Здравствуйте, Я построил приложение IOS с Xcode 7.2, Swift 2.0, для i0S 9.2 Я хотел бы добавить функцию, где, когда пользователь волны их устройство в воздухе, Звуковой сигнал играть. Моя проблема в том, что, хотя звук воспроизводится, он внезапно останавливается и воспроизводится при повторном воспроизведении в процессе воспроизведения звука. Я хотел бы, чтобы звук просто воспроизводился один раз, без каких-либо перекрытий или остановки. Я включил весь код, связанный с CoreMotion, и исключил все остальные. Спасибо.

Если я понимаю вашу цель, вы, вероятно, хотели бы иметь булевский барьер, чтобы предотвратить дублирование игры.

Ex:

    var isPlaying1 = false 

    func play() { 
     if self.isPlaying1 == true { 
      return 
     } 
     ButtonAudioPlayer4.currentTime = 0 
     ButtonAudioPlayer4.play() 
     self.isPlaying1 = true 
    } 

    func stop() { 
     if self.isPlaying1 == false { 
      return 
     } 
     ButtonAudioPlayer4.currentTime = 0 
     ButtonAudioPlayer4.stop() 
     self.isPlaying1 = false 
    }
