【问题描述】：

我正在尝试在我的应用处于前台时显示本地通知。显示远程通知没有问题，但是当应用程序在前台运行时出现问题。我只是在使用新的 ios 10 时遇到问题。

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) 
    // TODO: Handle data of notification

if application.applicationState == UIApplicationState.Active 
    //print("Message ID: \(userInfo["gcm.message_id"]!)")
    //print("Message ID: \(userInfo.keys)")
        dispatch_async(dispatch_get_main_queue(),  () -> Void in

            if (userInfo["notice"] != nil) 

                if #available(iOS 10.0, *) 

                    print ("yes")

                    let content = UNMutableNotificationContent()
                    content.title = "My Car Wash"
                    content.body = (userInfo["notice"] as? String)!
                

                else
                
                    let localNotification = UILocalNotification()
                    localNotification.fireDate = NSDate(timeIntervalSinceNow:0)
                    localNotification.alertBody = userInfo["notice"] as? String
                    localNotification.soundName = UILocalNotificationDefaultSoundName

                    localNotification.alertAction = nil
                    localNotification.timeZone = NSTimeZone.defaultTimeZone()
                    UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
                    let systemSoundID: SystemSoundID = 1000
                    // to play sound
                    AudioServicesPlaySystemSound (systemSoundID)
                    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
                    completionHandler(.NewData)
                

            

        )

我的 iPhone 运行的是 iOS 10，我可以看到打印出“是”。我的应用具有所需的通知权限。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
        // Register for remote notifications
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
        // [END register_for_notifications]
        FIRApp.configure()
        // Add observer for InstanceID token refresh callback.
        NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification),
                                                         name: kFIRInstanceIDTokenRefreshNotification, object: nil)
        return true
    

正如在 iOS 9 设备上所提到的，代码可以正常工作，并且当应用程序未运行时我会收到通知。当应用程序处于前台时，问题出在 iOS 10 上。我已经在谷歌搜索了一段时间，但我仍然不在那里。任何帮助或建议将不胜感激。

【参考方案1】：

您的代码在 iOS10 中不起作用，必须使用

UserNotifications 框架

对于运行 iOS 9 及更低版本的设备，实现 AppDelegate application:didReceiveRemoteNotification: 以处理客户端应用在前台时收到的通知

对于运行 iOS 10 及更高版本的设备，实现

UNUserNotificationCenterDelegate userNotificationCenter:willPresentNotification:withCompletionHandler:

当客户端应用程序在前台时处理收到的通知（从这里https://firebase.google.com/docs/notifications/ios/console-audience）

您的代码必须是这样的（对于 Firebase 通知）：

import UIKit
import UserNotifications

import Firebase
import FirebaseInstanceID
import FirebaseMessaging

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate 

  var window: UIWindow?

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

    // [START register_for_notifications]
    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()
    


    // [END register_for_notifications]

    FIRApp.configure()

    // Add observer for InstanceID token refresh callback.
    NSNotificationCenter.defaultCenter().addObserver(self,
        selector: #selector(self.tokenRefreshNotification),
        name: kFIRInstanceIDTokenRefreshNotification,
        object: nil)

    return true
  

  // [START receive_message]
  func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                   fetchCompletionHandler completionHandler: (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

    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")

    // Print full message.
    print("%@", userInfo)
  
  // [END receive_message]

  // [START refresh_token]
  func tokenRefreshNotification(notification: NSNotification) 
    if let refreshedToken = FIRInstanceID.instanceID().token() 
      print("InstanceID token: \(refreshedToken)")
    

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

  // [START connect_to_fcm]
  func connectToFcm() 
    FIRMessaging.messaging().connectWithCompletion  (error) in
      if (error != nil) 
        print("Unable to connect with FCM. \(error)")
       else 
        print("Connected to FCM.")
      
    
  
  // [END connect_to_fcm]

  func applicationDidBecomeActive(application: UIApplication) 
    connectToFcm()
  

  // [START disconnect_from_fcm]
  func applicationDidEnterBackground(application: UIApplication) 
    FIRMessaging.messaging().disconnect()
    print("Disconnected from FCM.")
  
  // [END disconnect_from_fcm]


// [START ios_10_message_handling]
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate 

  // Receive displayed notifications for iOS 10 devices.
  func userNotificationCenter(center: UNUserNotificationCenter,
                              willPresentNotification 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)
  


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


// [END ios_10_message_handling]
