iOS - WatchKit如何将消息/数据从iPhone应用程序发送到WatchKit应用程序? [英] iOS - WatchKit how to send message/data from iPhone app to WatchKit app?
问题描述
我正在创建一个WatchKit应用程序,并想知道如何从iPhone向Watch发送消息/数据?
I am creating a WatchKit app and was wondering how to send a message/data from the iPhone to the Watch?
我知道如何以其他方式做到这一点周围(手表 - >手机)使用' openParentApplication:回复:'和'应用程序:handleWatchKitExtensionRequest:回复:'但无法找到有关如何通过手机进行通信的任何文档观看。
I know how to do it the other way around (watch -> phone) using 'openParentApplication:reply:' and 'application:handleWatchKitExtensionRequest:reply:' but can't find any documentation on how to communicate from phone to watch.
简单的设置是iPhone应用程序有一个按钮,按下时应该更新Watch应用程序上的标签。
Simple setup would be the iPhone app has a button that when pressed should update a label on the Watch app.
有人能指出我正确的方向吗?
Can anyone point me in the right direction?
推荐答案
首先,您必须为目标启用应用程序组:
First, you have to enable app groups for your target:
然后你可以开始通过 NSUserDefaults
写入和读取对象:
Then you can start to write and read objects via NSUserDefaults
:
// write
let sharedDefaults = NSUserDefaults(suiteName: appGroupName)
sharedDefaults?.setInteger(1, forKey: "myIntKey")
// read
let sharedDefaults = NSUserDefaults(suiteName: appGroupName)
let myIntValue = sharedDefaults?.integerForKey("myIntKey")
