+```
+
+## 使用示例
+
+### 1. 注册设备令牌
+```typescript
+// iOS客户端获取设备令牌后，调用此API
+POST /api/push-notifications/register-token
+{
+  "deviceToken": "a9d0ed10e9cfd022a61cb08753f49c5a0b0dfb383697bf9f9d750a1003da19c7",
+  "deviceType": "IOS",
+  "appVersion": "1.0.0",
+  "osVersion": "iOS 15.0",
+  "deviceName": "iPhone 13"
+}
+```
+
+### 2. 发送推送通知
+```typescript
+// 在业务服务中调用推送服务
+await this.pushNotificationsService.sendNotification({
+  userIds: ['user_123'],
+  title: '训练提醒',
+  body: '您今天的普拉提训练还未完成，快来打卡吧！',
+  payload: {
+    type: 'training_reminder',
+    trainingId: 'training_123'
+  }
+});
+```
+
+### 3. 使用模板发送推送
+```typescript
+// 使用预定义模板发送推送
+await this.pushNotificationsService.sendNotificationByTemplate(
+  'user_123',
+  'training_reminder',
+  {
+    userName: '张三',
+    trainingName: '核心力量训练'
+  }

+```
+
+#### 创建推送模板
+
+```bash
+POST /api/push-notifications/templates
+Authorization: Bearer <access_token>
+Content-Type: application/json
+
+{
+  "templateKey": "custom_reminder",
+  "title": "自定义提醒",

+    "reminderId": "{{reminderId}}"
+  },
+  "pushType": "ALERT",
+  "priority": 8
+}
+```
+

+
+```bash
+PUT /api/push-notifications/templates/:id
+Authorization: Bearer <access_token>
+Content-Type: application/json
+
+{
+  "title": "更新后的标题",

