Create Broadcast Upload Extension in iOS

Step 1 : Open Target

Open your project with xcode, select File > New > Target in menu bar.

Step 2 : Select Target

Choose Broadcast Upload Extension, and click next.

Step 3 : Configure Broadcast Upload Extension

Enter extensions name in Product Name field, choose team from dropdown, Uncheck include UI extension field and click finish.

Step 4 : Activate Extension scheme

You will be prompted Activate "Your-Extension-name" scheme? pop-up, click activate.

Now, broadcast folder will appear in xcode left side bar.

Step 5 : Add External file in Created Extension

Open videosdk-rtc-react-native-sdk-example, Copy SampleUploader.swift, SocketConnection.swift, DarwinNotificationCenter.swift, and Atomic.swift files to your extension's folder and make sure they're added to the target.

Step 6 : Update SampleHandler.swift file

Open SampleHandler.swift and Copy SampleHandler.swift file content and paste it to your extensions SampleHandler.swift file.

Step 7 : Add Capability in App

In Xcode, go to YourappName > Signing & Capabilities. and click on +Capability to configure app group.

Select App Groups from list

After that, you have to select or add generated app group id which you have created before.

Step 8 : Add Capability in Extension

Go to Your-Extension-Name > Signing & Capabilities and configure App Group functionality which we had perform in previous steps. (Group id should be same for both targets)

Step 9 : Add App Group Id in Extension File

Go to extensions SampleHandler.swift file and paste your group Id in appGroupIdentifier constant.

Step 10 : Update App level info.plist file

1. Add a new key RTCScreenSharingExtension in Info.plist with the extension's Bundle Identifier as the value.
2. Add a new key RTCAppGroupIdentifier in Info.plist with the extension's App groups Id as the value.

Note : For extension's Bundle Identifier, go to TARGETS > Your-Extension-Name > Signing & Capabilities .

Create iOS Native Module for RPSystemBroadcastPickerView

Step 1 : Add Files in iOS Project

Go to Xcode > Your App, create new file name VideosdkRPK.swift

After click on Create button, it will prompt you to create bridging header.

After creating bridging header file, create Objective-c file name VideosdkRPK

• For VideosdkRPK.swift file, copy the content from VideosdkRPK.swift.

• For Appname-Bridging-Header file, just add #import "React/RCTEventEmitter.h" line.

• For VideosdkRPK.m file, copy the content from VideosdkRPK.m.

Step 2 : Integrate Native Module on React native side

• Create file with name VideosdkRPK.js and copy the code from VideosdkRPK.js.

• Add below lines for handling enable and disable screen share event.

import React, { useEffect } from "react";
import VideosdkRPK from "../VideosdkRPK";
import { TouchableOpacity, Text } from "react-native";

const { enableScreenShare, disableScreenShare } = useMeeting({});

useEffect(() => {
  VideosdkRPK.addListener("onScreenShare", (event) => {
    if (event === "START_BROADCAST") {
      enableScreenShare();
    } else if (event === "STOP_BROADCAST") {
      disableScreenShare();
    }
  });

  return () => {
    VideosdkRPK.removeSubscription("onScreenShare");
  };
}, []);

return (
  <>
    <TouchableOpacity
      onPress={() => {
        // Calling startBroadcast from iOS Native Module
        VideosdkRPK.startBroadcast();
      }}
    >
      <Text> Start Screen Share </Text>
    </TouchableOpacity>

    <TouchableOpacity
      onPress={() => {
        disableScreenShare();
      }}
    >
      <Text> Stop Screen Share </Text>
    </TouchableOpacity>
  </>
);

• VideosdkRPK.startBroadcast() method results below image

After clicking Start Broadcast button, we wiil be able to get the screen stream in session.
