问题描述

我正在做一个示例项目，我喜欢将数据从 iphone 发送到 WatchKit.我不知道如何做到这一点.任何帮助将不胜感激.提前致谢

I am doing a sample project in which i like to send data from iphone to WatchKit. I have no idea of how to do this. Any help will be appreciated. Thanks in advance

推荐答案

在 AppDelegate 中添加这个方法:

Add this method in the AppDelegate:

func application(application: UIApplication!,
handleWatchKitExtensionRequest userInfo: [NSObject : AnyObject]!,
   reply: (([NSObject : AnyObject]!) -> Void)!)
{
   //define your dictionary
   reply(yourDict)
}

在 Apple Watch 扩展中的任意位置添加:

Add this anywhere in the Apple Watch Extension:

var dict = ["test" : 4] //your dictionary/request to sent to the iPhone
if !WKInterfaceController.openParentApplication(dict, reply: { (reply,error) -> Void in
    println("\(reply)") //your reply data as Dictionary
}) {
    println("ERROR")
}

第一个函数将使用 WKInterfaceController.openParentApplication 触发，并回复 reply 参数中的字典.

The first function will trigger with WKInterfaceController.openParentApplication and will reply the dictionary in the reply parameter.
