Hy,我试图了解即使你的iPhone设置为静音,是否有办法从播放器获取声音..是否有一个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

有人可以帮帮我吗？

我想问问是否有人已经为inapp-subscription（自动续订）实现了新的报价，如果可能的话，创建服务器端系统以使用php的p8密钥创建此签名的难度。我在Apple文档中找到了这个，我不确定是否了解它：https : //developer.apple.com/documentation/storekit/in-app_purchase/generating_a_signature_for_subscription_offers
