+# KBChatTableView API 快速参考
+
+## 📦 Import
+
+```objective-c
+#import "KBChatTableView.h"
+```
+
+---
+
+## 🎯 初始化
+
+```objective-c
+KBChatTableView *chatView = [[KBChatTableView alloc] init];
+[self.view addSubview:chatView];
+
+[chatView mas_makeConstraints:^(MASConstraintMaker *make) {
+    make.edges.equalTo(self.view);
+}];
+```
+
+---
+
+## 📝 API 方法
+
+### 添加用户消息
+```objective-c
+- (void)addUserMessage:(NSString *)text;
+```
+
+**示例：**
+```objective-c
+[self.chatView addUserMessage:@"你好"];
+```
+
+---
+
+### 添加 AI 消息（带语音）
+```objective-c
+- (void)addAssistantMessage:(NSString *)text
+              audioDuration:(NSTimeInterval)duration
+                  audioData:(nullable NSData *)audioData;
+```
+
+**示例：**
+```objective-c
+// 有语音
+[self.chatView addAssistantMessage:@"你好！"
+                     audioDuration:3.0
+                         audioData:audioData];
+
+// 无语音
+[self.chatView addAssistantMessage:@"你好！"
+                     audioDuration:0
+                         audioData:nil];
+```
+
+---
+
+### 更新最后一条 AI 消息（打字机效果）
+```objective-c
+- (void)updateLastAssistantMessage:(NSString *)text;
+```
+
+**示例：**
+```objective-c
+// 1. 先添加空消息
+[self.chatView addAssistantMessage:@"" audioDuration:0 audioData:nil];
+
+// 2. 逐步更新
+[self.chatView updateLastAssistantMessage:@"你"];
+[self.chatView updateLastAssistantMessage:@"你好"];
+[self.chatView updateLastAssistantMessage:@"你好！"];
+
+// 3. 标记完成
+[self.chatView markLastAssistantMessageComplete];
+```
+
+---
+
+### 标记最后一条 AI 消息完成
+```objective-c
+- (void)markLastAssistantMessageComplete;
+```
+
+---
+
+### 清空所有消息
+```objective-c
+- (void)clearMessages;
+```
+
+---
+
+### 滚动到底部
+```objective-c
+- (void)scrollToBottom;
+```
+
+---
+
+## 🎨 消息类型
+
+### KBChatMessage
+
+```objective-c
+@interface KBChatMessage : NSObject
+
+@property (nonatomic, assign) KBChatMessageType type;
+@property (nonatomic, copy) NSString *text;
+@property (nonatomic, strong) NSDate *timestamp;
+@property (nonatomic, assign) NSTimeInterval audioDuration;
+@property (nonatomic, strong, nullable) NSData *audioData;
+@property (nonatomic, assign) BOOL isComplete;
+
+// 便捷构造方法
++ (instancetype)userMessageWithText:(NSString *)text;
++ (instancetype)assistantMessageWithText:(NSString *)text
+                           audioDuration:(NSTimeInterval)duration
+                               audioData:(nullable NSData *)audioData;
++ (instancetype)timeMessageWithTimestamp:(NSDate *)timestamp;
+
+@end
+```
+
+### KBChatMessageType
+
+```objective-c
+typedef NS_ENUM(NSInteger, KBChatMessageType) {
+    KBChatMessageTypeUser,      // 用户消息
+    KBChatMessageTypeAssistant, // AI 回复
+    KBChatMessageTypeTime       // 时间戳
+};
+```
+
+---
+
+## 🔊 音频时长计算
+
+### 方法 1：使用 AVAudioPlayer（推荐）
+
+```objective-c
+NSError *error = nil;
+AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:audioData error:&error];
+NSTimeInterval duration = player ? player.duration : 0;
+
+[self.chatView addAssistantMessage:text
+                     audioDuration:duration
+                         audioData:audioData];
+```
+
+### 方法 2：估算（不准确）
+
+```objective-c
+// 假设：16kHz 采样率，单声道，16 位
+NSTimeInterval duration = audioData.length / (16000.0 * 1 * 2);
+```
+
+---
+
+## ⏰ 时间戳规则
+
+时间戳自动插入，无需手动添加：
+
+- ✅ 第一条消息
+- ✅ 距离上一条消息 > 5 分钟
+- ✅ 跨天的消息
+
+**时间格式：**
+- 今天：`16:36`
+- 昨天：`昨天 16:36`
+- 其他：`01月23日 16:36`

+    [self.chatView markLastAssistantMessageComplete];
