我正在尝试使用通过 WatchConnectivity 从 IOS / iPhone 传输的数据来更新 watchOS2 时钟套件复杂功能。
尽管进行了相当多的研究，但到目前为止还没有成功。我发现虽然其他帖子描述了类似的挑战（还没有解决方案）
我面临3个问题：
1）来自 ComplicationController 的 sendMessage 似乎没有唤醒 IOS 父应用程序（而从 InterfaceController 发送的相同 sendMessage 确实唤醒了 IOS 父应用程序）
2）即使将值传输到 ComplicationController（通过 sendUserInfoToComplication 并且当 IOS 应用程序处于前台时），显示在复杂功能中的值有时也会更新（尚未找到为什么有时会/有时不会的模式）
3）我将“getNextRequestUpdate..”设置为 2 分钟（用于测试目的）。不过，这似乎没有任何区别。（即使在模拟器中也可以在任意时间触发，但没有使用“预算”/我设置了停止器来验证）
请注意，我对 IOS / Swift 编程比较陌生。但我看到，基于其他问题/帖子，我似乎并不是唯一一个为此苦苦挣扎的人。
这里是示例代码：

此外，在运行模拟器时，我会收到大量与以下类似的消息：
