Question

在我的应用中，声音播放为无限循环。但是当第一个循环结束时，它会等待2到3秒再次开始。我想禁用循环之间的间隔。你能帮帮我吗？

   import UIKit
import AVFoundation

class ViewController: UIViewController {


    var AudioPlayer = AVAudioPlayer();

    @IBOutlet weak var playb: UIButton!

    @IBAction func play(sender: UIButton) {
        if !AudioPlayer.playing {

        AudioPlayer.numberOfLoops = -1
        AudioPlayer.play()

            playb.setTitle("Stop Rain", forState: UIControlState.Normal)
        }   else {
        AudioPlayer.stop()
        playb.setTitle("Start Rain", forState: UIControlState.Normal)

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

        var rainSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("srs", ofType: "wav")!)
        AudioPlayer = AVAudioPlayer(contentsOfURL: rainSound, error: nil)
        AudioPlayer.prepareToPlay()

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

你在播放什么文件格式？

尝试播放非分组化文件格式，例如.wav或.aiff。像MP3和AAC这样的格式有少量的前导和尾随沉默，我认为AVAudioPlayer不允许你修剪！
