Arka Plan Swift'de Ses Nasıl Oynanır?

Question

Gördüğünüz gibi bir ses yayını yayınlıyorum. Ama ana ekran düğmesine bastığımda ve uygulama akış duraklarından çıktığımda veya duyamıyorum. Arka planda akışa nasıl devam edebilirim ve kilit ekranından nasıl dinleyebilirim?

ViewController.Swift

için bunları uygulama Yetenek Arkaplan Modları (Ses ve AirPlay) ayarlayabilir ve AVAudioSessionCategoryPlayback için AVAudioSession kategorisini ayarlamak ve ayarlamanız gerekir
