プッシュ通知がiOS 10に表示されない

Question

iOS 10で通知を受け取るにはどうすればよいですか？以前のバージョンでは、私はfunc application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject])で通知を受け取ることができます。

iOS 10では、AppleがUNNotificationSettingsを紹介しています。私はfunc applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage)でFCMを得ることができます。

しかし、私の電話機にはバックグラウンドで通知が表示されません。

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

    FIRApp.configure() 

    if #available(iOS 10.0, *) { 
     let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound] 
     UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
      authOptions, 
      completionHandler: {_,_ in }) 

     // For iOS 10 display notification (sent via APNS) 
     UNUserNotificationCenter.currentNotificationCenter().delegate = self 
     // For iOS 10 data message (sent via FCM) 
     FIRMessaging.messaging().remoteMessageDelegate = self 

    } else { 
     let settings: UIUserNotificationSettings = 
      UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil) 
     application.registerUserNotificationSettings(settings) 
     application.registerForRemoteNotifications() 
    } 


    return true 
} 

@available(iOS 10, *) 
extension AppDelegate: UNUserNotificationCenterDelegate, FIRMessagingDelegate { 
// Receive displayed notifications for iOS 10 devices. 
func userNotificationCenter(center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) { 
    let userInfo = notification.request.content.userInfo 
    // Print message ID. 
    print("Message ID: \(userInfo["gcm.message_id"]!)") 

    // Print full message. 
    print("%@", userInfo) 

} 


// Receive data message on iOS 10 devices. 
func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage) { 
    print("%@", remoteMessage.appData) 
} 
}

あなたは上記のreturn文には、この方法に

application.registerForRemoteNotifications（）

を移動する必要があります。

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

    if #available(iOS 10.0, *) { 
     let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound] 
     UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
      authOptions, 
      completionHandler: {_,_ in }) 

     // For iOS 10 display notification (sent via APNS) 
     UNUserNotificationCenter.currentNotificationCenter().delegate = self 
     // For iOS 10 data message (sent via FCM) 
     FIRMessaging.messaging().remoteMessageDelegate = self 

    } else { 
     let settings: UIUserNotificationSettings = 
      UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil) 
     application.registerUserNotificationSettings(settings)   
    } 

    application.registerForRemoteNotifications() 

    NotificationCenter.default.addObserver(self, 
              selector: #selector(self.tokenRefreshNotification), 
              name: .firInstanceIDTokenRefresh, 
              object: nil) 

    return true 
}
