How to enable（or use） RTCConfiguration in iOS SDK？

[zhang_s_1]

The Documents for iOS SDK didn't show how to use RTCConfiguration. I used it as the code below, no effect. What's the right usage for RTCConfiguration ?

I want to change the configuration for ICE. The interfaces of the RTCPeerClientConfiguration for ICE has only one(candidateNetworkPolicy).

iOS SDK Intel 官方文档只是给出了类说明，没有说明怎么使用。我使用了如下代码配置RTCConfiguration，好像没有起作用。正确使用方法应该是怎么样的？多谢指点！！

- (RTCPeerClient*)peerClient{
  if (_peerClient==nil){
    id<RTCP2PSignalingChannelProtocol> scc=[[SocketSignalingChannel alloc]init];
    RTCConfiguration* globalRTCconfig = [[RTCConfiguration alloc] init];
    globalRTCconfig.tcpCandidatePolicy = RTCTcpCandidatePolicyDisabled;
    globalRTCconfig.bundlePolicy = RTCBundlePolicyMaxBundle;
    globalRTCconfig.rtcpMuxPolicy = RTCRtcpMuxPolicyRequire;
    RTCPeerClientConfiguration* config=[[RTCPeerClientConfiguration alloc]init];

    NSArray *ice=[[NSArray alloc]initWithObjects:[[RTCIceServer alloc]initWithURLStrings:[[NSArray alloc]initWithObjects:@"turn:x.x.x.x?transport=udp", nil] username:@"xx" credential:@"xx"], nil];
    config.ICEServers=ice;
    config.mediaCodec.videoCodec=VideoCodecH264;
    config.candidateNetworkPolicy=RTCCandidateNetworkPolicyAll;
    _peerClient=[[RTCPeerClient alloc]initWithConfiguration:config signalingChannel:scc];
    [_peerClient addObserver:self];
  }
  return _peerClient;
}

Hi Zhang,

Setting RTCConfiguration is not supported at this time. Only items in RTCPeerClientConfiguration work.

I tested the demo（although I setted “config.candidateNetworkPolicy=RTCCandidateNetworkPolicyAll;” ）, RTCPeerClientConfiguration can't deal with networks changing case. During the call, the network switch(eg.wifi-->4G) will cause the call interrupt. I found that the ice is not configured properly. So I need to change the RTCConfiguration. If only items in RTCPeerClientConfiguration work, how to deal with the network change case seamlessly?

SDK 3.3 does not perform ICE restart when networks changed. config.candidateNetworkPolicy controls what kind of candidates are collected.
