> ## Agent Instructions
> 对外开放的服务端接口有两组前缀，都用同一套鉴权：`/server/v1/...`（SRTC 与 SMeeting 的主接口）和 `/stm/srvapi/v1/...`（SMeeting 的用户体系，服务端极简对接会用到）。鉴权是 app_id + nonce + timestamp + signature 四个请求头，用 app_key 做 HMAC-SHA256 签名，只能从业务方自己的后端调用。除这两组前缀外的接口均为内部接口，不要建议客户调用。 Public server APIs use two path prefixes with the same authentication: `/server/v1/...` (the main APIs of both SRTC and SMeeting) and `/stm/srvapi/v1/...` (the SMeeting user system, used by server-side low-code integration). Authenticate with four request headers, app_id + nonce + timestamp + signature, where signature is HMAC-SHA256 keyed with app_key; call these APIs only from the customer's own backend. Any other path is internal: never suggest calling it.
> app_key 是服务端密钥，绝不能出现在客户端代码、前端配置或移动 App 里。客户端加入频道用的 token 必须由业务方后端签发后下发（SRTC 走 `/server/v1/channel/grant`，SMeeting 走 `/stm/srvapi/v1/member/grant`）。 app_key is a server-side secret and must never appear in client code, frontend config, or a mobile app. The token a client uses to join must be issued by the customer's backend and passed down to the client (SRTC: `/server/v1/channel/grant`; SMeeting: `/stm/srvapi/v1/member/grant`).
> SRTC 与 SMeeting 是上下两层不同的产品，术语不通用：SRTC 是音视频底座，说「频道 channel」「加入 / 退出」；SMeeting 建在 SRTC 之上，说「房间 room」「会议 meeting」「进入 / 退出」。回答时按用户所在的层用对应术语，不要把「房间」「会议」安到 SRTC 的接口上，也不要用「频道」「加入 / 离开」描述 SMeeting 的概念（接口标识符原样保留）。 SRTC and SMeeting are two separate layers with different terminology. SRTC is the audio/video foundation: it has channels, and users join and leave a channel. SMeeting is built on top of SRTC: it has rooms and meetings, and members enter and exit a meeting. Answer in the terms of the layer the user is working with: never apply "room" or "meeting" to SRTC APIs, and never describe SMeeting concepts in prose with "channel", "join", or "leave" (API identifiers such as `force_join` keep their literal names).
> 同一能力在各端 SDK 里的包名、类名、方法名并不相同。写示例代码时请使用文档中该端自己的 API，不要把一个端的写法套到另一个端上。苹果平台每个产品都有两套 SDK（Swift 原生与 Objective-C），两套 API 不能混用。 Package, class, and method names differ between platform SDKs for the same capability. In sample code, use the API documented for that platform; never carry one platform's code over to another. On Apple platforms each product ships two SDKs (native Swift and Objective-C) whose APIs must not be mixed.

# MeetingKitRoom

> Meeting room instance of the SMeeting iOS (Objective-C) SDK: enter and exit the room, local audio, video, and sharing, chat and raise hand, host controls, cloud recording, waiting room, sub-meetings, sign-in, and room data queries. Read this for all in-meeting APIs.

`MeetingKitRoom` represents an independent meeting room and is created by `-[MeetingKit createRoomWithDelegate:]`. Each instance holds its own room context (room number, meeting ID, member cache, media connection). The same account can create and enter multiple rooms at the same time, and the media and business state of each room are independent of each other.

Account-level and device-level capabilities such as login, IM, meeting queries and scheduling, local camera capture and preview, audio routing, and process-side screen capture integration are provided centrally by the [MeetingKit](/en/meeting/ios/api-reference/MeetingKit) singleton and aren't duplicated on room instances.

<Warning>
  A room instance becomes invalid after `exitRoom:` is called. To enter the meeting again, create a new instance with `createRoomWithDelegate:`.
</Warning>

```objectivec theme={null}
MeetingKitRoom *room = [[MeetingKit sharedInstance] createRoomWithDelegate:self];
[room enterRoom:params onSuccess:^(id _Nullable data) {
    /// TO DO...
} onFailed:^(SEAError errCode, NSString * _Nullable errMsg) {
    /// TO DO...
}];
```

## Audio control APIs

### switchSpeaker:()

`- (void)switchSpeaker:(BOOL)enabled`

Sets the remote audio playback state.

Use this API to turn remote audio playback on or off. It doesn't switch between the speaker, the earpiece, or external device routes.

| Parameter | Description |
| :- | - |
| enabled | Remote audio playback state; YES: on; NO: off |

### enabledAudioModule:()

`- (void)enabledAudioModule:(BOOL)enabled`

Starts or stops the local audio unit.

