Firebase消息传递。iOS应用在后台模式或关闭时不接收通知

Question

在后台或关机模式下，我无法让我的应用程序接收通知。我遵循了Firebase指南，了解了如何在我的应用程序中实现Firebase消息传递。以前我使用过GCM（谷歌云消息），它运行得很好，但自从升级到Firebase后，我无法让它工作。一旦启动我的应用程序，我在后台或关机时发送的所有通知（通过firebase控制台通知）都会被发送。

我有：

• 已在Firebase控制台上创建项目

值得一提的是，我已经通过在我的Info.plist文件中将FirebasApp委托ProxyEnable设置为NO来禁用swizzling。

相关代码：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
  let types: UIUserNotificationType = [UIUserNotificationType.Badge, UIUserNotificationType.Alert, UIUserNotificationType.Sound]
    let settings: UIUserNotificationSettings = UIUserNotificationSettings( forTypes: types, categories: nil )
    application.registerUserNotificationSettings( settings )
    application.registerForRemoteNotifications()

    FIRApp.configure()
}

func connectToFcm() {
    FIRMessaging.messaging().connectWithCompletion { (error) in
        if (error != nil) {
            print("Unable to connect with FCM")
        } else {
            print("Connected to FCM.")
            self.refreshToken()
        }
    }
}

func refreshToken(){
    if let refreshedToken = FIRInstanceID.instanceID().token() {

        gcmToken = refreshedToken

        userDefaults.setValue(gcmToken, forKey: CONSTANTS.GCM_TOKEN)

        if(userDefaults.boolForKey("UserLoggedIn")){
            pushGcmToken() //push the token to server
        }
    }
}

func onTokenRefresh() {
    refreshToken()
    // Connect to FCM since connection may have failed when attempted before having a token.
    connectToFcm()
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    NSLog("didReceiveRemoteNotification \(userInfo)")

    FIRMessaging.messaging().appDidReceiveMessage(userInfo)

    handleRemoteNotification(userInfo)

}

func handleRemoteNotification(userInfo: [NSObject : AnyObject]){
    if let notification = userInfo["notification"] as? [NSObject : AnyObject]{

        let bodyNot = notification["body"] as! String
        var titleNot = "Ändring"
        var category = "UNIFIED_OTHER_CATEGORY"
        if(notification["title"] != nil){
            titleNot = (notification["title"] as! String == "Call" ? "Inkomande samtal" : notification["title"]) as! String
            category = "UNIFIED_CALL_CATEGORY"
        }

        let notis = UILocalNotification()
        notis.alertTitle = titleNot

        notis.alertBody = bodyNot
        notis.soundName = UILocalNotificationDefaultSoundName // play default sound
        notis.userInfo = ["UUID": "122" ] // assign a unique identifier to the notification so that we can retrieve it later
        notis.category = category
        notis.fireDate = NSDate()
        UIApplication.sharedApplication().scheduleLocalNotification(notis)
    }
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    NSLog("didRegisterForRemoteNotificationsWithDeviceToken \(deviceToken)")
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
}

我甚至尝试过调酒。同样的事情发生了。我将非常感谢任何帮助或提示到正确的方向。

我配置下面的东西和它的工作罚款为我的应用程序，

info.plist两把钥匙

<key>FIRMessagingAutoRegisterEnabledflag</key>
    <true/>
<key>FirebaseAppDelegateProxyEnabled</key>
    <false/>

测试通知开发模式的代码

[[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];

从Firebase控制台下载GoogleService-Info.plist并将其放在应用程序中