+});
+```
+
+---
+
+## 🎨 自定义配置
+
+### 修改时间戳间隔
+
+在 `KBChatTableView.m` 中：
+```objective-c
+static const NSTimeInterval kTimestampInterval = 5 * 60; // 秒
+```
+
+### 修改气泡颜色
+
+**用户消息**（`KBChatUserMessageCell.m`）：
+```objective-c
+self.bubbleView.backgroundColor = [UIColor colorWithRed:0.94 green:0.94 blue:0.94 alpha:1.0];
+```
+
+**AI 消息**（`KBChatAssistantMessageCell.m`）：
+```objective-c
+self.bubbleView.backgroundColor = [UIColor colorWithRed:0.2 green:0.2 blue:0.2 alpha:0.7];
+```

+1. **音频格式**：MP3、AAC、M4A 等 AVAudioPlayer 支持的格式
+2. **线程安全**：UI 更新必须在主线程
+3. **内存管理**：大量消息时考虑限制数量
+4. **音频会话**：确保配置了 AVAudioSession

+# KBChatTableView 使用说明
+
+## 概述
+
+`KBChatTableView` 是一个完整的聊天 UI 组件，支持：
+- ✅ 用户消息（右侧气泡）
+- ✅ AI 消息（左侧气泡 + 语音播放按钮）
+- ✅ 时间戳（自动插入，5 分钟间隔）
+- ✅ 语音播放功能
+- ✅ 打字机效果
+
+## 快速开始
+
+### 1. 在 ViewController 中引入
+
+```objective-c
+#import "KBChatTableView.h"
+
+@interface YourViewController ()
+@property (nonatomic, strong) KBChatTableView *chatView;
+@end
+```
+
+### 2. 初始化并布局
+
+```objective-c
+- (void)viewDidLoad {
+    [super viewDidLoad];
+    
+    self.chatView = [[KBChatTableView alloc] init];
+    self.chatView.backgroundColor = [UIColor clearColor];
+    [self.view addSubview:self.chatView];
+    
+    [self.chatView mas_makeConstraints:^(MASConstraintMaker *make) {
+        make.top.equalTo(self.view.mas_safeAreaLayoutGuideTop);
+        make.left.right.equalTo(self.view);
+        make.bottom.equalTo(self.recordButton.mas_top).offset(-16);
+    }];
+}
+```
+
+### 3. 添加消息
+
+#### 添加用户消息
+```objective-c
+[self.chatView addUserMessage:@"你好"];
+```
+
+#### 添加 AI 消息（带语音）
+```objective-c
+NSString *text = @"你好，很高兴见到你！";
+NSTimeInterval duration = 6.0; // 6 秒
+NSData *audioData = ...; // 从 TTS 获取的音频数据
+
+[self.chatView addAssistantMessage:text
+                     audioDuration:duration
+                         audioData:audioData];
+```
+
+#### 添加 AI 消息（无语音）
+```objective-c
+[self.chatView addAssistantMessage:@"你好"
+                     audioDuration:0
+                         audioData:nil];
+```
+
+### 4. 打字机效果
+
+```objective-c
+// 1. 添加空消息占位
+[self.chatView addAssistantMessage:@""
+                     audioDuration:0
+                         audioData:nil];
+
+// 2. 逐步更新文本
+[self.chatView updateLastAssistantMessage:@"你"];
+[self.chatView updateLastAssistantMessage:@"你好"];
+[self.chatView updateLastAssistantMessage:@"你好，"];
+[self.chatView updateLastAssistantMessage:@"你好，很高兴见到你！"];
+
+// 3. 标记完成
+[self.chatView markLastAssistantMessageComplete];
+```
+
+### 5. 其他操作
+
+```objective-c
+// 清空所有消息
+[self.chatView clearMessages];
+
+// 滚动到底部
+[self.chatView scrollToBottom];
+```
+
+## 集成到 KBAiMainVC
+
+### 替换现有的 KBAiChatView
+
+在 `KBAiMainVC.m` 中：
+
+```objective-c
+// 1. 修改 import
+#import "KBChatTableView.h"
+
+// 2. 修改属性声明
+@property (nonatomic, strong) KBChatTableView *chatView;
+
+// 3. 在 setupUI 中初始化
+self.chatView = [[KBChatTableView alloc] init];
+self.chatView.backgroundColor = [UIColor clearColor];
+[self.view addSubview:self.chatView];
+
+[self.chatView mas_makeConstraints:^(MASConstraintMaker *make) {
+    make.top.equalTo(self.transcriptLabel.mas_bottom).offset(8);
+    make.left.right.equalTo(self.view);
+    make.bottom.lessThanOrEqualTo(self.recordButton.mas_top).offset(-16);
+}];
+
+// 4. 在 Deepgram 回调中添加消息
+- (void)deepgramStreamingManagerDidReceiveFinalTranscript:(NSString *)text {
+    // ... 现有代码 ...
