 # 🔑 Token 过期机制
 
-## Token 即将过期
-
-```objc
-- (void)rtcSession:(SellyRTCSession *)session tokenWillExpire:(NSString *)token;
-```
-
-业务应立即向服务器请求新 Token：
-
-```objc

-```
-
-## Token 已过期（通话仍继续）
-
-```objc
-- (void)rtcSession:(SellyRTCSession *)session tokenExpired:(NSString *)token;
-```
-
-⚠️ 过期后通话不受影响，但**断网重连会失败**，务必及时更新 Token。
+- Token 将在 **60 秒前** 触发 `tokenWillExpire`
+- Token 过期后通话继续，但重连会失败
+- 请及时调用 `renewToken:`

-### Q1：多人远端画面如何渲染？
+`connectionState` 可读取当前房间状态：
 
-重复调用：

-canvas.view = remoteViewX;
-canvas.userId = @"userX";
-
-[self.session setRemoteCanvas:canvas];

-
-SDK 会根据 `userId` 做路由。

+- Connected  
+- Reconnecting

-### Q2：远端画面不显示？
+# ❓ 常见问题 FAQ
+
+### Q：远端画面不显示怎么办？
 
 检查：
 
-- remoteCanvas.view 是否正确添加  
-- remoteCanvas.userId 是否一致  
-- 是否重复 addSubview 覆盖  
-- 是否调用了 `setRemoteCanvas:`  
+1. 是否设置了正确的 `remoteCanvas.userId`  
+2. 是否 addSubview 到界面  
+3. 是否在 onUserJoined 后调用 setRemoteCanvas  
+
+### Q：如何实现摄像头与屏幕分享切换？
+
+1. 开启摄像头 → enableLocalVideo:YES  
+2. 开启屏幕分享 → startScreenCapture  
+3. 收到屏幕分享结束 → 恢复摄像头  
 
 ---
-
-### Q3：如何做画中画 (PiP)？
-
-将本地 + 远端视频放入一个 containerView：  
-
-```text
-[container addSubview:remoteView]
-[container addSubview:localView] // 小窗
-```
-
-并使用：
-
-```objc
-AVPictureInPictureControllerContentSource *source =
-    [[AVPictureInPictureControllerContentSource alloc] initWithActiveVideoCallSource:sampleBufferLayer
-                                                                          contentView:container];
