iOS应用程序在后台显示通知，但不在前台显示iphone 4s&；操作系统版本9.3

应用程序在未运行状态、后台状态下接收远程通知，并在前台状态下使用本地拦截概念获取通知（获取远程通知时触发本地通知）。但当应用程序位于前台且iOS版本为9.3时，它不会接收远程通知

我的代码在这里：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
        {

        NSLog(@"Called");
        NSLog(@"Response - > %@",userInfo);
        UILocalNotification* localNotification = [[UILocalNotification alloc] init];
        localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
        localNotification.alertBody = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"];
        localNotification.timeZone = [NSTimeZone defaultTimeZone];
        localNotification.applicationIconBadgeNumber = 0;
    }

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification  withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
    {
        NSLog( @"Handle push from foreground" );
        // custom code to handle push while app is in the foreground
        NSLog(@"%@", notification.request.content.userInfo);
        completionHandler(UNNotificationPresentationOptionAlert);
    }

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
    {
        NSLog( @"Handle push from background or closed" );
        // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background
        NSLog(@"%@", response.notification.request.content.userInfo);
        NSInteger countNoti = [[[response.notification.request.content.userInfo valueForKey:@"aps"] valueForKey:@"badge"] integerValue];


        if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive ) {

            UILocalNotification* localNotification = [[UILocalNotification alloc] init];
            localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
            localNotification.alertBody = [[response.notification.request.content.userInfo valueForKey:@"aps"] valueForKey:@"alert"];
            localNotification.timeZone = [NSTimeZone defaultTimeZone];
            localNotification.applicationIconBadgeNumber = countNoti;

            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
        }
    }

调用了DidReceiveMemotentification，但未显示通知。

谢谢。

我想您还没有在AppDelegate文件中实现iOS9推送通知方法

目标-C

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

Swift

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any])

当应用程序处于活动状态时，您可以在上述功能中安排本地通知。显示通知

我想这不是你的错。。我也有同样的问题。。我认为firebase不支持以下内容10@Mansi当应用程序位于前台时，不会显示通知，但您将在DidReceiveNotification操作中获得AppDelegate类的通知，在此您将通过AlertView处理通知。是的，我知道alert view可以解决我的问题，但我不想要警报视图。@AkshayDegadaI认为当应用程序位于前台时，iOS 9不会像iOS 10那样显示任何通知，我认为当应用程序位于前台时，没有任何方式显示通知。也许Darshitvadoria是对的。
