ios - 如果禁用音频/振动 AVPlayer 不发声 : on

Question

嘿，我想知道是否有办法让播放器发出声音，即使您的 iPhone 设置为静音。是否有 Swift 代码来启用音调？

//IMPOSRT FOUNDATION PER PLAYER
import AVFoundation

        let url = NSURL(string: "https://mywebsite.site/file/\(audio_r!)")
        playerItem = AVPlayerItem(URL: url!)
        player = AVPlayer(playerItem: playerItem!)
        let playerLayer = AVPlayerLayer(player: player!)
        playerLayer.frame = CGRectMake(0,0,300,50)
        self.view.layer.addSublayer(playerLayer)
        //imposto il volume
        player!.muted = false
        player!.volume = 1.0

有人可以帮助我吗？

播放类别不应服从静音开关

AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
AVAudioSession.sharedInstance().setActive(true)