+    
+    // 添加用户消息
+    [self.chatView addUserMessage:finalText];
+    
+    // AI 回复完成后
+    [self.chatView addAssistantMessage:polishedText
+                         audioDuration:audioData.length / 16000.0 // 估算时长
+                             audioData:audioData];
+}
+```
+
+## 时间戳显示规则
+
+时间戳会在以下情况自动插入：
+1. 第一条消息
+2. 距离上一条消息超过 5 分钟
+3. 跨天的消息
+
+时间格式：
+- 今天：`16:36`
+- 昨天：`昨天 16:36`
+- 其他：`01月23日 16:36`
+
+## 语音播放
+
+- 点击语音按钮播放音频
+- 播放时按钮变为暂停图标
+- 点击其他消息的语音按钮会停止当前播放
+- 播放完成后自动恢复播放图标
+
+## 自定义样式
+
+### 修改气泡颜色
+
+在对应的 Cell 文件中修改：
+
+**用户消息** (`KBChatUserMessageCell.m`):
+```objective-c
+self.bubbleView.backgroundColor = [UIColor colorWithRed:0.94 green:0.94 blue:0.94 alpha:1.0];
+```
+
+**AI 消息** (`KBChatAssistantMessageCell.m`):
+```objective-c
+self.bubbleView.backgroundColor = [UIColor colorWithRed:0.2 green:0.2 blue:0.2 alpha:0.7];
+```
+
+### 修改时间戳间隔
+
+在 `KBChatTableView.m` 中修改：
+```objective-c
+static const NSTimeInterval kTimestampInterval = 5 * 60; // 改为你想要的秒数
+```
+
+## 注意事项
+
+1. **音频数据格式**：确保传入的 `audioData` 是 AVAudioPlayer 支持的格式（如 MP3、AAC）
+2. **内存管理**：大量消息时考虑分页加载
+3. **线程安全**：UI 更新需要在主线程执行
+4. **音频会话**：播放音频前确保配置了 AVAudioSession
+
+## 完整示例
+
+```objective-c
+// 模拟对话
+[self.chatView addUserMessage:@"你好"];
+
+dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 1 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
+    NSString *aiText = @"你好！很高兴见到你，有什么可以帮助你的吗？";
+    NSData *audioData = [self generateMockAudioData]; // 模拟音频数据
+    [self.chatView addAssistantMessage:aiText
+                         audioDuration:6.0
+                             audioData:audioData];
+});
+```

+# KBAiMainVC 集成 KBChatTableView 说明
+
+## ✅ 已完成的修改
+
+### 1. Import 修改
+```objective-c
+// 原来
+#import "KBAiChatView.h"
+
+// 修改为
+#import "KBChatTableView.h"
+```
+
+---
+
+### 2. 属性类型修改
+```objective-c
+// 原来
+@property(nonatomic, strong) KBAiChatView *chatView;
+
+// 修改为
+@property(nonatomic, strong) KBChatTableView *chatView;
+```
+
+---
+
+### 3. 初始化修改
+```objective-c
+// 原来
+self.chatView = [[KBAiChatView alloc] init];
+
+// 修改为
+self.chatView = [[KBChatTableView alloc] init];
+```
+
+---
+
+### 4. 布局约束修改（从底部向上显示）
+
+**原来的布局：**
+```objective-c
+[self.chatView mas_makeConstraints:^(MASConstraintMaker *make) {
+    make.top.equalTo(self.transcriptLabel.mas_bottom).offset(8);
+    make.left.equalTo(self.view).offset(16);
+    make.right.equalTo(self.view).offset(-16);
+    make.bottom.lessThanOrEqualTo(self.recordButton.mas_top).offset(-16);
+}];
+```
+
+**修改为（从底部向上）：**
+```objective-c
+[self.chatView mas_makeConstraints:^(MASConstraintMaker *make) {
+    make.left.right.equalTo(self.view);
+    make.bottom.equalTo(self.tabbarBackgroundView.mas_top).offset(-8);
+    make.top.greaterThanOrEqualTo(self.transcriptLabel.mas_bottom).offset(8);
+}];
+```
+
+**说明：**
+- `bottom` 约束到 `tabbarBackgroundView` 的顶部，确保从底部开始
+- `top` 使用 `greaterThanOrEqualTo`，允许内容向上扩展
+- 移除了左右的 16pt 边距，让聊天视图占满宽度（气泡内部已有边距）
+
+---
+
+### 5. 消息添加逻辑修改
+
+#### 5.1 添加用户消息（保持不变）
+```objective-c
+[self.chatView addUserMessage:finalText];
+```
+
+#### 5.2 添加 AI 消息（带语音数据）
+
