Ios 防止卸下耳机时出现视频暂停

使用的语言：Swift 2.3

我使用的是

avplayervewcontroller

，这是我的代码

let player = AVPlayer(URL: videoUrl!)            
playerViewController.player = player
playerViewController.showsPlaybackControls = false

我在这里做的是播放一段视频，这段视频应该是不可信的，不可屏蔽的

在这里，我使用

NSNotificationCenter

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.actionAfterVideo), name: AVPlayerItemDidPlayToEndTimeNotification, object: nil)

这将关闭我的

avplayervewcontroller

func actionAfterVideo() {
    playerViewController.dismissViewControllerAnimated(true, completion: nil)
}

除了用户插拔耳机外，所有这些功能都可以正常工作。这会自动暂停视频。他们当然可以通过使用

控制中心

来恢复，但这不是直观的

当耳机从手机上拔下时，我是否可以阻止视频暂停？

您可以添加一个通知来检查会话是否被中断，如下所示：

 NSNotificationCenter.defaultCenter().addObserver(self, selector: "playInterrupt:", name: AVAudioSessionInterruptionNotification, object: yourSession)

func playInterrupt(notification: NSNotification)
{
    if notification.name == AVAudioSessionInterruptionNotification && notification.userInfo != nil
    {
        var info = notification.userInfo!
        var intValue: UInt = 0

        (info[AVAudioSessionInterruptionTypeKey] as! NSValue).getValue(&intValue)

        if let type = AVAudioSessionInterruptionType(rawValue: intValue)
        {
            switch type
            {
            case .Began:
                player.pause()
            case .Ended:
                let timer = NSTimer.scheduledTimerWithTimeInterval(3, target: self, selector: "resumeNow:", userInfo: nil, repeats: false)
            }
        }
    }
}

func resumeNow(timer : NSTimer)
{
    player.play()
    print("restart")
}

并添加其

播放中断

实现，如下所示：

 NSNotificationCenter.defaultCenter().addObserver(self, selector: "playInterrupt:", name: AVAudioSessionInterruptionNotification, object: yourSession)

func playInterrupt(notification: NSNotification)
{
    if notification.name == AVAudioSessionInterruptionNotification && notification.userInfo != nil
    {
        var info = notification.userInfo!
        var intValue: UInt = 0

        (info[AVAudioSessionInterruptionTypeKey] as! NSValue).getValue(&intValue)

        if let type = AVAudioSessionInterruptionType(rawValue: intValue)
        {
            switch type
            {
            case .Began:
                player.pause()
            case .Ended:
                let timer = NSTimer.scheduledTimerWithTimeInterval(3, target: self, selector: "resumeNow:", userInfo: nil, repeats: false)
            }
        }
    }
}

func resumeNow(timer : NSTimer)
{
    player.play()
    print("restart")
}
