+## 🌐 接口说明
+
+### 接口地址
+```
+POST /chat/history
+```
+
+### 请求参数
+```json
+{
+  "companionId": 0,  // AI 陪聊角色 ID（使用 KBPersonaModel.personaId）
+  "pageNum": 1,      // 页码
+  "pageSize": 20     // 每页大小
+}
+```
+
+### 参数说明
+- **companionId**：使用 `fetchPersonasWithPageNum` 接口返回的 `KBPersonaModel.personaId`
+- **pageNum**：页码，从 1 开始
+- **pageSize**：每页大小，建议 20
+
+### 响应格式
+```json
+{
+  "code": 0,
+  "message": "success",
+  "data": {
+    "records": [
+      {
+        "id": 1,

+      }
+    ],
+    "total": 100,
+    "current": 1,
+    "pages": 5
+  }
+}
+```
+
+---
+
+## 📝 使用示例
+
+### 1. 在 AiVM 中调用接口
+
+```objc
+#import "AiVM.h"
+
+AiVM *aiVM = [[AiVM alloc] init];
+
+[aiVM fetchChatHistoryWithCompanionId:123
+                               pageNum:1
+                              pageSize:20
+                            completion:^(KBChatHistoryPageModel *pageModel, NSError *error) {
+    if (error) {
+        NSLog(@"加载失败：%@", error.localizedDescription);
+        return;
+    }
+    
+    NSLog(@"加载成功：%ld 条消息", pageModel.records.count);
+    
+    for (KBChatHistoryModel *message in pageModel.records) {
+        if (message.isUserMessage) {
+            NSLog(@"用户：%@", message.content);
+        } else {
+            NSLog(@"AI：%@", message.content);
+        }
+    }
+    
+    if (pageModel.hasMore) {
+        NSLog(@"还有更多数据");
+    }
+}];
+```
+
+### 2. 在 VC 中使用
+
+```objc
+@interface YourViewController ()
+@property (nonatomic, strong) AiVM *aiVM;
+@property (nonatomic, strong) NSMutableArray<KBChatHistoryModel *> *messages;
+@property (nonatomic, assign) NSInteger currentPage;
+@property (nonatomic, assign) BOOL hasMore;
+@end
+
+@implementation YourViewController
+
+- (void)viewDidLoad {
+    [super viewDidLoad];
+    self.aiVM = [[AiVM alloc] init];
+    self.messages = [NSMutableArray array];
+    self.currentPage = 1;
+    self.hasMore = YES;
+    
+    [self loadChatHistory];
+}
+
+- (void)loadChatHistory {
+    NSInteger companionId = 123; // 当前人设 ID
+    
+    __weak typeof(self) weakSelf = self;
+    [self.aiVM fetchChatHistoryWithCompanionId:companionId
+                                        pageNum:self.currentPage
+                                       pageSize:20
+                                     completion:^(KBChatHistoryPageModel *pageModel, NSError *error) {
+        if (error) {
+            NSLog(@"加载失败：%@", error.localizedDescription);
+            return;
+        }
+        
+        // 追加数据
+        [weakSelf.messages addObjectsFromArray:pageModel.records];
+        weakSelf.hasMore = pageModel.hasMore;
+        
+        // 刷新 UI
+        [weakSelf.tableView reloadData];
+    }];
+}
+
+- (void)loadMoreHistory {
+    if (!self.hasMore) {
+        return;
+    }
+    
+    self.currentPage++;
+    [self loadChatHistory];
+}
+
+@end
+```
+
+### 3. 转换为 KBAiChatMessage
+
+```objc
+// 将 KBChatHistoryModel 转换为 KBAiChatMessage（用于聊天界面展示）
+- (KBAiChatMessage *)convertToAiChatMessage:(KBChatHistoryModel *)historyModel {
+    if (historyModel.isUserMessage) {
+        return [KBAiChatMessage userMessageWithText:historyModel.content];
+    } else {
+        return [KBAiChatMessage assistantMessageWithText:historyModel.content];
+    }
+}
+
+// 批量转换
+- (NSArray<KBAiChatMessage *> *)convertHistoryToMessages:(NSArray<KBChatHistoryModel *> *)history {
+    NSMutableArray *messages = [NSMutableArray array];
+    for (KBChatHistoryModel *item in history) {
+        [messages addObject:[self convertToAiChatMessage:item]];
+    }
+    return messages;
+}
+```
+
+---
+
+## 🔄 与 KBPersonaChatCell 集成
+
+### 在 KBPersonaChatCell 中加载聊天记录
+
+```objc
+// KBPersonaChatCell.m
+
+- (void)setPersona:(KBPersonaModel *)persona {
+    _persona = persona;

