Join multiple rooms

Introduction

The same user can join multiple rooms at the same time, and publish streams, play streams, send real-time messages and receive message callbacks in multiple rooms at the same time.

This feature can be used for various use cases. Here are some examples:

• Cross-room interactions in live streaming
• Breakout rooms in virtual classrooms

Prerequisites

Before implementing the function, please make sure:

• ZEGO Express SDK has been integrated into the project to implement basic real-time audio and video functions. For details, please refer to Quick start .
• A project has been created in ZEGOCLOUD Console and applied for a valid AppID and AppSign. For details, please refer to Console - Project Information .

Setting up multi-room mode

Before initializing the SDK, call the setRoomMode interface, and set the room mode to multi-room mode through the ZegoRoomMode class, that is, the "mode" value is "ZegoRoomModeMultiRoom".

// Set room mode to multi-room mode
[ZegoExpressEngine setRoomMode:ZegoRoomModeMultiRoom];

Log in to rooms

Enter the roomID and other parameters, and call the loginRoom interface to log in to the room.

In multi-room mode, you can log in to multiple rooms at the same time, and the logged-in user information must be the same.

[[ZegoExpressEngine sharedEngine] loginRoom:@"multi_room_01" user:[ZegoUser userWithUserID:@"multi_room_user"]];

Publish streams

Pass in the streamID, roomID and other parameters, and call the startPublishingStream (with "ZegoPublisherConfig" parameter) interface to publish streams in the specified room.

ZegoPublisherConfig *config = [[ZegoPublisherConfig alloc] init];
config.roomID = @"multi_room_01";

[[ZegoExpressEngine sharedEngine] startPublishingStream:@"multi_room_publish_01" config:config channel:ZegoPublishChannelMain];

Play streams

Pass in the streamID, roomID and other parameters, and call the startPlayingStream (with "ZegoPlayerConfig" parameter) interface to play streams in the specified room.

ZegoPlayerConfig *config = [[ZegoPlayerConfig alloc] init];
config.roomID = @"multi_room_01";

[[ZegoExpressEngine sharedEngine] startPlayingStream:@"multi_room_player_01" canvas:[ZegoCanvas canvasWithView:self.playView] config:config];

Log out from rooms

Pass in the roomID and call the logoutRoom interface to exit the room.

[[ZegoExpressEngine sharedEngine] logoutRoom:@"multi_room_01"];
