如何在SWIFT中将数据从Iphone发送到OS2中的Watchkit

从那篇文章：首先,您将创建并激活WCSession,如下所示：

if (WCSession.isSupported()) {
    let session = WCSession.defaultSession()
    session.delegate = self
    session.activateSession()
}

转移字典：

let applicationDict = // Create a dict of application data
let transfer = WCSession.defaultSession().transferUserInfo(applicationDict)

然后,在接收端,您将需要实现session：didReceiveUserInfo：(Developer documentation).请注意,根据Apple的“watchOS2 Transition Guide”

To begin communication,both your Watch app and your iOS app must have an active WCSession object. Typically,each app creates,configures,and activates a session object at launch time and stores a reference to it in a central location. When you want to send data,you retrieve the session object and call its methods.
