didReceiveRemoteNotification前景火力云消息不叫于iOS

我试图实现我的应用程序火力点云的消息。didReceiveRemoteNotification前景火力云消息不叫于iOS

我使用下面的代码

if #available(iOS 10.0, *) { 
      // For iOS 10 display notification (sent via APNS) 
      UNUserNotificationCenter.current().delegate = self 

      let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound] 
      UNUserNotificationCenter.current().requestAuthorization(
       options: authOptions, 
       completionHandler: {_, _ in }) 
     } else { 
      let settings: UIUserNotificationSettings = 
       UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil) 
      application.registerUserNotificationSettings(settings) 
     }

，一切工作正常时，应用程序是在回地面注册的通知，但是当应用程序在前台，didReceiveRemoteNotification根本没有被调用。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { 
    // Print message ID. 
    print("please help") 
    if let messageID = userInfo[gcmMessageIDKey] { 
     print("Message ID: \(messageID)") 
    } 

    // Print full message. 
    print(userInfo) 
    completionHandler(.newData) 
}

任何人都知道这个可能的错误？谢谢！

编辑：我不需要看到的通知显示，当应用程序在前台，我只是想从通知

这个完成处理程序根本不能调用吗？ –

是否声明UNUserNotificationCenterDelegate？ – Mohit

的iOS 10.x的处理消息有处理推送通知时，在一个新的功能前景，你应该实现这一个：

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { 

    completionHandler(
     [UNNotificationPresentationOptions.alert, 
     UNNotificationPresentationOptions.sound, 
     UNNotificationPresentationOptions.badge]) 

}

请执行以下方法来接收前景推送通知

对于iOS10，Swift3：

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
{ 
    completionHandler([.alert, .badge, .sound]) 
}

对于iOS10，雨燕2.3：

@available(iOS 10.0, *) 
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) 
{ 
    //Handle the notification 
    completionHandler(
     [UNNotificationPresentationOptions.Alert, 
     UNNotificationPresentationOptions.Sound, 
     UNNotificationPresentationOptions.Badge]) 
}

尝试这一次，

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

    print("Recived: \(userInfo)") 

    completionHandler(.NewData) 

}

我在哪里实施此方法？顺便说一句，iOS 9及以下版本呢？ – progammingBeignner

在appdelegate中执行此操作。对于iOS9及以下版本，您不需要iOS9中的此方法 –

检查是否正常工作。它应该工作我认为。 –

如果使用推送通知火力地堡的IOS 10 请添加此代码。希望能帮助你解决这个问题：

@available(iOS 10, *) 
extension AppDelegate : UNUserNotificationCenterDelegate { 

    // Receive displayed notifications for iOS 10 devices. 
    func userNotificationCenter(_ center: UNUserNotificationCenter, 
           willPresent notification: UNNotification, 
           withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { 
     let userInfo = notification.request.content.userInfo 
     // Print message ID. 
     if let messageID = userInfo[gcmMessageIDKey] { 
      print("Message ID: \(messageID)") 
     } 

     // Print full message. 
     print(userInfo) 
     completionHandler([]) 
    } 

    func userNotificationCenter(_ center: UNUserNotificationCenter, 
           didReceive response: UNNotificationResponse, 
           withCompletionHandler completionHandler: @escaping() -> Void) { 
     let userInfo = response.notification.request.content.userInfo 
     // Print message ID. 
     if let messageID = userInfo[gcmMessageIDKey] { 
      print("Message ID: \(messageID)") 
     } 

     // Print full message. 
     print(userInfo) 
     completionHandler() 
    } 
} 

extension AppDelegate : FIRMessagingDelegate { 
    // Receive data message on iOS 10 devices while app is in the foreground. 
    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) { 
     print(remoteMessage.appData) 
    } 
}
