如何在 Swift 中以编程方式使用主扬声器
How to use main speaker programmatically in Swift
我正在使用 webrtc 实现视频聊天。因为我想在其他参与者加入 session 时使用主扬声器。为此,我写了这段代码,但我的音量很低(意味着声音来自耳机)
func audioSetting() {
RTCAudioSession.sharedInstance().isAudioEnabled = true
let session = AVAudioSession.sharedInstance()
do {
try session.setCategory(AVAudioSession.Category.playAndRecord, mode: .videoChat, options: [])
if self.speakerOn {
try session.overrideOutputAudioPort(.none)
}
else {
try session.overrideOutputAudioPort(.speaker)
}
try session.setActive(true)
self.speakerOn = !self.speakerOn
}
catch let error {
print("Couldn't set audio to speaker: \(error)")
}
}
我正在使用 socket.IO、
开发 webRTC
func setSpeakerStates(enabled: Bool)
{
let session = AVAudioSession.sharedInstance()
var _: Error?
try? session.setCategory(AVAudioSession.Category.playAndRecord)
try? session.setMode(AVAudioSession.Mode.voiceChat)
if enabled {
try? session.overrideOutputAudioPort(AVAudioSession.PortOverride.speaker)
} else {
try? session.overrideOutputAudioPort(AVAudioSession.PortOverride.none)
}
try? session.setActive(true)
}
请在添加音频流和视频流后viewdidload结束时尝试此方法。