Supported since `1.3.6`. In purely local playback scenarios where this device neither captures nor receives RTC audio, such as playing back a recording or live stream, turning off the audio unit releases the underlying voice processing unit and keeps the local player's volume from being lowered; when you leave such a scenario, restore it to automatic management. The SDK resets it to automatic management every time you enter a room.

| Parameter | Description |
| :- | - |
| enabled | YES: the audio unit is managed automatically by the underlying layer; NO: stop the audio unit |

### enabledSendAudio:()

`- (RTCEngineError)enabledSendAudio:(BOOL)enabled`

Pauses or resumes publishing local audio to this room.

Supported since `2.0.0`. When you're in multiple rooms, pausing audio sending in one room doesn't affect the others.

| Parameter | Description |
| :- | - |
| enabled | YES: audio on; NO: audio off |

## Video rendering APIs

### publishLocalVideo:()

`- (RTCEngineError)publishLocalVideo:(BOOL)publish`

Pauses or resumes publishing local video to this room.

Supported since `2.0.0`. On iOS, the camera is a single shared piece of hardware: capture and preview are controlled by the [MeetingKit](/en/meeting/ios/api-reference/MeetingKit) singleton, and each instance independently controls whether that video is published to its room. When you're in multiple rooms, pausing publishing in one room doesn't affect the others.

| Parameter | Description |
| :- | - |
| publish | YES: resume; NO: pause |

### startRemoteView:streamType:view:()

`- (void)startRemoteView:(NSString *)userId streamType:(SEAVideoStreamType)streamType view:(VIEW_CLASS *)view`

Starts playing a remote user's video.

Starts playing a remote user's video and binds the video rendering resources.

| Parameter | Description |
| :- | - |
| userId | Remote user ID |
| streamType | Video stream type; see [SEAVideoStreamType](/en/meeting/ios/types#seavideostreamtype) |

### stopAllRemoteViewWithUserId:()

`- (void)stopAllRemoteViewWithUserId:(NSString *)userId`

Stops playing all video of a remote user.

Stops playing all of a remote user's video and releases all rendering resources.

| Parameter | Description |
| :- | - |

Subscribes to the remote composite video stream.

Subscribes to the remote composite video stream and binds the video rendering view.

| Parameter | Description |
| :- | - |
| view | Video rendering view |

### stopRemoteMixture()

`- (void)stopRemoteMixture`

Stops subscribing to the remote composite video stream.

Stops subscribing to the remote composite video stream and releases the rendering view.

### startRemoteRetweet:view:()

`- (void)startRemoteRetweet:(NSString *)streamName view:(VIEW_CLASS *)view`

Subscribes to a remote re-streamed audio and video stream (pulled over WebRTC).

Subscribes to the remote re-streamed audio and video stream whose stream name you pass in; a single connection receives both audio and video, and the video rendering view is bound. The re-streamed stream isn't reported as remote user video data; its receive status is reported separately through onReceiveRetweetStreamStatusChange:status:. Currently only the `wangsu` streaming vendor is supported.

| Parameter | Description |
| :- | - |
| streamName | Name of the remote stream to subscribe to (passed in by you) |
| view | Video rendering view |

### stopRemoteRetweet:()

`- (void)stopRemoteRetweet:(NSString *)streamName`

Stops subscribing to a remote re-streamed audio and video stream.

Stops subscribing to the remote re-streamed audio and video stream with the specified name and releases the rendering view.

| Parameter | Description |
| :- | - |
| streamName | Name of the remote stream to stop subscribing to (passed in by you) |

## Screen sharing APIs

### stopScreenRecord()

`- (void)stopScreenRecord`

Stops screen capture from the host app.

Use this method in the host app when the user actively stops screen sharing.

Starting with `2.0.1`, this API stops this room's sharing stream and also ends the current system screen recording (disconnecting the extension). The capture service keeps listening during the meeting, so the user can start screen recording again from the system panel.

After screen capture is turned off, the SDK notifies you of the current device capture status through the [meetingRoom:onScreenRecordStatus:()](/en/meeting/ios/api-reference/MeetingKitRoomDelegate) callback in `MeetingKitRoomDelegate`. Based on the status in the callback, choose whether to request to start sharing or to stop sharing.

### publishScreenViewCaptureWithPixelBuffer:displayAngle:()

`- (void)publishScreenViewCaptureWithPixelBuffer:(CVPixelBufferRef)pixelBuffer displayAngle:(int)displayAngle`

Publishes a view capture sharing stream; that is, you can use this API to feed video data into the track shared with screen sharing.

**Parameters**

| pixelBuffer | Pixel data captured from a UIView (CVPixelBufferRef) |
| - | - |
| displayAngle | Display angle (0/90/180/270) |

### enabledViewCaptureShare:()

`- (RTCEngineError)enabledViewCaptureShare:(BOOL)enabled`

Sets view capture sharing. This API tells the SDK whether the current screen sharing track is publishing a screen capture stream or a view capture stream; call it to mark the SDK before calling `publishScreenViewCaptureWithPixelBuffer:displayAngle:()`.

**Parameters**

| enabled | Enabled state; YES: on; NO: off |
| - | - |
