    TUIKaraoke is an open-source audio/video UI component that you can integrate into your project to bring online karaoke, seat management, gift giving/receiving, text chat, and other TRTC features to your application. TUIKaraoke requires only a few lines of code and also supports the Android platform. Its basic features are shown below:
    All TUIKit components are based on two basic PaaS services of Tencent Cloud, namely TRTC and Chat. When you activate TRTC, the Chat SDK Trial Edition (which supports up to 100 DAUs) will also be activated automatically. For Chat billing details, see Pricing.


    Step 1. Download and import the TUIKaraoke component

    Go to GitHub, clone or download the code, copy the Source, Resources, and TXAppBasic folders and the TUIKaraoke.podspec file in the iOS directory to your project, and complete the following import operations:
    Add the following import commands to your Podfile:
    pod 'TUIKaraoke', :path => "./", :subspecs => ["TRTC"]
    pod 'TXLiteAVSDK_TRTC'
    pod 'TXAppBasic', :path => "TXAppBasic/"
    Open Terminal and run the following installation command in the directory of the Podfile:
    pod install

    Step 2. Configure permissions

    Configure permission requests for your app in the info.plist file of your project. The SDKs need the following permissions (on iOS, the mic access must be requested at runtime):
    <string>`TUIKaraoke` needs to access your mic.</string>

    Step 3. Initialize and log in to the component

    For more information on relevant APIs, see TRTCKaraoke (iOS).
    // 1. Initialize
    let karaokeRoom = TRTCKaraokeRoom.shared()
    karaokeRoom.setDelegate(delegate: self)
    // 2. Log in
    karaokeRoom.login(SDKAppID: Int32(SDKAppID), UserId: UserId, UserSig: ProfileManager.shared.curUserSig()) { code, message in
    if code == 0 {
    // Logged in
    Parameter description:
    SDKAppID: TRTC application ID. If you haven't activated TRTC, log in to the TRTC console, create a TRTC application, click Application Info, and select the Quick Start tab to view its SDKAppID.
    SecretKey: TRTC application key. Each secret key corresponds to an SDKAppID. You can view your application’s secret key on the Application Management page of the TRTC console.
    userId: Current user ID, which is a custom string that can contain up to 32 bytes of letters and digits (special characters are not supported).
    userSig: The security protection signature calculated based on SDKAppID, userId, and Secretkey. You can click here to directly generate a debugging userSig online. For more information, see UserSig.

    Step 4. Implement the online karaoke scenario

    1. The room owner creates a room through TUIKaraoke.createRoom.
    int roomId = "Room ID";
    let param = RoomParam.init()
    param.roomName = "Room name";
    param.needRequest = false; // Whether permission is required for listeners to speak.
    param.seatCount = 8; // Number of seats in the room. Set it to `8`.
    param.coverUrl = "URL of room cover image";
    karaokeRoom.createRoom(roomID: Int32(roomInfo.roomID), roomParam: param) { [weak self] (code, message) in
    guard let `self` = self else { return }
    if code == 0 {
    // Room created successfully
    2. A listener enters the room through TUIKaraoke.enterRoom.
    karaokeRoom.enterRoom(roomID: roomInfo.roomID) { [weak self] (code, message) in
    guard let `self` = self else { return }
    if code == 0 {
    // Entered room successfully
    3. A listener turns their mic on through TUIKaraoke.enterSeat.
    // 1. A listener calls an API to mic on
    int seatIndex = 1;
    karaokeRoom.enterSeat(seatIndex: seatIndex) { [weak self] (code, message) in
    guard let `self` = self else { return }
    if code == 0 {
    // Mic turned on successfully
    // 2. The listener receives the `onSeatListChange` callback and refreshes the seat list
    func onSeatListChange(seatInfoList: [SeatInfo]) {
    You can implement other seat management operations as instructed in TRTCKaraoke (iOS) or by referring to the TUIKaraoke demo project.
    4. Play back songs and try out the karaoke scenario You can get the music ID and URL to play back a song. For more information, see Music Playback APIs.
    // Play back the music
    karaokeRoom.startPlayMusic(musicID: musicID, originalUrl: muscicLocalPath, accompanyUrl: accompanyLocalPath);
    // Stop the music
    After completing the previous steps, you can implement the basic karaoke features. If your business needs more features such as chat and gift giving, you can integrate the following capabilities:

    Step 5. Add the text chat feature (optional)

    If you want implement a text chat feature between speakers and listeners, implement message sending/receiving as follows: For more information on relevant APIs, see sendRoomTextMsg.
    // Sender: Sends text chat messages
    karaokeRoom.sendRoomTextMsg(message: message) { [weak self] (code, message) in
    if code == 0 {
    // Sent successfully
    // Receiver: Listens for text chat messages
    karaokeRoom.setDelegate(delegate: self)
    func onRecvRoomTextMsg(message: String, userInfo: UserInfo) {
    debugPrint("Received a message from" + userInfo.userName + ": " + message)

    Step 6. Add the gift giving feature (optional)

    You can implement gift giving, receiving, and displaying as follows:
    // Sender: Customize `IMCMD_GIFT` to distinguish between gift messages
    karaokeRoom.sendRoomCustomMsg(cmd: kSendGiftCmd, message: message) { code, msg in
    if (code == 0) {
    // Sent successfully
    // Receiver: Listens for gift messages
    karaokeRoom.setDelegate(delegate: self)
    func onRecvRoomCustomMsg(cmd: String, message: String, userInfo: UserInfo) {
    if cmd == kSendGiftCmd {
    debugPrint("Received a gift from" + userInfo.userName + ": " + message)


    Does the TUIKaraoke component support sound effect features such as voice change, tone change, and reverb?

    Yes. For more information, see the TUIKaraoke demo project.