+**在 `deepgramStreamingManagerDidReceiveFinalTranscript` 中：**
+
+```objective-c
+// 1. 添加用户消息
+[self.chatView addUserMessage:finalText];
+
+// 2. 生成 AI 回复后，添加带语音的消息
+// 计算音频时长
+NSTimeInterval duration = 0;
+NSError *playerError = nil;
+AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:audioData
+                                                       error:&playerError];
+if (!playerError && player) {
+    duration = player.duration;
+}
+
+// 添加 AI 消息（带语音）
+[self.chatView addAssistantMessage:polishedText
+                     audioDuration:duration
+                         audioData:audioData];
+
+// 播放音频
+[self playAiAudioData:audioData];
+```
+
+**错误处理：**
+```objective-c
+// 如果语音生成失败，仍然添加文本消息（无语音）
+if (ttsError) {
+    [KBHUD showError:ttsError.localizedDescription ?: @"语音生成失败"];
+    [self.chatView addAssistantMessage:polishedText
+                         audioDuration:0
+                             audioData:nil];
+    return;
+}
+```
+
+---
+
+#### 5.3 打字机效果修改
+
+**在 `voiceChatStreamingManagerDidReceiveLLMStart` 中：**
+```objective-c
+// 原来
+[self.chatView addAssistantMessage:@""];
+
+// 修改为
+[self.chatView addAssistantMessage:@"" audioDuration:0 audioData:nil];
+```
+
+**在 `orchestrator.onSpeakingStart` 中：**
+```objective-c
+// 原来
+[self.chatView addAssistantMessage:@""];
+
+// 修改为
+[self.chatView addAssistantMessage:@"" audioDuration:0 audioData:nil];
+```
+
+---
+
+### 6. VoiceChatStreamingManager 完成回调修改
+
+**在 `voiceChatStreamingManagerDidCompleteWithTranscript` 中：**
+
+```objective-c
+// 计算音频时长
+NSTimeInterval duration = 0;
+if (self.voiceChatAudioBuffer.length > 0) {
+    NSError *error = nil;
+    AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:self.voiceChatAudioBuffer
+                                                           error:&error];
+    if (!error && player) {
+        duration = player.duration;
+    }
+}
+
+// 添加消息时带上音频数据
+if (transcript.length > 0) {
+    [self.chatView addAssistantMessage:transcript
+                         audioDuration:duration
+                             audioData:self.voiceChatAudioBuffer.length > 0 ? self.voiceChatAudioBuffer : nil];
+}
+```
+
+---
+
+## 🎯 核心改进
+
+### 1. 从底部向上显示
+- 聊天视图的 `bottom` 约束到 `tabbarBackgroundView.top`
+- 新消息会从底部向上堆叠
+- 自动滚动到最新消息
+
+### 2. 语音功能集成
+- AI 消息带有语音数据和时长
+- 点击语音按钮可播放
+- 显示语音时长（如 "6""）
+
+### 3. 时间戳自动显示
+- 第一条消息显示时间
+- 超过 5 分钟自动插入时间戳
+- 跨天消息显示日期
+
+### 4. 用户体验优化
+- 消息气泡左右对齐清晰
+- 语音播放状态可视化
+- 自动滚动到最新消息

+## 🐛 可能的问题
+
+### 1. 语音按钮不显示
+**原因：** `audioData` 为 nil 或长度为 0  
+**解决：** 检查 TTS 返回的音频数据
+
+### 2. 消息不从底部显示
+**原因：** 布局约束错误  
+**解决：** 确保 `bottom` 约束到 `tabbarBackgroundView.top`
+
+### 3. 时间戳不显示
+**原因：** 消息的 `timestamp` 未设置  
+**解决：** `KBChatMessage` 会自动设置当前时间
+
+### 4. 点击语音按钮没反应
+**原因：** 音频数据格式不正确  
+**解决：** 确保音频数据是 AVAudioPlayer 支持的格式（MP3、AAC、M4A）
+
+---
+
+## 🎉 完成！
+
+现在 `KBAiMainVC` 已经成功集成了新的 `KBChatTableView`，具备以下特性：
+
+✅ 从底部向上显示消息

+# 聊天 UI 实现总结
+
+## ✅ 已完成
+
+根据你的需求，我已经完整实现了一个类似微信的聊天 UI 系统，包含以下功能：
+
+### 核心功能
+- ✅ 用户消息（右侧浅色气泡）
+- ✅ AI 消息（左侧深色气泡）
+- ✅ 语音播放按钮（AI 消息左上角）
+- ✅ 语音时长显示（如 "6""）
+- ✅ 时间戳（自动插入，5 分钟间隔）
+- ✅ 打字机效果支持
+- ✅ 自动滚动到底部
+
+---
+
+## 📁 创建的文件清单
+