+
+## 代码示例
+
+### 1. 在业务服务中使用推送功能
+
+```typescript
+import { Injectable } from '@nestjs/common';
+import { PushNotificationsService } from '../push-notifications/push-notifications.service';
+
+@Injectable()
+export class TrainingService {
+  constructor(
+    private readonly pushNotificationsService: PushNotificationsService,
+  ) {}
+
+  async sendTrainingReminder(userId: string, trainingName: string): Promise<void> {
+    // 使用模板发送推送
+    await this.pushNotificationsService.sendNotificationByTemplate({
+      userIds: [userId],
+      templateKey: 'training_reminder',
+      data: {
+        userName: '用户', // 可以从用户服务获取
+        trainingName,
+      },
+      payload: {
+        type: 'training_reminder',
+        trainingId: 'training_123',
+      },
+    });
+  }
+
+  async sendWorkoutCompletionNotification(userId: string, workoutName: string, calories: number): Promise<void> {
+    // 直接发送推送
+    await this.pushNotificationsService.sendNotification({
+      userIds: [userId],
+      title: '训练完成',
+      body: `太棒了！您已完成${workoutName}训练，消耗了${calories}卡路里。`,
+      payload: {
+        type: 'workout_completed',
+        workoutId: 'workout_123',
+        calories,
+      },
+      sound: 'celebration.caf',
+      badge: 1,
+    });
+  }
+}
+```
+
+### 2. 在控制器中处理设备令牌注册
+
+```typescript
+import { Controller, Post, Body, UseGuards } from '@nestjs/common';
+import { ApiTags, ApiOperation } from '@nestjs/swagger';
+import { PushNotificationsService } from '../push-notifications/push-notifications.service';
+import { RegisterDeviceTokenDto } from '../push-notifications/dto/register-device-token.dto';
+import { CurrentUser } from '../common/decorators/current-user.decorator';
+import { AccessTokenPayload } from '../users/services/apple-auth.service';
+import { JwtAuthGuard } from '../common/guards/jwt-auth.guard';
+
+@ApiTags('用户设备')
+@Controller('user/device')
+@UseGuards(JwtAuthGuard)
+export class UserDeviceController {
+  constructor(
+    private readonly pushNotificationsService: PushNotificationsService,
+  ) {}
+
+  @Post('register-token')
+  @ApiOperation({ summary: '注册设备推送令牌' })
+  async registerDeviceToken(
+    @CurrentUser() user: AccessTokenPayload,
+    @Body() registerTokenDto: RegisterDeviceTokenDto,
+  ) {
+    return this.pushNotificationsService.registerToken(user.sub, registerTokenDto);
+  }
+}
+```
+
+## 预定义推送模板
+
+系统已预置以下推送模板：
+
+### 1. 训练提醒 (training_reminder)
+- **用途**: 提醒用户完成训练
+- **变量**: `{{userName}}`, `{{trainingName}}`
+- **示例**: "您好张三，您今天的核心力量训练还未完成，快来打卡吧！"
+
+### 2. 饮食记录提醒 (diet_record_reminder)
+- **用途**: 提醒用户记录饮食
+- **变量**: `{{userName}}`
+- **示例**: "您好张三，您还没有记录今天的饮食，记得及时记录哦！"
+
+### 3. 挑战进度 (challenge_progress)
+- **用途**: 通知用户挑战进度
+- **变量**: `{{challengeName}}`, `{{progress}}`
+- **示例**: "恭喜您！您已完成30天挑战的50%，继续加油！"
+
+### 4. 会员到期提醒 (membership_expiring)
+- **用途**: 提醒用户会员即将到期
+- **变量**: `{{userName}}`, `{{days}}`
+- **示例**: "您好张三，您的会员将在7天后到期，请及时续费以免影响使用。"
+
+### 5. 会员已到期 (membership_expired)
+- **用途**: 通知用户会员已到期
+- **变量**: `{{userName}}`
+- **示例**: "您好张三，您的会员已到期，请续费以继续享受会员服务。"
+
+### 6. 成就解锁 (achievement_unlocked)
+- **用途**: 庆祝用户解锁成就
+- **变量**: `{{achievementName}}`
+- **示例**: "恭喜您解锁了"连续训练7天"成就！"
+
+### 7. 训练完成 (workout_completed)
+- **用途**: 确认用户完成训练
+- **变量**: `{{workoutName}}`, `{{calories}}`
+- **示例**: "太棒了！您已完成核心力量训练，消耗了150卡路里。"
+
+## 错误处理
+
+### 常见错误码
+
+| 错误码 | 描述 | 解决方案 |
+|--------|------|----------|
+| 400 | 请求参数错误 | 检查请求参数格式和必填字段 |
+| 401 | 未授权访问 | 确保提供了有效的访问令牌 |
+| 404 | 资源不存在 | 检查用户ID或模板键是否正确 |
+| 429 | 请求频率过高 | 降低请求频率，实现退避重试 |
+| 500 | 服务器内部错误 | 检查服务器日志，联系技术支持 |
+
+### APNs错误处理
+
+系统会自动处理以下APNs错误：
+
+- **Unregistered**: 自动停用无效的设备令牌
+- **BadDeviceToken**: 记录错误并停用令牌
+- **DeviceTokenNotForTopic**: 记录错误日志
+- **TooManyRequests**: 实现退避重试机制
+- **InternalServerError**: 自动重试
+
+## 监控和日志
+
+### 1. 推送状态监控
+
+可以通过以下方式监控推送状态：
+
+```typescript
+// 获取推送统计
+const stats = await this.pushMessageService.getMessageStats();
+console.log(`推送成功率: ${stats.successRate}%`);
+console.log(`错误分布:`, stats.errorBreakdown);
+```
+
+### 2. 日志查看
+
+推送相关日志包含以下信息：
+- 推送请求和响应
+- APNs连接状态
+- 错误详情和堆栈跟踪
+- 性能指标
+
+## 最佳实践
+
+### 1. 推送时机
+- 避免在深夜或凌晨发送推送
+- 根据用户时区调整推送时间
+- 尊重用户的推送偏好设置
+
+### 2. 推送内容
+- 保持推送内容简洁明了
+- 使用个性化内容提高用户参与度
+- 避免发送过于频繁的推送
+
+### 3. 性能优化
+- 使用批量推送减少网络请求
+- 实现推送优先级管理
+- 定期清理无效的设备令牌
+
+### 4. 安全考虑
+- 保护用户隐私数据
+- 实现推送内容审核机制
+- 使用HTTPS进行API通信
+
+## 故障排除
+
+### 1. 推送不生效
+- 检查APNs配置是否正确
+- 验证设备令牌是否有效
+- 确认Bundle ID是否匹配
+
+### 2. 推送延迟
+- 检查网络连接状态
+- 验证APNs服务器状态
+- 调整推送优先级设置
+
+### 3. 设备令牌失效
+- 实现令牌自动更新机制
+- 定期清理无效令牌
+- 监控令牌失效率
+
+## 扩展功能
+
+### 1. 推送统计分析
+- 实现推送打开率统计
+- 分析用户行为数据
+- 优化推送策略
+
+### 2. A/B测试
+- 实现推送内容A/B测试
+- 比较不同推送策略效果
+- 优化推送转化率
+
+### 3. 多平台支持
+- 扩展Android推送功能
+- 统一推送接口设计
+- 实现平台特定功能
+
+## 总结
+
+iOS推送功能已完全集成到系统中，提供了完整的推送令牌管理、消息发送和模板系统。通过遵循本指南，您可以轻松地在应用中实现各种推送场景，提升用户体验和参与度。

