Yet another WebRTC SDK for iOS?

Absolutely not. This plugin exposes the WebRTC W3C API for Cordova iOS apps (you know there is no WebRTC in iOS, right?), which means no need to learn "yet another WebRTC API" and no need to use a specific service/product/provider.

Who?

This plugin was initially developed at eFace2Face, and later maintained by the community, specially by Saúl Ibarra Corretgé (The OpenSource Warrior Who Does Not Burn).

Building

Last Tested WebRTC.framework version: M87 on cordova-plugin-iosrtc version 8.0.0+
Building: Guidelines for building a Cordova iOS application including the cordova-plugin-iosrtc plugin.

Sample Application

The cordova-plugin-iosrtc-sample include mutiple example for using cordova-plugin-iosrtc with JsSip, Janus, EasyRTC, and basic WebSocket Signaling. It's is used to test cordova-plugin-iosrtc new release and reproduce reported issues.

Usage

The plugin exposes the cordova.plugins.iosrtc JavaScript namespace which contains all the WebRTC classes and functions.

function TestRTCPeerConnectionLocal() {

  // Note: This allow this sample to run on any Browser
  var cordova = window.cordova;
  if (cordova && cordova.plugins && cordova.plugins.iosrtc) {

    // Expose WebRTC and GetUserMedia SHIM as Globals (Optional)
    // Alternatively WebRTC API will be inside cordova.plugins.iosrtc namespace
    cordova.plugins.iosrtc.registerGlobals();

    // Enable iosrtc debug (Optional)
    cordova.plugins.iosrtc.debug.enable('*', true);
  }

  // Run sample
  TestGetUserMedia().then(function (localStream) {
    TestRTCPeerConnection(localStream);
  });
}

if (document.readyState === "complete" || document.readyState === "loaded") {
  TestRTCPeerConnectionLocal();
} else {
  window.addEventListener("DOMContentLoaded", TestRTCPeerConnectionLocal);
}

// See ./extra/renderer-and-libwebrtc-tests.js for more samples usage.

In case you'd like to expose the API in the global namespace like regular browsers you can do the following:

// Just for Cordova apps.
document.addEventListener('deviceready', function () {
  // Just for iOS devices.
  if (window.device.platform === 'iOS') {
    cordova.plugins.iosrtc.registerGlobals();

    // load adapter.js
    var adapterVersion = 'latest';
    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "https://webrtc.github.io/adapter/adapter-" + adapterVersion + ".js";
    script.async = false;
    document.getElementsByTagName("head")[0].appendChild(script);
  }
});

And that's all. Now you have window.RTCPeerConnection, navigator.getUserMedia, etc.

Who Uses It

People and companies using cordova-plugin-iosrtc.

If you are using the plugin we would love to hear back from you!

Known Issues

iOS Safari and crash on WebSocket events

Don't call plugin methods within WebSocket events (onopen, onmessage, etc). There is an issue in iOS Safari (see issue #12). Instead run a setTimeout() within the WebSocket event if you need to call plugin methods on it.

Or better yet, include the provided ios-websocket-hack.js in your app and load into your index.html as follows:

<script src="cordova.js"></script>
<script src="ios-websocket-hack.min.js"></script>

HTML5 video API

There is no real media source attached to the <video> element so some HTML5 video events and properties are artificially emitted/set by the plugin on behalf of the video element.

Methods such as play(), pause() are not implemented. In order to pause a video just set enabled = false on the associated MediaStreamTrack.

iOS >= 13.3.1 Device support

To run on Devices with iOS >= 13.3.1, you need a valid Apple Developer account to sign the WebRTC dynamic frameworks for more info see https://stackoverflow.com/a/60090629/8691951
