Don't ask for mic permission

[AMKaffiOS]

The device only receives audio and video streams, does not collect audio and video, so do not need to apply for microphone permissions.

How can I prohibit the application of microphone permisson?

I have deleted the following method,but did not solve the problem.

• (RTCRtpSender )createAudioSender { RTCMediaConstraints constraints = [self defaultMediaAudioConstraints]; RTCAudioSource source = [_factory audioSourceWithConstraints:constraints]; RTCAudioTrack track = [_factory audioTrackWithSource:source trackId:kARDAudioTrackId]; RTCRtpSender *sender = [_peerConnection senderWithKind:kRTCMediaStreamTrackKindAudio streamId:kARDMediaStreamId]; sender.track = track; return sender; }
