# 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`
---
## 🎯 完整示例
```objective-c
// 1. 用户发送消息
[self.chatView addUserMessage:@"你好"];
// 2. AI 回复(带语音)
NSString *aiText = @"你好!很高兴见到你。";
NSData *audioData = ...; // 从 TTS 获取
NSError *error = nil;
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:audioData error:&error];
NSTimeInterval duration = player ? player.duration : 0;
[self.chatView addAssistantMessage:aiText
audioDuration:duration
audioData:audioData];
// 3. 打字机效果
[self.chatView addAssistantMessage:@"" audioDuration:0 audioData:nil];
// 模拟流式返回
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.1 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[self.chatView updateLastAssistantMessage:@"正"];
});
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.2 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[self.chatView updateLastAssistantMessage:@"正在"];
});
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.3 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[self.chatView updateLastAssistantMessage:@"正在思考"];
});
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.4 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[self.chatView updateLastAssistantMessage:@"正在思考..."];
[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];
```
---
## ⚠️ 注意事项
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

## ✅ 测试清单
- [ ] 用户消息显示在右侧
- [ ] AI 消息显示在左侧
- [ ] 语音按钮显示在 AI 消息左上角
- [ ] 点击语音按钮可播放
- [ ] 语音时长正确显示
- [ ] 时间戳自动插入
- [ ] 消息从底部向上显示
- [ ] 新消息自动滚动到底部
- [ ] 打字机效果正常工作
- [ ] 语音播放状态图标切换
---
## 🐛 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
✅ 用户消息在右侧
✅ AI 消息在左侧(带语音按钮)
✅ 时间戳自动插入
✅ 语音播放功能
✅ 打字机效果
运行项目即可看到效果!

---
## 📁 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
```

## 🏗️ 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
插入用户消息 Cell
刷新 TableView
滚动到底部
AI 处理
KBChatMessage (AI 消息 + 音频)
判断是否需要时间戳
插入时间戳 Cell可选
插入 AI 消息 Cell
刷新 TableView
滚动到底部

### 时间戳(居中)
```
16:36
```

// 4. 播放音频
// 现在:
// 1. 请求 chat/message返回 audioId
// 2. 添加消息(带 audioId
// 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];
// 2. 请求音频 URL
[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
forMessage:message
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];
[cell updateVoicePlayingState:YES];
// 3 秒后自动停止
self.waitingTimer = [NSTimer scheduledTimerWithTimeInterval:3.0
target:self
selector:@selector(waitingTimeout)
userInfo:nil
repeats:NO];
}
- (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"
}
}
```
---
## ✅ 优势
1. **后端统一处理 TTS**:不需要前端配置 ElevenLabs API Key
2. **异步加载**:不阻塞 UI用户体验更好
3. **音频缓存**:下载后缓存,再次点击直接播放
4. **等待效果**3秒超时保护避免无限等待
5. **降低耦合**:前端不需要关心 TTS 实现细节

# 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
---
### AiTalkAI 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
`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
```
---
## 📝 完整示例:修改 deepgramStreamingManagerDidReceiveFinalTranscript
```objective-c
- (void)deepgramStreamingManagerDidReceiveFinalTranscript:(NSString *)text {
if (text.length > 0) {
if (self.deepgramFullText.length > 0) {
[self.deepgramFullText appendString:@" "];
}
[self.deepgramFullText appendString:text];
}
self.transcriptLabel.text = self.deepgramFullText;
self.statusLabel.text = @"识别完成";
self.recordButton.state = KBAiRecordButtonStateNormal;
NSString *finalText = [self.deepgramFullText copy];
if (finalText.length == 0) {
return;
}
// 添加用户消息
[self.chatView addUserMessage:finalText];
if (self.elevenLabsApiKey.length == 0 || self.elevenLabsVoiceId.length == 0) {
[KBHUD showError:@"请先配置 ElevenLabs API Key/VoiceId"];
return;
}
__weak typeof(self) weakSelf = self;
[KBHUD showWithStatus:@"润色中..."];
[self.aiVM requestChatMessageWithContent:finalText
completion:^(KBAiMessageResponse *_Nullable response,
NSError *_Nullable error) {
__strong typeof(weakSelf) strongSelf = weakSelf;
if (!strongSelf) return;
dispatch_async(dispatch_get_main_queue(), ^{
if (error) {
[KBHUD dismiss];
[KBHUD showError:error.localizedDescription ?: @"润色失败"];
return;
}
NSString *polishedText = response.data.content ?: response.data.text ?: response.data.message ?: @"";
if (polishedText.length == 0) {
[KBHUD dismiss];
[KBHUD showError:@"润色结果为空"];
return;
}
[KBHUD showWithStatus:@"生成语音..."];
[strongSelf.aiVM requestElevenLabsSpeechWithText:polishedText
voiceId:strongSelf.elevenLabsVoiceId
apiKey:strongSelf.elevenLabsApiKey
outputFormat:nil
modelId:nil
completion:^(NSData *_Nullable audioData,
NSError *_Nullable ttsError) {
dispatch_async(dispatch_get_main_queue(), ^{
[KBHUD dismiss];
if (ttsError) {
[KBHUD showError:ttsError.localizedDescription ?: @"语音生成失败"];
// 即使语音失败,也添加文本消息
[strongSelf.chatView addAssistantMessage:polishedText
audioDuration:0
audioData:nil];
return;
}
// 计算音频时长
NSTimeInterval duration = 0;
if (audioData && audioData.length > 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)
[strongSelf.chatView addAssistantMessage:polishedText
audioDuration:duration
audioData:audioData];
});
}];
});
}];
}
```

## 🎨 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
