iPhone未从AppleWatch接收ApplicationContext

我已经创建了一个程序来测试从iPhone和AppleWatch来回发送数据,反之亦然。我已经设置好了,所以AppleWatch上有一个按钮,iPhone上有一个按钮。当按下iPhone One时,它将发送数据,并将AppleWatch上的按钮重命名为该数据字符串的名称。

然后,我对iPhone的AppleWatch实现了相同的代码,但出于某种原因,iPhone似乎没有接收到数据。以下是iPhone的代码:

//  ViewController.swift

import UIKit
import Foundation
import WatchConnectivity

class WatchManager: UIViewController, WCSessionDelegate {

    var watchSession: WCSession? {
        didSet {
            if let session = watchSession {
                session.delegate = self
                session.activate()
            }
        }
    }

    override func viewDidLoad(){
        super.viewDidLoad()

        watchSession = WCSession.default

    }

    private func sendDict(_ dict: [String: Any]) {
        do {
            try self.watchSession?.updateApplicationContext(dict)
        } catch {
            print("Error sending dictionary \(dict) to Apple Watch!")
        }
    }

    @IBOutlet weak var transferButton: UIButton!

    @IBAction func dataTransfer(_ sender: Any) {
        sendDict(["DataKey": UUID().uuidString])
        print("sent")
    }

    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        print("Session activation did complete")
    }

    public func sessionDidBecomeInactive(_ session: WCSession) {
        print("session did become inactive")
    }

    public func sessionDidDeactivate(_ session: WCSession) {
        print("session did deactivate")
    }

    func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) {
        print("phone received app context: ", applicationContext)
        if let temperature = applicationContext["DataKey"] as? String {
            self.transferButton.setTitle(temperature, for: .normal)
        }

    }

}

AppleWatch:

//  InterfaceController.swift

import WatchKit
import Foundation
import WatchConnectivity


class InterfaceController: WKInterfaceController {

    var watchSession: WCSession? {
        didSet {
            if let session = watchSession {
                session.delegate = self
                session.activate()
            }
        }
    }


    @IBOutlet weak var temperatureLabel: WKInterfaceButton!

    private func sendDict(_ dict: [String: Any]) {
        do {
            try self.watchSession?.updateApplicationContext(dict)
        } catch {
            print("Error sending dictionary \(dict) to iPhone!")
        }
    }

    @IBAction func button() {
        let urg = ["DataKey":UUID().uuidString]
        sendDict(urg)
        print("watch sent app context \(urg)")
    }

}

extension InterfaceController: WCSessionDelegate {

    #if os(iOS)
    public func sessionDidBecomeInactive(_ session: WCSession) { }
    public func sessionDidDeactivate(_ session: WCSession) {
        session.activate()
    }
    #endif

    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        print("Session activation did complete")
    }

    func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) {
        print("watch received app context: ", applicationContext)
        if let temperature = applicationContext["DataKey"] as? String {
            self.temperatureLabel.setTitle(temperature)
        }

    }

    override func willActivate() {
        // This method is called when watch view controller is about to be visible to user
        super.willActivate()

        watchSession = WCSession.default

    }

    override func didDeactivate() {
        // This method is called when watch view controller is no longer visible
        super.didDeactivate()
    }

}

我试过更改键的名称(不起作用),我做了它,所以数据值总是在更改(uuid().uuidstring),并保持不变。我尝试的其他方法包括创建一个标签,并尝试重命名它,而不是将失败的按钮重命名,最后,而不是重命名按钮,只是发送一些确认信息,确认它接收到的数据返回到了失败的Apple Watch。

任何帮助都会非常感谢,我希望这不是一个愚蠢的错误。
