domain=NSOSStatusErrorDomain Code=2003334207 "(null)"

3. Notice the error's Domain and Code . Pasting that error into Google yields some results that indicate that the URL might not be resolving correctly. (Indeed, clicking on that mp3 link shows a bad access error message.)

The first result is another StackOverflow post with a similar issues. The second one is an Apple Developer Forum post which has some more information.

Let's try to change the URL to a publicly accessible sample mp3 file. (I found this one by searching the web for "test mp3 file" on Google.)

4. You'll want to change NSURL to URL , and instead of fileURLWithPath , you're going to want to use another initializer. (Say, string: .)

5. Whenever you see contentsOf...: in a media or file API, there's a good chance it expects data or a file, to the exclusion of a network stream. Similarly, when you see an initializer or method that takes a fileURL... , the system expects to be pointing to a local resource, not a network URL.

Answer 2

if let mp3URL = URL(string: "https://s3.amazonaws.com/kargopolov/kukushka.mp3"){
        // do s.t
}   

Anyway, you should know the basics of ios
