每當我只用musicPlayer.play()運行我的應用程序時,就沒有問題,但我希望應用程序從特定點開始,當我使用playAtTime(timeToPlay)音頻從不播放。我附上我的代碼的頂部(我相信它是唯一相關的部分)。任何幫助都是極好的!playAtTime不起作用,但play()與Swift中的AVAudioPlayer()

類RHCPViewController:UIViewController的{
var backgroundMusicPlayer = AVAudioPlayer()
let gradientLayer = CAGradientLayer()
var isPlaying: Bool = false
var timer: NSTimer?
var timeToPlay: NSTimeInterval = 0.00
override func viewDidLoad() {
super.viewDidLoad()
UIApplication.sharedApplication().statusBarHidden = true
}
@IBAction func playButtonWasClicked(sender: AnyObject) {
if isPlaying == false {
let song = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("CantStop", ofType: "mp3")!)
do {
backgroundMusicPlayer = try AVAudioPlayer(contentsOfURL: song, fileTypeHint: nil)
backgroundMusicPlayer.numberOfLoops = -1
backgroundMusicPlayer.prepareToPlay()
backgroundMusicPlayer.playAtTime(timeToPlay)
isPlaying = true
}
catch let error as NSError {
print(error.description)
}
