错误:"消息回复花了太长时间" - WCSession观看OS2

Question

所以我使用Watch Connectivity来请求从iPhone到Watch的阵列.

这个想法sendMessage来自手表,iPhone将在didReceiveMessage方法中回复数组.

然而,iPhone似乎没有响应,我认为iPhone会在我从Watch发送消息时打开应用程序.我甚至尝试打开应用程序,sendMessage但仍然没有运气.当我等待足够长时间时,我收到以下错误消息:

错误域= WCErrorDomain代码= 7012"消息回复花了太长时间." UserInfo = {NSLocalizedDescription =消息回复耗时太长.,NSLocalizedFailureReason =发生回复超时.}

有人知道我哪里出错吗？

Apple Watch

import WatchKit
import Foundation
import CoreData
import WatchConnectivity

class BookmarkedInterfaceController: WKInterfaceController, WCSessionDelegate {

var session : WCSession!
var objects: [AnyObject]!

@IBOutlet var table: WKInterfaceTable!

override func willActivate() {
    super.willActivate()
    //Check if session is supported and Activate
    if (WCSession.isSupported()) {
        session = WCSession.defaultSession()
        session.delegate = self
        session.activateSession()
    }
    sendMessageToIphone()
}
func sendMessageToIphone() {
    if WCSession.defaultSession().reachable {

        print("WCSession is reachabe")

        let messageDict = ["Request": "iPhone Can You Give Me The Array"]
        WCSession.defaultSession().sendMessage(messageDict, replyHandler: { (replyDict) -> Void in
            print(replyDict)
            }, errorHandler: { (error) -> Void in
                print(error)
        })
    }
}

func session(session: WCSession, didReceiveMessage message: [String : AnyObject]) {
   //recieving message from iphone
    print("recieved message from iphone \(message)")

    objects.append(message["Array"]!)

    print("Objects array = \(objects)")        
}

控制台输出

WCSession是可达阵列nil

iPhone App代表

import UIKit
import CoreData
import WatchConnectivity

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate, WCSessionDelegate {

var window: UIWindow?
var session : WCSession!

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    //Check if session is supported and Activate
    if (WCSession.isSupported()) {
        session = WCSession.defaultSession()
        session.delegate = self
        session.activateSession()
    }
}

func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {

    print("did recieve message from Watch")

    let applicationData = ["Array":["One", "Two", "Three"]]

    replyHandler(applicationData)

}

iPhone的任何内容都没有被执行.即使我手动打开应用程序.

如果您希望手表发送的消息的回复包含请求的数据，您应该将代码更改为以下内容：

手表

func sendMessageToIphone() {
    if WCSession.defaultSession().reachable {

        print("WCSession is reachabe")

        let messageDict = ["Request": "iPhone Can You Give Me The Array"]
        WCSession.defaultSession().sendMessage(messageDict, replyHandler: { (replyDict) -> Void in
            print("Array \(replyDict["array"])")
            }, errorHandler: { (error) -> Void in
                print(error)
        })
    }
}

电话

func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {

    print("did recieve message from Watch")

    let applicationData = ["Array":["One", "Two", "Three"]]

    //If identifier from recievedMessage is for Objects

    replyHandler(applicationData)

}

另外，手表未收到来自手机的 sendMessage 的原因是因为您为正在使用的 sendMessage 调用实现了错误的委托方法。

如果您使用nilreplyHandler调用 sendMessage，则将在接收端调用此委托方法： func session(session: WCSession, didReceiveMessage message: [String : AnyObject])

如果您使用非零的replyHandler调用sendMessage，那么将在接收端调用此委托方法： func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void)