+    CGFloat offsetY = scrollView.contentOffset.y;
+    
+    if (offsetY <= -50 && !self.isLoading) {
+        [self loadMoreHistory];
+    }
+}
+```
+
+---
+
+## 📊 数据流程
+
+```
+1. 用户滑动到某个人设
+   ↓
+2. KBPersonaChatCell 触发预加载
+   ↓
+3. 调用 AiVM.fetchChatHistoryWithCompanionId
+   ↓
+4. 请求 POST /chat/history
+   ↓
+5. 返回 KBChatHistoryPageModel
+   ↓
+6. 转换为 KBAiChatMessage
+   ↓
+7. 在 TableView 中展示
+```
+
+---
+
+## 🎯 字段映射
+
+### MJExtension 自动映射
+
+| JSON 字段 | Model 属性 | 说明 |
+|-----------|-----------|------|
+| `id` | `messageId` | 消息 ID |
+| `sender` | `sender` | 发送者（0-用户，1-AI） |
+| `content` | `content` | 消息内容 |
+| `createdAt` | `createdAt` | 创建时间 |
+
+### 枚举值说明
+
+```objc
+typedef NS_ENUM(NSInteger, KBChatSender) {
+    KBChatSenderUser = 0,      // 用户
+    KBChatSenderAssistant = 1  // AI 助手
+};
+```
+
+---
+
+## ✅ 已完成功能
+
+1. ✅ KBChatHistoryModel：聊天记录模型
+2. ✅ KBChatHistoryPageModel：分页数据模型
+3. ✅ AiVM 新增接口：fetchChatHistoryWithCompanionId
+4. ✅ MJExtension 配置：JSON 自动转 Model
+5. ✅ 扩展属性：isUserMessage、isAssistantMessage、hasMore
+6. ✅ 容错处理：字段为 null 时设置默认值
+
+---
+
+## 🚧 待实现功能
+
+1. 在 KBPersonaChatCell 中集成聊天记录加载
+2. 实现下拉加载更多历史消息
+3. 实现消息时间戳显示
+4. 实现消息发送功能
+5. 实现消息缓存（避免重复请求）
+
+---
+
+## 📌 注意事项
+
+1. **companionId**：直接使用 `KBPersonaModel.personaId`（人设列表接口返回的 ID）
+2. **时间格式**：createdAt 是字符串，需要根据实际格式解析
+3. **分页方向**：默认从最新消息开始加载，下拉加载历史消息
+4. **消息顺序**：需要根据实际需求决定是正序还是倒序
+5. **容错处理**：已做 null 值容错，确保不会崩溃
+
+### 数据关联关系
+
+```
+KBPersonaModel (人设列表)
+  └─ personaId (人设 ID)
+       ↓
+  用作 companionId 参数
+       ↓
+KBChatHistoryPageModel (聊天记录)
+  └─ records (消息列表)
+```

