在暂停后的AVAudioPlayer中，歌曲不会在Swift上继续播放

Question

在暂停后的AVAudioPlayer中，歌曲不会继续，在Swift上重新开始播放。问题是当我选择暂停按钮，然后再次播放按钮时，它应该从开始。

import UIKit 
import AVFoundation 
class DetailViewController: UIViewController { 

let musicArray:[String] = ["reamon", "sandman"] 

var audioPlayer: AVAudioPlayer? 

var songIndex:Int = 0 

@IBAction func pauseButton(sender: AnyObject) { 
    audioPlayer!.pause() 

} 

@IBAction func playButton(sender: AnyObject) { 

    let mySound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(musicArray[songIndex], ofType: "mp3")!) 

    do{ 
     audioPlayer = try AVAudioPlayer(contentsOfURL: mySound) 
     audioPlayer!.prepareToPlay() 
     audioPlayer!.play() 
    } catch { 
     print("Error getting the audio file") 
    } 

} 

@IBOutlet weak var stopButtonOutlet: UIButton! 

@IBAction func stopButton(sender: AnyObject) { 
    audioPlayer!.stop() 
    audioPlayer!.currentTime = 0 
} 

func playSongAtIndex(index: Int) { 

    songIndex = index 

}

我做另一种方式。这是播放和暂停的一个按钮。

@IBAction func playPauseButton(sender: AnyObject) { 

    if (player.playing == true) { 
     player.stop() 
     playPauseButtonOutlet.setImage(UIImage(named: "play.jpg"), forState: UIControlState.Normal) 
    } else { 
     player.play() 
     playPauseButtonOutlet.setImage(UIImage(named: "pause.jpg"), forState: UIControlState.Normal) 
    } 
}

你初始化你的播放按钮操作时都AVAudioPlayer尝试初始化你AVAudioPlayer其中将只调用一次其他一些方法试试这个

override func viewWillAppear(animated: Bool) 
{ 
     self .intiAudioPlayer() 
} 

func intiAudioPlayer() 
{ 

     let mySound = NSURL(fileURLWithPath:NSBundle.mainBundle().pathForResource(musicArray[songIndex], ofType: "mp3")!) 

    do 
    { 
     audioPlayer = try AVAudioPlayer(contentsOfURL: mySound) 
     audioPlayer!.prepareToPlay() 
    } 
    catch { 
     print("Error getting the audio file") 
    } 
} 

您的播放按钮操作将只包含这么多的代码

@IBAction func playButton(sender: AnyObject) 
{ 
    audioPlayer!.play() 
}
