当我将设备与Xcode断开连接时，推送通知不起作用 [英] Push Notifications Are Not working When I disconnect my device from Xcode

问题描述

我正在使用快速语言开发IOS应用程序.我已将基于Firebase的推送通知添加到我的项目中.当我的设备连接到xcode或在我的设备上调试我的应用程序时，它们可以正常工作.但是，无论何时我断开设备与xcode的连接或使用未调试推送通知的应用程序都无法正常工作.我正在寻找解决方案

I am Developing an IOS App using swift language. I have added Firebase based push notifications to my project. they works correctly when my device is attached to xcode or when i debug my app on my device. But when ever i disconnect my device from xcode or i use app without debugging push notification doesn't work. I am looking for a solution

我在应用程序委托文件中的代码

My code in App Delegate File

在didFinishLaunchingWithOptions函数中

In didFinishLaunchingWithOptions function

if #available(iOS 10.0, *) {
        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.current().delegate = self

        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(options: authOptions,
                                                                completionHandler: { (bool, err) in

        })

    } else {

        let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)

    }

    application.registerForRemoteNotifications()
    UIApplication.shared.applicationIconBadgeNumber = 0

在didregisterdevicewithtoken函数中

in didregisterdevicewithtoken function

 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    print("APNs token retrieved: \(deviceToken)")

    // With swizzling disabled you must set the APNs token here.
    if let refreshedToken = InstanceID.instanceID().token() {
        print("InstanceID token: \(refreshedToken)")

    }
    let tokenT = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    print(tokenT)
    guard let token = InstanceID.instanceID().token() else {return}
    AppDelegate.DEVICEID = token
    print(token)
    UserDefaults.standard.set(token, forKey: "token")

    connectToFCM()


}

并生成通知

 func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)

    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    if let msg = userInfo["desc"] as? String
    {
        let title = userInfo["noti_title"] as? String
        createNotification(message: msg, title: title ?? "" )

    }

    // Print full message.
    print(userInfo)

    completionHandler(UIBackgroundFetchResult.newData)
}


func createNotification(message: String, title: String) {

    let content = UNMutableNotificationContent()
    content.title =  title
    content.body = message


    let triger = UNTimeIntervalNotificationTrigger(timeInterval: 2, repeats: false )
    let request = UNNotificationRequest(identifier: "TextMessage", content: content, trigger: triger)



    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}

UNUserNotificationCenterDelegate

UNUserNotificationCenterDelegate

extension AppDelegate : UNUserNotificationCenterDelegate {

// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification,                            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    let userInfo = notification.request.content.userInfo

    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    print(userInfo)

    // Change this to your preferred presentation option
    completionHandler([.alert,.badge,.sound])
}


func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    let application = UIApplication.shared

    if(application.applicationState == .active){
        print("user tapped the notification bar when the app is in foreground")

        window = UIWindow(frame: UIScreen.main.bounds)
        window?.makeKeyAndVisible()

        //        let layout = UICollectionViewFlowLayout()
        window?.rootViewController = UINavigationController(rootViewController: NotificationViewController())


    }

    if(application.applicationState == .inactive)
    {
        print("user tapped the notification bar when the app is in background")
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.makeKeyAndVisible()

        //        let layout = UICollectionViewFlowLayout()
        window?.rootViewController = UINavigationController(rootViewController: NotificationViewController())

    }

    /* Change root view controller to a specific viewcontroller */
    // let storyboard = UIStoryboard(name: "Main", bundle: nil)
    // let vc = storyboard.instantiateViewController(withIdentifier: "ViewControllerStoryboardID") as? ViewController
    // self.window?.rootViewController = vc

    completionHandler()
}

func connectToFCM()
{
    Messaging.messaging().shouldEstablishDirectChannel = true
}
func initializeNotificationServices() -> Void {
    let settings = UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil)
    UIApplication.shared.registerUserNotificationSettings(settings)

    // This is an asynchronous method to retrieve a Device Token
    // Callbacks are in AppDelegate.swift
    // Success = didRegisterForRemoteNotificationsWithDeviceToken
    // Fail = didFailToRegisterForRemoteNotificationsWithError
    UIApplication.shared.registerForRemoteNotifications()

推荐答案

我已经解决了这个问题.现在，我在Firebase控制台中添加了生产Apn证书，并从Firebase控制台中删除了开发Apn证书.对于那些有同样问题的人，请从apple.developers生成您的生产apn，然后在build选项卡中将项目方案从debug更改为release.

I have solved this problem. Now i have added production Apn certificate in firebase console and removed development apn certificate from firebase console. for those who had same issue please generate ur production apn from apple.developers and change your project scheme from debug to release in build tab.
