【中文标题】Skype for business iOS SDK：无法启动音频服务

【英文标题】：Skype for business iOS SDK: unable to start audioservice

【问题描述】：

我正在集成 Skype 的 ios SDK，当我尝试从对话助手启动音频服务时。

do 
    try self.conversationHelper.conversation.audioService.start()

catch 
    print(error.localizedDescription)

我收到了这个错误。音频既没有通过也没有消失。 （但视频服务运行良好。）

我该如何解决这个问题？请帮忙。

【参考方案1】：

我设法找到了解决方案。我需要先初始化AVAudioSession 并将类别设置为AVAudioSessionCategoryPlayAndRecord 才能使其工作。

let audioSession: AVAudioSession = AVAudioSession.sharedInstance()
do
    try audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord)

catch let errorForCategory as Error
    print(errorForCategory.localizedDescription)

do
    try audioSession.setMode(AVAudioSessionModeVoiceChat)

catch let errorForMode as Error 
    print(errorForMode.localizedDescription)

编辑：如果您打算在视频聊天中使用 Airplay，您需要将模式设置为 AVAudioSessionModeVideoChat，如本文档中所述。 https://developer.apple.com/library/content/documentation/Audio/Conceptual/AudioSessionProgrammingGuide/AudioSessionBasics/AudioSessionBasics.html

do 
    try audioSession.setMode(AVAudioSessionModeVideoChat)

catch let errorForMode as Error 
    print(errorForMode.localizedDescription)
