OpentTok (iOS) How to subscribe to hasAudio stream changes
问题 I need a possibility in the TokBox iOS SDK to find out if a subscribed stream has audio dynamically / via an event. (OTStream.hasAudio) OTSubscriberDelegate provides callbacks for the subscribed video state subscriberVideoEnabled/Disabled but I can't find anything for audio. The JS SDK provides the StreamPropertyChangedEvent for this. The Android SDK provides the StreamPropertiesListener for this. iOS seems to be the only platform that doesn't have a proper solution. 回答1: TokBox Developer
