快速播放一系列音頻文件

Question

嗨，我想一個接一個地播放5個音頻文件。

我有一些代碼將發揮作用。

有誰知道如何一個接一個地播放一組音頻文件？

謝謝

import UIKit
import AVFoundation

class ViewController: UIViewController, AVAudioPlayerDelegate {

var audioPlayer: AVAudioPlayer?

/* The delegate message that will let us know that the player
has finished playing an audio file */
func audioPlayerDidFinishPlaying(player: AVAudioPlayer!,
    successfully flag: Bool) {
        println("Finished playing the song")


}

override func viewDidLoad() {
    super.viewDidLoad()



    let dispatchQueue =
    dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)

    dispatch_async(dispatchQueue, {[weak self] in
        let mainBundle = NSBundle.mainBundle()

        /* Find the location of our file to feed to the audio player */

   var x = 1


        let filePath = mainBundle.pathForResource("\(x)", ofType:"mp3")
    //    }

        if let path = filePath{
            let fileData = NSData(contentsOfFile: path)

            var error:NSError?

            /* Start the audio player */
            self!.audioPlayer = AVAudioPlayer(data: fileData, error: &error)



            /* Did we get an instance of AVAudioPlayer? */
            if let player = self!.audioPlayer{
                /* Set the delegate and start playing */
                player.delegate = self
                if player.prepareToPlay() && player.play(){
                    /* Successfully started playing */
                } else {
                    /* Failed to play */
                }
            } else {
                /* Failed to instantiate AVAudioPlayer */
            }
        }
     })

}

}

您可以使用ColiseuPlayer ，它是用Swift編寫的音頻播放器框架。 它仍處於測試階段，但您可以使用它或檢查代碼。

演示：

import UIKit
import ColiseuPlayer

class ViewController: UIViewController {

    let player = ColiseuPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

        var list = [AudioFile]()

        if let urlFile = NSURL.fileURLWithPath(NSBundle.mainBundle().pathForResource("1.m4a", ofType: nil)!) {
            list.append(AudioFile(url: urlFile))
        }

        if let urlFile = NSURL.fileURLWithPath(NSBundle.mainBundle().pathForResource("2.m4a", ofType: nil)!) {
            list.append(AudioFile(url: urlFile))
        }

        if list.count > 0 {
            // Play first song (it will continue playing with the current playlist)
            player.playSong(0, songsList: list)
        }
    }
}
