我有一个使用Twilio的voip视频聊天应用程序,我试图为拨打电话的用户播放回铃音。但是每当调用didActivate:audioSession
时,我的AVAudioPlayer都会停止,导致回铃音仅播放片刻。在Callkit激活音频会话时,如何继续播放回铃音?这是我的代码:
func configure() {
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord, mode: AVAudioSessionModeVideoChat, options: [.mixWithOthers, .allowBluetooth, .defaultToSpeaker])
} catch {
print(error.localizedDescription)
}
let configuration = CXProviderConfiguration(localizedName: "Thirty")
configuration.maximumCallGroups = 1
configuration.maximumCallsPerCallGroup = 1
configuration.supportsVideo = true
configuration.supportedHandleTypes = [.generic]
if let callKitIcon = UIImage(named: "callkitIcon") {
configuration.iconTemplateImageData = UIImagePNGRepresentation(callKitIcon)
}
callKitProvider = CXProvider(configuration: configuration)
callKitProvider?.setDelegate(self, queue: nil)
let path = Bundle.main.path(forResource: "ringbackMorningSong.mp3", ofType:nil)!
let url = URL(fileURLWithPath: path)
ringbackAudioPlayer = try? AVAudioPlayer(contentsOf: url)
ringbackAudioPlayer?.numberOfLoops = -1
ringbackAudioPlayer?.prepareToPlay()
}
然后当用户点击"拨打电话"按钮,ringbackAudioPlayer开始播放。
然后执行CXStartCallAction
。然后调用didActivate:audioSession
,这就是我的回铃音停止的地方。
答案 0 :(得分:0)
可能不是最好的解决方案,但我通过在participantDidConnect 方法(twilio)中添加CXStartCallAction(call: uuid, handle: callHandle) 解决了这个问题。这样,AVAudioPlayer 就不会被 CallKit 打断,其他用户连接后就不需要 AVAudioPlayer 的声音了。