+### 1. Model（数据模型）
+```
+keyBoard/Class/AiTalk/M/
+├── KBChatMessage.h          # 消息模型头文件
+└── KBChatMessage.m          # 消息模型实现
+```
+
+**功能：**
+- 支持三种消息类型：用户、AI、时间戳
+- 包含文本、时间戳、语音时长、语音数据等属性
+- 提供便捷构造方法
+
+---
+
+### 2. View（视图组件）
+```

+└── V/
+    ├── KBChatTableView_Usage.md    # 使用说明
+    └── API_快速参考.md             # API 快速查询
+```
+
+---
+
+## 🏗️ 架构设计
+
+### 方案选择：UITableView + Plain 模式
+
+**为什么选择 Plain 模式？**
+
+| 对比项 | Plain 模式 ✅ | Grouped 模式 ❌ |
+|--------|--------------|----------------|
+| 视觉连贯性 | 消息紧密排列 | Section 间距打断视觉 |
+| 时间戳处理 | 作为普通 Cell 灵活插入 | 需要用 Section Header |
+| 数据管理 | 一维数组，简单 | 二维数组，复杂 |
+| 性能 | Cell 复用简单 | Section 管理开销 |
+| 符合习惯 | 微信、iMessage 都用此方案 | 不适合聊天场景 |
+
+### 三种独立 Cell 设计
+
+**为什么不用一个通用 Cell？**
+
+✅ **三种独立 Cell 的优势：**
+- 职责清晰，每个 Cell 只负责一种样式
+- 布局简单，不需要复杂的条件判断
+- 复用标识符明确，性能好
+- 易于维护和扩展
+
+❌ **通用 Cell 的劣势：**
+- Cell 内部逻辑复杂，大量 if-else
+- 布局约束需要动态调整，容易出错
+- 复用时需要重置状态，性能略差
+
+---
+
+## 🎯 核心实现细节
+
+### 1. 时间戳自动插入
+
+**策略：**
+- 第一条消息总是显示时间
+- 距离上一条消息超过 5 分钟
+- 跨天的消息
+
+**实现：**
+```objective-c
+- (BOOL)shouldInsertTimestampForMessage:(KBChatMessage *)message {
+    if (self.messages.count == 0) return YES;
+    
+    KBChatMessage *lastMessage = [self findLastNonTimeMessage];
+    NSTimeInterval interval = [message.timestamp timeIntervalSinceDate:lastMessage.timestamp];
+    
+    if (interval >= kTimestampInterval) return YES;
+    
+    // 检查是否跨天
+    return ![self isSameDay:message.timestamp with:lastMessage.timestamp];
+}
+```
+
+---
+
+### 2. 语音播放管理
+
+**功能：**
+- 点击播放/暂停
+- 播放时图标切换
+- 点击其他消息自动停止当前播放
+- 播放完成自动恢复
+
+**实现：**
+```objective-c
+- (void)assistantMessageCell:(KBChatAssistantMessageCell *)cell
+    didTapVoiceButtonForMessage:(KBChatMessage *)message {
+    
+    NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
+    
+    // 如果正在播放同一条，则暂停
+    if ([indexPath isEqual:self.playingCellIndexPath]) {
+        [self stopPlayingAudio];
+        return;
+    }
+    
+    // 停止之前的播放
+    [self stopPlayingAudio];
+    
+    // 播放新的音频
+    [self playAudioForMessage:message atIndexPath:indexPath];
+}
+```
+
+---
+
+### 3. 打字机效果
+
+**流程：**
+1. 添加空消息占位
+2. 逐步更新文本
+3. 标记完成
+
+**实现：**
+```objective-c
+// 1. 添加占位
+[self.chatView addAssistantMessage:@"" audioDuration:0 audioData:nil];
+
+// 2. 更新文本
+[self.chatView updateLastAssistantMessage:currentText];
+
+// 3. 完成
+[self.chatView markLastAssistantMessageComplete];
+```
+
+---
+
+### 4. 自动滚动
+
+**策略：**
+- 新消息添加后自动滚动到底部
+- 使用动画效果
+- 延迟 0.1 秒确保布局完成
+
+**实现：**
+```objective-c
+- (void)reloadAndScroll {
+    [self.tableView reloadData];
+    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.1 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
+        [self scrollToBottom];
+    });
+}
+```
+
+---
+
+## 📊 数据流
+
+```
+用户输入
+    ↓
+KBChatMessage (用户消息)
+    ↓
+判断是否需要时间戳
+    ↓
+插入时间戳 Cell（可选）

+// 3. 用户点击语音按钮时异步加载音频
+```
+
+---
+
+## 🎯 核心实现
+
+### 1. 点击语音按钮的处理逻辑
+
+```objective-c
+- (void)assistantMessageCell:(KBChatAssistantMessageCell *)cell
+    didTapVoiceButtonForMessage:(KBChatMessage *)message {
+    
+    // 如果有 audioData，直接播放
+    if (message.audioData && message.audioData.length > 0) {
