state AppleAccountStatus {
[*] --> AppleAccountForbidden
AppleAccountForbidden --> AppleAccountNormal
AppleAccountNormal --> AppleAccountWrongPassword
AppleAccountNormal --> AppleAccountLimited
AppleAccountNormal --> AppleAccountTmpStoppedByTooManyRequest
AppleAccountTmpStoppedByTooManyRequest --> AppleAccountNormal
}
state AppleRechargeOrderStatus {
[*] --> AppleRechargeOrderWaiting
AppleRechargeOrderWaiting --> AppleRechargeOrderProcessing
AppleRechargeOrderProcessing --> AppleRechargeOrderSuccess
AppleRechargeOrderProcessing --> AppleRechargeOrderFail
AppleRechargeOrderProcessing --> AppleRechargeOrderLimited
AppleRechargeOrderProcessing --> AppleRechargeOrderExpired
}
state AppleOrderItunesStatus {
[*] --> AppleRechargeItunesStatusSuccess
AppleRechargeItunesStatusSuccess --> AppleRechargeItunesRefund
AppleRechargeItunesStatusFail --> AppleRechargeItunesStatusFailWithWrongCode
AppleRechargeItunesStatusFail --> AppleRechargeItunesStatusFailWithRepeatCharge
AppleRechargeItunesStatusFail --> AppleRechargeItunesStatusWrongPassword
}
```

GetConfig --> CheckSteal["检查偷卡模式"]
CheckSteal --> |开启| SetStealRule["设置偷卡规则"]
CheckSteal --> |关闭| ReturnNormal["返回正常模式"]
SetStealRule --> SaveConfig["保存配置"]
SaveConfig --> UpdateCache["更新缓存"]
UpdateCache --> End([结束])
ReturnNormal --> End
```

## 性能考虑
Apple集成系统在设计时考虑了多种性能优化策略：

1. **缓存机制**：使用内存缓存存储频繁访问的数据，减少数据库查询
2. **定时任务**：使用gtimer和gcron处理异步任务，避免阻塞主线程
3. **事务管理**：合理使用数据库事务，确保数据一致性的同时优化性能
4. **并发控制**：使用gmutex进行并发控制，防止资源竞争
5. **连接池**：使用数据库连接池提高数据库访问效率

系统还实现了超时检测机制，对于长时间未处理的订单会自动重置状态，确保系统的健壮性。

## 故障排除指南
### 常见问题及解决方案

| 问题现象 | 可能原因 | 解决方案 |
|---------|--------|--------|
| 订单长时间处于"等待充值"状态 | 超时检测未触发 | 检查定时任务是否正常运行 |
| 账户无法分配 | 账户状态异常 | 检查账户状态是否为正常可用 |
| 充值金额不一致 | 金额验证失败 | 使用手动修正金额功能 |
| 回调失败 | 网络问题或URL错误 | 检查回调URL配置和网络连接 |
| 偷卡功能未生效 | 配置未开启 | 检查偷卡模式是否已启用 |

### 调试工具
系统提供了多种调试工具：
- 手动回调订单功能
- 手动修正金额功能
- 订单状态重置功能
- 账户状态查询功能
