你是一个友好、专业的语音助手，名叫"小语"。你的目标是通过对话为用户提供帮助、解答问题和完成任务。 |
|||
遵循以下指导原则： |
|||
1. 保持简短精炼的回答，因为用户是通过语音与你交流 |
|||
2. 优先使用中文回复，除非用户明确要求使用其他语言 |
|||
3. 当用户问题不明确时，礼貌地请求更多信息 |
|||
4. 避免过长的列表，尽量将信息分成小段 |
|||
5. 不要使用需要视觉展示的元素（如表格、图表或代码块） |
|||
6. 记住用户之前的对话内容，保持对话连贯 |
|||
7. 如果用户发送了图片，请根据图片内容和文字要求回答问题 |
|||
你不仅可以回答知识性问题，还可以帮助用户设置提醒、提供建议，或进行轻松愉快的对话。 |

无论遇到什么问题，都要尽力以温暖、贴心的语气提供最佳帮助。 |

# Chat Storage 插件 - iOS 实现 |
|||
|
|||
## 概述 |
|||
|
|||
Chat Storage 插件的 iOS 实现，为 Flutter 应用提供本地 SQLite 数据库支持，用于存储和管理聊天记录。 |
|||
|
|||
## 功能特性 |
|||
|
|||
- 基于 SQLite 的聊天记录存储 |
|||
- 支持按会话分组消息 |
|||
- 提供分页查询功能 |
|||
- 支持元数据存储 |
|||
- 完整的增删改查 API |
|||
|
|||
## 技术实现 |
|||
|
|||
本插件使用原生 Swift 实现，通过 SQLite C API 直接操作数据库，不依赖第三方 SQLite 封装库，以保持最小的依赖要求和最佳性能。 |
|||
|
|||
### 核心组件 |
|||
|
|||
- `ChatStorageHelper`: 负责 SQLite 数据库操作，提供完整的数据操作 API |
|||
- `ChatStoragePlugin`: 插件主类，处理与 Flutter 的通信 |
|||
|
|||
### 数据库结构 |
|||
|
|||
数据库包含一个 `messages` 表，结构如下： |
|||
|
|||
```sql |
|||
CREATE TABLE messages ( |
|||
id INTEGER PRIMARY KEY AUTOINCREMENT, |
|||
session_id TEXT NOT NULL, |
|||
message TEXT NOT NULL, |
|||
sender TEXT NOT NULL, |
|||
timestamp TEXT NOT NULL, |
|||
metadata TEXT |
|||
); |
|||
|
|||
-- 索引 |
|||
CREATE INDEX idx_session_id ON messages (session_id); |
|||
CREATE INDEX idx_timestamp ON messages (timestamp); |
|||
``` |
|||
|
|||
## 使用注意事项 |
|||
|
|||
### SQLite 多线程访问 |
|||
|
|||
本插件所有数据库操作均在主线程执行，以避免 SQLite 多线程访问的复杂性。在处理大量数据时，建议在 Flutter 层面使用 `compute` 函数或 `Isolate` 进行异步处理。 |
|||
|
|||
### 数据格式 |
|||
|
|||
- 时间戳使用 `yyyy-MM-dd HH:mm:ss` 格式的字符串 |
|||
- JSON 转换遵循 Swift/Objective-C 的类型映射规则 |
|||
|
|||
## 调试与故障排除 |
|||
|
|||
- 日志前缀为 `ChatStoragePlugin` 和 `ChatStorageHelper` |
|||
- 可通过 Console.app 查看日志输出 |
|||
- 数据库文件存储在应用的 Documents/Databases 目录下 |
|||
|
|||
## 开发者须知 |
|||
|
|||
如果需要扩展此插件的功能，比如添加新的表或字段，应同时更新 Android 和 iOS 端的实现，并确保在版本升级时提供适当的数据库迁移策略。 |
|||
|
|||
数据库迁移逻辑目前实现为重建表，在生产环境中应该改为保留用户数据的方式。 |

