如何在SWIFT的OS2中将数据从Iphone发送到Watchkit [英] How to send data from Iphone to Watchkit in OS2 in SWIFT

问题描述

我想将iPhone的字典发送到watchOS 2中的Watchkit.

I want to send a dictionary from iPhone to Watchkit in watchOS 2.

在watchOS 1中，它对我来说适合应用组，但在watchOS 2中，我知道我们必须使用WCSession，但我不知道如何使用它.

In watchOS 1 it works fine for me with appgroups but in watchOS 2 I know that we have to use WCSession but I don't know how to use it.

请帮助我找到解决方法.

Please help me find the solution.

推荐答案

此在那篇文章中:首先，您将像这样创建并激活WCSession:

From that post: First, you'll create and activate a WCSession like so:

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

用于传输字典:

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

然后，在接收端，您需要实现session:didReceiveUserInfo:(

Then, on the receiving end, you'll need to implement session:didReceiveUserInfo: (Developer documentation). Note, according to Apple's "watchOS2 Transition Guide,"

要开始通信，Watch应用程序和iOS应用程序都必须具有活动的WCSession对象.通常，每个应用在启动时都会创建，配置和激活会话对象，并将对它的引用存储在中央位置.当您要发送数据时，可以检索会话对象并调用其方法.

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.
