如果用户使用不带手表扩展功能的Apple Watch，如何在iOS应用中进行跟踪?

问题描述

我想知道我的用户是否有Apple Watch.如果有很多用户这样做，那么我将为我的iOS应用程序开发Apple Watch应用程序扩展.我可以知道手表是否没有配对吗?

I want to know if my users have Apple Watch. If many user do, so I will develop Apple Watch application extension for my iOS app. Can I know if even watch is not paired?

推荐答案

您应该查看 WatchConnectivity框架.特别是 WCSession 的 isPaired 方法应该可以解决您的问题.

You should look at the WatchConnectivity framework. Especially, the isPaired method of WCSession should solve your problem.

在iPhone应用程序的 application(didFinishLaunchingWithOptions:)方法中，设置并激活WatchConnectivity会话，因为 isPaired 仅返回已激活会话的有效值.

In your iPhone app's application(didFinishLaunchingWithOptions:) method, set up and activate the WatchConnectivity session, since isPaired only returns a valid value for an activated session.

//Set up WatchConnectivity
if WCSession.isSupported() {
   let session = WCSession.default()
   session.delegate = self
   session.activate()
}

在 func session(activationDidCompleteWith)中，您可以检查iPhone是否与Apple Watch配对或不使用此代码行:让userHasAppleWatch = session.isPaired .

In func session(activationDidCompleteWith) you can check if the iPhone is paired with an Apple Watch or not using this line of code:let userHasAppleWatch = session.isPaired.
