ios - iPhone 和 Apple Watch 之间的 WatchConnectivity 超时错误

Question

我正在尝试使用 WatchConnectivity 框架将一个字符串从我的 Apple Watch 发送到我的 iPhone。

我已经开始了两个 session ，一个 WCSession 和一个 HKSession，因为我想在读取时将心率信息从 watch 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。

Answer 1

WCErrorCodeTransferTimedOut->IDSErrorTypeTimedOut->IDSResponseTimedOut我通过重新启动 iphone 和 watch 解决了这个错误。