# iOS蓝牙配置说明 |
|||
|
|||
## 所需权限 |
|||
|
|||
要在iOS中使用经典蓝牙功能，需要在应用的`Info.plist`中添加以下配置： |
|||
|
|||
### 1. 外部附件协议支持 |
|||
|
|||
在Info.plist中添加`UISupportedExternalAccessoryProtocols`数组，并添加你的设备支持的协议。如果不确定，可以先添加常见的协议： |
|||
|
|||
```xml |
|||
<key>UISupportedExternalAccessoryProtocols</key> |
|||
<array> |
|||
<string>com.example.protocol</string> |
|||
<!-- 添加其他你设备支持的协议 --> |
|||
</array> |
|||
``` |
|||
|
|||
### 2. 蓝牙使用说明 |
|||
|
|||
在iOS 13及以上版本中，需要添加蓝牙使用说明： |
|||
|
|||
```xml |
|||
<key>NSBluetoothAlwaysUsageDescription</key> |
|||
<string>我们需要使用蓝牙来连接您的音频设备</string> |
|||
``` |
|||
|
|||
对于iOS 13以下版本： |
|||
|
|||
```xml |
|||
<key>NSBluetoothPeripheralUsageDescription</key> |
|||
<string>我们需要使用蓝牙来连接您的音频设备</string> |
|||
``` |
|||
|
|||
## 常见问题 |
|||
|
|||
1. 如果看不到任何设备，请确保： |
|||
- 设备已配对并连接到iOS设备 |
|||
- 设备是MFi认证的（Made for iPhone/iPad），因为iOS对经典蓝牙有限制 |
|||
- 添加了正确的协议字符串 |
|||
|
|||
2. 蓝牙状态变化不及时： |
|||
- iOS系统对蓝牙状态变化的通知可能有延迟 |
|||
- 请确保用户已经授权蓝牙权限 |

# DeepVoice Utils iOS 实现 |
|||
|
|||
## 简介 |
|||
|
|||
本模块是 `deepvoice_utils` 插件的 iOS 实现部分，主要提供以下功能： |
|||
|
|||
- 文件日志记录（FileLogger）：将日志记录到文件，方便调试和问题排查 |
|||
|
|||
## 使用说明 |
|||
|
|||
### 日志系统 |
|||
|
|||
该插件自动初始化日志系统，开发者无需手动调用初始化方法。日志文件默认保存在应用的 Documents 目录下的 logs 文件夹中，按日期分文件存储。 |
|||
|
|||
## 配置要求 |
|||
|
|||
- iOS 11.0 或更高版本 |
|||
- Swift 5.0 |
|||
- 确保应用拥有文件写入权限 |
|||
|
|||
## 开发说明 |
|||
|
|||
### 文件结构 |
|||
|
|||
- `DeepvoiceUtilsPlugin.swift`：插件主类，负责与 Flutter 交互 |
|||
- `FileLogger.swift`：日志系统实现，提供日志记录功能 |
|||
- `SwiftDeepvoiceUtilsPlugin.swift`：命名约定桥接类 |
|||
- `DeepvoiceUtilsPlugin.h/.m`：Objective-C 桥接文件 |
|||
|
|||
### 自定义日志目录 |
|||
|
|||
如需使用自定义日志目录，可以在应用启动时手动调用初始化方法： |
|||
|
|||
```swift |
|||
import deepvoice_utils |
|||
|
|||
// 在 AppDelegate 中 |
|||
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { |
|||
// 自定义日志目录 |
|||
let customDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("custom_logs") |
|||
FileLogger.initialize(withDirectory: customDirectory) |
|||
|
|||
return true |
|||
} |
|||
``` |
|||
|
|||
### 清理旧日志 |
|||
|
|||
默认情况下，日志系统不会自动清理旧日志。如果需要清理，可以手动调用： |
|||
|
|||
```swift |
|||
// 清理7天前的日志 |
|||
FileLogger.cleanOldLogs(daysToKeep: 7) |
|||
``` |

a specialized package that includes platform-specific implementation code for |
|||
Android and/or iOS. |
|||
|
|||
For help getting started with Flutter development, view the |

# using method channels. |

# The Android 'package' specifies package in which the registered class is. |

# This is required for using method channels on Android. |

# The 'ffiPlugin' specifies that native code should be built and bundled. |

# This is required for using `dart:ffi`. |