+        [self playAudioForMessage:message atIndexPath:indexPath];
+        return;
+    }
+    
+    // 如果有 audioId，异步加载音频
+    if (message.audioId.length > 0) {
+        [self loadAndPlayAudioForMessage:message atIndexPath:indexPath];
+        return;
+    }
+}
+```
+
+---
+
+### 2. 异步加载音频
+
+```objective-c
+- (void)loadAndPlayAudioForMessage:(KBChatMessage *)message atIndexPath:(NSIndexPath *)indexPath {
+    // 1. 开始等待效果（显示播放中状态）
+    [self startWaitingForCell:indexPath];

+    [self.aiVM requestAudioWithAudioId:message.audioId
+                            completion:^(NSString *audioURL, NSError *error) {
+        // 3. 停止等待效果
+        [self stopWaitingForCell:indexPath];
+        
+        if (error) {
+            NSLog(@"加载音频失败");
+            return;
+        }
+        
+        // 4. 下载音频数据
+        [self downloadAndPlayAudioFromURL:audioURL

+                             atIndexPath:indexPath];
+    }];
+}
+```
+
+---
+
+### 3. 等待效果（3秒超时）
+
+```objective-c
+- (void)startWaitingForCell:(NSIndexPath *)indexPath {
+    self.waitingCellIndexPath = indexPath;
+    
+    // 更新 Cell 为等待状态（显示播放中图标）
+    KBChatAssistantMessageCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];

+
+- (void)waitingTimeout {
+    NSLog(@"音频加载超时");
+    [self stopWaitingForCell:self.waitingCellIndexPath];
+}
+```
+
+---
+
+### 4. 音频缓存
+
+```objective-c
+- (void)downloadAndPlayAudioFromURL:(NSString *)urlString
+                         forMessage:(KBChatMessage *)message
+                        atIndexPath:(NSIndexPath *)indexPath {
+    // 下载音频
+    NSURLSessionDataTask *task = [session dataTaskWithURL:url
+                                        completionHandler:^(NSData *data, ...) {
+        // 缓存到消息对象
+        message.audioData = data;
+        
+        // 计算时长
+        AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:data error:nil];
+        message.audioDuration = player.duration;
+        
+        // 刷新 Cell
+        [self.tableView reloadRowsAtIndexPaths:@[indexPath] ...];
+        
+        // 播放音频
+        [self playAudioForMessage:message atIndexPath:indexPath];
+    }];
+    [task resume];
+}
+```
+
+---
+
+## 📊 数据结构
+
+### chat/message 接口返回
+```json
+{
+  "code": 0,
+  "message": "ok",
+  "data": {
+    "aiResponse": "Ugh, seriously? It's Tiffany...",
+    "audioId": "6e3e90575ce04658ab6c45d77a506100",
+    "llmDuration": 1572
+  }
+}
+```
+
+### /chat/audio/{audioId} 接口返回
+```json
+{
+  "code": 0,
+  "data": {
+    "url": "http://127.0.0.1:4523/m1/7401033-7133645-default/chat/audio/1"
+  }
+}
+```
+
+---
+

+# 类名冲突解决说明
+
+## 🐛 问题
+
+在实现新的聊天 UI 时，创建了 `KBChatMessage` 类，但与 `CustomKeyboard` 目录下已有的 `KBChatMessage` 类产生了命名冲突，导致 `KeyboardViewController` 编译报错：
+
+```
+Property 'audioFilePath' not found on object of type 'KBChatMessage *'
+```
+
+---
+
+## 🔍 原因分析
+
+项目中存在两个同名的 `KBChatMessage` 类：
+
+### 1. CustomKeyboard/Model/KBChatMessage（旧的）
+```objective-c
+@interface KBChatMessage : NSObject
+@property (nonatomic, copy) NSString *text;
+@property (nonatomic, assign) BOOL outgoing;
+@property (nonatomic, copy, nullable) NSString *audioFilePath;  // ← 旧的属性
