推送通知未在iOS 10中显示

Question

如何在iOS 10中收到通知？在以前的版本中，我可以在func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject])收到通知。

在iOS 10中，Apple引入了UNNotificationSettings。我可以使用func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage)获取FCM。

但是，我无法在后台显示手机通知。

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)
}
}

你必须移动这个方法

application.registerForRemoteNotifications（）

以上返回声明。

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
 }