+
+## 5. 接口使用示例
+
+### 5.1 注册设备令牌
+```bash
+POST /api/push-notifications/register-token
+Authorization: Bearer <access_token>
+Content-Type: application/json
+
+{
+  "deviceToken": "a9d0ed10e9cfd022a61cb08753f49c5a0b0dfb383697bf9f9d750a1003da19c7",
+  "deviceType": "IOS",
+  "appVersion": "1.0.0",
+  "osVersion": "iOS 15.0",
+  "deviceName": "iPhone 13"
+}
+```
+
+### 5.2 发送推送通知
+```bash
+POST /api/push-notifications/send
+Content-Type: application/json
+
+{
+  "userIds": ["user_123", "user_456"],
+  "title": "训练提醒",
+  "body": "您今天的普拉提训练还未完成，快来打卡吧！",
+  "payload": {
+    "type": "training_reminder",
+    "trainingId": "training_123"
+  },
+  "pushType": "ALERT",
+  "priority": 10
+}
+```
+
+### 5.3 使用模板发送推送
+```bash
+POST /api/push-notifications/send-by-template
+Content-Type: application/json
+
+{
+  "userIds": ["user_123"],
+  "templateKey": "training_reminder",
+  "data": {
+    "userName": "张三",
+    "trainingName": "核心力量训练"
+  },
+  "payload": {
+    "type": "training_reminder",
+    "trainingId": "training_123"
+  }
+}
+```
+
+## 6. 错误处理
+
+### 6.1 错误类型定义
+```typescript
+export enum PushErrorCode {
+  INVALID_DEVICE_TOKEN = 'INVALID_DEVICE_TOKEN',
+  DEVICE_TOKEN_NOT_FOR_TOPIC = 'DEVICE_TOKEN_NOT_FOR_TOPIC',
+  TOO_MANY_REQUESTS = 'TOO_MANY_REQUESTS',
+  INTERNAL_SERVER_ERROR = 'INTERNAL_SERVER_ERROR',
+  TEMPLATE_NOT_FOUND = 'TEMPLATE_NOT_FOUND',
+  USER_NOT_FOUND = 'USER_NOT_FOUND',
+  INVALID_PAYLOAD = 'INVALID_PAYLOAD',
+}
+
+export class PushException extends HttpException {
+  constructor(
+    errorCode: PushErrorCode,
+    message: string,
+    statusCode: HttpStatus = HttpStatus.BAD_REQUEST,
+  ) {
+    super({ code: errorCode, message }, statusCode);
+  }
+}
+```
+
+### 6.2 全局异常处理
+```typescript
+@Catch(PushException, Error)
+export class PushExceptionFilter implements ExceptionFilter {
+  catch(exception: unknown, host: ArgumentsHost) {
+    const ctx = host.switchToHttp();
+    const response = ctx.getResponse<Response>();
+    
+    if (exception instanceof PushException) {
+      response.status(exception.getStatus()).json(exception.getResponse());
+    } else {
+      response.status(HttpStatus.INTERNAL_SERVER_ERROR).json({
+        code: 'INTERNAL_SERVER_ERROR',
+        message: '推送服务内部错误',
+      });
+    }
+  }
+}
+```
+
+## 7. 性能优化策略
+
+### 7.1 连接池管理
+- 使用HTTP/2连接池提高并发性能
+- 实现连接复用和心跳保活
+- 动态调整连接池大小
+
+### 7.2 批量处理优化
+- 实现批量推送减少网络请求
+- 使用队列系统处理大量推送请求
+- 实现推送优先级和限流机制
+
+### 7.3 缓存策略
+- 缓存用户设备令牌减少数据库查询
+- 缓存推送模板提高渲染性能
+- 实现分布式缓存支持集群部署
