iPhone 和 Apple Watch 之间的 WatchConnectivity 超时错误

Question

我正在尝试使用 WatchConnectivity 框架将字符串从 Apple Watch 发送到 iPhone。

\n\n

我启动了两个会话，一个是 WCSession，一个是 HKSession，因为我想在读取心率信息时将其从手表传输到 iPhone。（如果有更好的方法请告诉我）。

如果有帮助，我已经发布了我收到的日志消息。

WCErrorCodeTransferTimedOut->IDSErrorTypeTimedOut->IDSResponseTimedOut

我通过重新启动 iPhone 和手表解决了这个错误。
