ios - 为什么设备在后台收不到推送通知？

Question

在 iOS10 上，当应用程序打开时我收到推送通知，但是当我按下主页按钮并且应用程序处于后台模式时 - 它没有收到任何信息。

我的代码是:

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate {

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if #available(iOS 10.0, *) {
        let authOptions: UNAuthorizationOptions = [.Alert, .Badge, .Sound]
        UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Sound, .Alert, .Badge], completionHandler: { (granted: Bool, error: NSError?) 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)
    }

// Connect to FCM since connection may have failed when attempted before having a token.
    connectToFcm()

    application.registerForRemoteNotifications()

}
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    let userInfo = notification.request.content.userInfo

}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
    //Handle the notification
    print("User Info => ",response.notification.request.content.userInfo)
    completionHandler()
}

所以我找不到问题出在哪里？任何想法？还是iOS10有什么新东西？