+# KBVoiceInputBar 使用说明
+
+## 📦 组件概述
+
+`KBVoiceInputBar` 是一个封装好的底部语音输入栏组件，包含：
+- ✅ 毛玻璃背景（带渐变 mask）
+- ✅ 状态标签（显示当前状态）
+- ✅ 录音按钮（支持长按、波形动画）
+- ✅ 代理回调（开始/结束/取消录音）
+
+---
+
+## 🎨 UI 结构
+
+```
+┌─────────────────────────────┐
+│  毛玻璃背景（渐变透明）        │
+│  ┌─────────────────────┐    │
+│  │   状态标签           │    │
+│  │  "按住按钮开始对话"   │    │
+│  └─────────────────────┘    │
+│  ┌─────────────────────┐    │
+│  │   录音按钮           │    │
+│  │  [按住说话]          │    │
+│  └─────────────────────┘    │
+└─────────────────────────────┘
+```
+
+---
+
+## 📝 使用方式
+
+### 1. 导入头文件
+
+```objc
+#import "KBVoiceInputBar.h"
+```
+
+### 2. 在 VC 中声明属性
+
+```objc
+@interface YourViewController () <KBVoiceInputBarDelegate>
+@property (nonatomic, strong) KBVoiceInputBar *voiceInputBar;
+@end
+```
+
+### 3. 初始化和布局
+
+```objc
+- (void)setupUI {
+    // 创建语音输入栏
+    self.voiceInputBar = [[KBVoiceInputBar alloc] init];
+    self.voiceInputBar.delegate = self;
+    self.voiceInputBar.statusText = @"按住按钮开始对话";
+    
+    [self.view addSubview:self.voiceInputBar];
+    [self.voiceInputBar mas_makeConstraints:^(MASConstraintMaker *make) {
+        make.left.right.equalTo(self.view);
+        make.bottom.equalTo(self.view);
+        make.height.mas_equalTo(150); // 根据实际需要调整
+    }];
+}
+```
+
+### 4. 实现代理方法
+
+```objc
+#pragma mark - KBVoiceInputBarDelegate
+
+- (void)voiceInputBarDidBeginRecording:(KBVoiceInputBar *)inputBar {
+    NSLog(@"开始录音");
+    inputBar.statusText = @"正在聆听...";
+    
+    // TODO: 开始录音逻辑
+    // 1. 检查登录状态
+    // 2. 连接语音识别服务
+    // 3. 开始录音
+}
+
+- (void)voiceInputBarDidEndRecording:(KBVoiceInputBar *)inputBar {
+    NSLog(@"结束录音");
+    inputBar.statusText = @"正在识别...";
+    
+    // TODO: 结束录音逻辑
+    // 1. 停止录音
+    // 2. 发送音频数据
+    // 3. 等待识别结果
+}
+
+- (void)voiceInputBarDidCancelRecording:(KBVoiceInputBar *)inputBar {
+    NSLog(@"取消录音");
+    inputBar.statusText = @"已取消";
+    
+    // TODO: 取消录音逻辑
+    // 1. 停止录音
+    // 2. 清理资源
+}
+```
+
+---
+

+
+// AI 思考中
+self.voiceInputBar.statusText = @"AI 正在思考...";
+
+// 完成
+self.voiceInputBar.statusText = @"完成";
+```
+
+### 示例 2：更新音量波形
+
+```objc
+// 在录音过程中，定时更新音量
+- (void)onVolumeUpdate:(float)rms {
+    [self.voiceInputBar updateVolumeRMS:rms];
+}
+```
+
+### 示例 3：禁用/启用按钮
+
+```objc
+// 禁用（比如未登录时）
+self.voiceInputBar.enabled = NO;
+
+// 启用
+self.voiceInputBar.enabled = YES;
+```
+
+### 示例 4：手动设置录音状态
+
+```objc
+// 开始录音
+[self.voiceInputBar setRecording:YES];
+
+// 结束录音
+[self.voiceInputBar setRecording:NO];
+```

+```
+

+
+## 🎨 自定义样式
+
+### 修改毛玻璃效果
+
+```objc
+// 在 KBVoiceInputBar.m 中修改
+UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark]; // 改为深色
+```
+
+### 修改按钮样式
+
+```objc
+// 在 KBVoiceInputBar.m 的 recordButton 懒加载中修改
+_recordButton.normalTitle = @"点击说话";
+_recordButton.recordingTitle = @"正在录音...";
+_recordButton.tintColor = [UIColor systemBlueColor];
+```
+
+### 修改高度
+
+```objc
+// 在布局时调整
+[self.voiceInputBar mas_makeConstraints:^(MASConstraintMaker *make) {
+    make.height.mas_equalTo(200); // 调整为 200
+}];
+```
+
+---
+
+## 📌 注意事项
+
+1. **代理必须设置**：否则无法接收录音事件
+2. **高度建议**：推荐高度 150-200，根据实际需要调整
+3. **状态文本**：及时更新 `statusText` 提升用户体验
+4. **音量更新**：定时调用 `updateVolumeRMS:` 显示波形动画
+5. **禁用状态**：未登录或其他情况下记得禁用按钮
+
+---
+
+## 🚀 优势
+
+1. ✅ **开箱即用**：无需关心内部实现细节
+2. ✅ **高度封装**：毛玻璃背景、按钮、状态标签一体化
+3. ✅ **易于集成**：只需实现 3 个代理方法
+4. ✅ **样式统一**：与 KBAiMainVC 保持一致
+5. ✅ **易于扩展**：可以轻松添加更多功能