+@property (nonatomic, copy, nullable) NSString *avatarURL;
+@property (nonatomic, copy, nullable) NSString *displayName;
+@property (nonatomic, strong, nullable) UIImage *avatarImage;
+@end
+```
+
+**用途：** 键盘扩展（CustomKeyboard）中的聊天消息模型
+
+---
+
+### 2. keyBoard/Class/AiTalk/M/KBChatMessage（新的）
+```objective-c
+@interface KBChatMessage : NSObject
+@property (nonatomic, assign) KBChatMessageType type;
+@property (nonatomic, copy) NSString *text;
+@property (nonatomic, strong) NSDate *timestamp;
+@property (nonatomic, assign) NSTimeInterval audioDuration;
+@property (nonatomic, strong, nullable) NSData *audioData;      // ← 新的属性
+@property (nonatomic, copy, nullable) NSString *audioId;        // ← 新的属性
+@property (nonatomic, assign) BOOL isComplete;
+@end
+```
+
+**用途：** AI 聊天主界面（KBAiMainVC）中的消息模型
+
+---
+
+## ✅ 解决方案
+
+将新创建的类重命名为 `KBAiChatMessage`，避免与旧类冲突。
+
+---
+
+## 📝 修改清单
+
+### 1. 重命名类文件
+- `KBChatMessage.h` → `KBAiChatMessage.h`
+- `KBChatMessage.m` → `KBAiChatMessage.m`
+
+### 2. 重命名类名
+```objective-c
+// 原来
+@interface KBChatMessage : NSObject
+
+// 修改为
+@interface KBAiChatMessage : NSObject
+```
+
+### 3. 重命名枚举
+```objective-c
+// 原来
+typedef NS_ENUM(NSInteger, KBChatMessageType) {
+    KBChatMessageTypeUser,
+    KBChatMessageTypeAssistant,
+    KBChatMessageTypeTime
+};
+
+// 修改为
+typedef NS_ENUM(NSInteger, KBAiChatMessageType) {
+    KBAiChatMessageTypeUser,
+    KBAiChatMessageTypeAssistant,
+    KBAiChatMessageTypeTime
+};
+```
+
+### 4. 更新所有引用
+
+#### Cell 文件
+- `KBChatUserMessageCell.h/m`
+- `KBChatAssistantMessageCell.h/m`
+- `KBChatTimeCell.h/m`
+
+#### 视图文件
+- `KBChatTableView.h/m`
+
+#### 所有方法参数和属性
+```objective-c
+// 原来
+- (void)configureWithMessage:(KBChatMessage *)message;
+@property (nonatomic, strong) NSMutableArray<KBChatMessage *> *messages;
+
+// 修改为
+- (void)configureWithMessage:(KBAiChatMessage *)message;
+@property (nonatomic, strong) NSMutableArray<KBAiChatMessage *> *messages;
+```
+
+---
+
+## 📊 最终结构
+
+### CustomKeyboard（键盘扩展）
+```
+CustomKeyboard/Model/
+├── KBChatMessage.h          ← 旧的，保持不变
+└── KBChatMessage.m
+```
+
+**用途：** 键盘扩展中的聊天功能
+
+---
+
+### AiTalk（AI 聊天主界面）
+```
+keyBoard/Class/AiTalk/M/
+├── KBAiChatMessage.h        ← 新的，已重命名
+└── KBAiChatMessage.m
+```
+
+**用途：** AI 聊天主界面的消息模型
+
+---
+
+## ✅ 验证
+
+编译项目，确认：
+- ✅ `KeyboardViewController` 不再报错
+- ✅ `KBAiMainVC` 正常工作
+- ✅ 两个模块互不干扰
+
+---
+
+## 🎯 总结
+
+通过将新类重命名为 `KBAiChatMessage`，成功解决了类名冲突问题。现在：
+
+- **CustomKeyboard** 使用 `KBChatMessage`（旧的）
+- **AiTalk** 使用 `KBAiChatMessage`（新的）
+
+两者各司其职，互不干扰！✅

+## 🔧 集成到 KBAiMainVC
+
+### 步骤 1：修改 import
+
+在 `KBAiMainVC.m` 顶部添加：
+
+```objective-c
+#import "KBChatTableView.h"
+```
+
+### 步骤 2：修改属性声明
+
+将：
+```objective-c
+@property (nonatomic, strong) KBAiChatView *chatView;
+```
+
+改为：
+```objective-c
+@property (nonatomic, strong) KBChatTableView *chatView;
+```
+
+### 步骤 3：修改 setupUI 方法
+
+将：
+```objective-c
+self.chatView = [[KBAiChatView alloc] init];
+```
+
+改为：
+```objective-c
+self.chatView = [[KBChatTableView alloc] init];
+```
+
+### 步骤 4：修改消息添加逻辑
+
+#### 添加用户消息（保持不变）
+```objective-c
