iOS 中多音频处理

iOS 中多音频处理

当我们自制作一个播放器的时候，会出现播放的 audio 被其他的比如系统来电或者是 App 内的其他 audio 打断的，这个时候，根据官方如下处理就行了

NotificationCenter.default.addObserver(self, selector: #selector(audioSessionInterruption(notification:)), name: Notification.Name.AVAudioSessionInterruption, object: nil)


 /// 音乐中断处理
    @objc fileprivate func audioSessionInterruption(notification: NSNotification) {
        guard let userInfo = notification.userInfo,
            let typeValue = userInfo[AVAudioSessionInterruptionTypeKey] as? UInt,
            let type = AVAudioSessionInterruptionType(rawValue: typeValue) else {
                return
        }
        if type == .began {
            // Interruption began, take appropriate actions
            player.pause()
        } else if type == .ended {
            if let optionsValue = userInfo[AVAudioSessionInterruptionOptionKey] as? UInt {
                let options = AVAudioSessionInterruptionOptions(rawValue: optionsValue)
                if options.contains(.shouldResume) {
                    // Interruption Ended - playback should resume
                    logger.verbose("Interruption Ended - playback should resume")
                    player.play()
                } else {
                    // Interruption Ended - playback should NOT resume
                    player.pause()
                }
            }
        }
    }
