推荐答案

从 watchOS2 开始，除了 WatchConnectivity 框架之外，你没有任何用于在 iOS 和 watchOS 应用程序之间进行通信的内置函数.

Since watchOS2, you don't have any built in function for communicating between the iOS and watchOS app than the WatchConnectivity framework.

根据您问题中提供的信息，updateApplicationContext(_:) 函数似乎是您问题的最佳解决方案.您可以使用此功能发送数据字典，系统会尝试确保在您的应用程序向用户显示时已收到数据.如果在应用对用户可见(在前台运行)之前多次调用该函数，系统会覆盖之前的数据，因此 Watch 应用只会接收要显示的最新数据.

From the information provided in your question, the updateApplicationContext(_:) function seems to be the best solution for your problem. You can send a dictionary of data with this function and the system tries to make sure that the data is received by the time your app is displayed to the user. If the function is called several times before the app would be visible to the user (run in the foreground), the system overwrites the previous data, so the Watch app only receives the most recent data to display.
