推荐答案

所以在 WatchOS 2 上是可能的！

So on WatchOS 2 that is possible !

你必须在 iPhone 端做:

You have to do on iPhone side :

第一:

import WatchConnectivity

然后:

   if WCSession.isSupported() { // check if the device support to handle an Apple Watch
        let session = WCSession.defaultSession()
        session.delegate = self
        session.activateSession() // activate the session

        if session.paired { // Check if the iPhone is paired with the Apple Watch
                // Do stuff
        }
    }