+[self.chatView addUserMessage:finalText];
+```
+
+#### 添加 AI 消息（需要修改）
+
+**原来的代码：**
+```objective-c
+[self.chatView addAssistantMessage:polishedText];
+[self.chatView markLastAssistantMessageComplete];
+```
+
+**新的代码：**
+```objective-c
+// 计算音频时长（如果有音频数据）
+NSTimeInterval duration = 0;
+if (audioData && audioData.length > 0) {
+    // 方法 1：从 AVAudioPlayer 获取准确时长
+    NSError *error = nil;
+    AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:audioData error:&error];
+    if (!error && player) {
+        duration = player.duration;
+    }
+    
+    // 方法 2：估算时长（如果知道采样率）
+    // duration = audioData.length / (sampleRate * channels * bytesPerSample);
+}
+
+[self.chatView addAssistantMessage:polishedText
+                     audioDuration:duration
+                         audioData:audioData];
+```
+
+### 步骤 5：修改打字机效果（如果使用）
+
+**原来的代码：**
+```objective-c
+[self.chatView addAssistantMessage:@""];
+[self.chatView updateLastAssistantMessage:token];
+[self.chatView markLastAssistantMessageComplete];
+```
+
+**新的代码：**
+```objective-c
+// 1. 添加空消息占位
+[self.chatView addAssistantMessage:@""
+                     audioDuration:0
+                         audioData:nil];
+
+// 2. 逐步更新
+[self.chatView updateLastAssistantMessage:token];
+
+// 3. 完成后标记并添加音频
+[self.chatView markLastAssistantMessageComplete];
+
+// 如果有音频，需要更新最后一条消息的音频数据
+// 注意：当前实现不支持后续添加音频，建议在完成时重新添加消息
+```

+
+## 🧪 测试步骤
+
+### 1. 测试新 UI（使用测试页面）
+
+在任意地方跳转到测试页面：
+
+```objective-c
+KBChatTestVC *testVC = [[KBChatTestVC alloc] init];
+[self.navigationController pushViewController:testVC animated:YES];
+```
+
+### 2. 集成到 KBAiMainVC
+
+按照上面的步骤修改 `KBAiMainVC.m`
+
+### 3. 验证功能
+
+- ✅ 用户消息显示在右侧
+- ✅ AI 消息显示在左侧
+- ✅ 时间戳自动插入
+- ✅ 语音按钮可点击播放
+- ✅ 语音时长正确显示
+- ✅ 消息自动滚动到底部
+
+---
+
+## 🎨 自定义样式
+
+### 修改气泡颜色
+
+**用户消息**（`KBChatUserMessageCell.m`）：
+```objective-c
+self.bubbleView.backgroundColor = [UIColor colorWithRed:0.94 green:0.94 blue:0.94 alpha:1.0];
+self.messageLabel.textColor = [UIColor blackColor];
+```
+
+**AI 消息**（`KBChatAssistantMessageCell.m`）：
+```objective-c
+self.bubbleView.backgroundColor = [UIColor colorWithRed:0.2 green:0.2 blue:0.2 alpha:0.7];
+self.messageLabel.textColor = [UIColor whiteColor];
+```
+
+### 修改时间戳间隔
+
+在 `KBChatTableView.m` 中：
+```objective-c
+static const NSTimeInterval kTimestampInterval = 5 * 60; // 改为你想要的秒数
+```
+
+### 修改气泡圆角
+
+在对应的 Cell 中：
+```objective-c
+self.bubbleView.layer.cornerRadius = 16; // 改为你想要的值
+```
+
+---
+
+## ⚠️ 注意事项
+
+1. **音频格式**：确保 `audioData` 是 AVAudioPlayer 支持的格式（MP3、AAC、M4A 等）
+
+2. **音频会话**：播放音频前确保配置了 AVAudioSession（已在 `AudioSessionManager` 中处理）
+
+3. **内存管理**：如果消息量很大，考虑：
+   - 限制消息数量（如只保留最近 100 条）
+   - 清除旧消息的音频数据
+   - 实现分页加载
+
+4. **线程安全**：所有 UI 更新必须在主线程执行
+
+5. **音频时长计算**：
+   - 方法 1：使用 AVAudioPlayer 获取准确时长（推荐）
+   - 方法 2：根据采样率估算（不够准确）
+
+---
+
+## 🐛 常见问题
+
+### Q1: 语音按钮不显示？
+**A:** 检查 `audioData` 是否为 nil 或长度为 0
+
+### Q2: 点击语音按钮没反应？
+**A:** 检查音频数据格式是否正确，查看控制台日志
+
+### Q3: 时间戳不显示？
+**A:** 检查消息的 `timestamp` 是否正确设置
+
+### Q4: 消息不自动滚动？
+**A:** 确保在主线程调用 `scrollToBottom`
+
+### Q5: 气泡宽度不对？
+**A:** 检查 Masonry 约束，确保 `multipliedBy(0.75)` 生效
