Question

如何将解析后的音频文件添加到AVAudioPlayer而不是AVPlayer？我希望能够暂停，播放，停止，重放和使用滑块来控制音频播放。我试过这个：

我的尝试：

var query = PFQuery(className:"Song1")
query.getObjectInBackgroundWithId("YSuNRfKq3n") {
    (object : PFObject?, error : NSError?) -> Void in
        if let AudioFileURLTemp = object?.objectForKey("SongFile")?.url {
            AudioPlayer = AVPlayer(URL: NSURL(string: AudioFileURLTemp!))
            AudioPlayer.play()
        }
    )
}

Answer 1

试试这个

var query = PFQuery(className:"Song1")
query.getObjectInBackgroundWithId("objectId") {
    (object : PFObject?, error : NSError?) -> Void in
        if let AudioFileURLTemp = object?.objectForKey("SongFile")?.url {
            AudioPlayer = AVPlayer(URL: NSURL(string: AudioFileURLTemp!))
            AudioPlayer.play()
        }
    )
}

类ViewController：UIViewController，AVAudioPlayerDelegate，AVAudioRecorderDelegate {

var goAudio = AVPlayer()
var show = AVAudioPlayer()

var soundData : NSData!

override func viewDidLoad() {
    super.viewDidLoad()
    streamShow()
}

@IBAction func playShow(sender: UIButton) {
    self.show.prepareToPlay()
    self.show.volume = 1.0
    self.show.delegate = self
    self.show.play()
}

func streamShow(){
    var query = PFQuery(className:"sveglia")
    query.getObjectInBackgroundWithId("hQHeNCqccH") {
        (object : PFObject?, error : NSError?) -> Void in
        if let AudioFileURLTemp = object?.objectForKey("audio")?.url {

            self.goAudio = AVPlayer(URL: NSURL(string: AudioFileURLTemp!))

            let fileURL = NSURL(string: AudioFileURLTemp!)
            var error: NSError?
            let data = NSData(contentsOfURL: fileURL!)
            self.show = AVAudioPlayer(data: data, error: &error)

        }
    }
}

}

使用滑块解析音频
