为什么重新安装iOS应用程序后Firebase消息无法正常工作？

我刚刚正确地实现了Firebase，在我卸载应用程序并从Xcode再次运行之前，它工作得非常好。从那时起，它不会收到任何Firebase通知，无论是背景还是前景。怎么可能呢？所有的证书似乎都没问题。这是我的AppDelegate.m：

@import Firebase;
@import FirebaseInstanceID;
@import FirebaseMessaging;

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    UIPageControl *pageControl = [UIPageControl appearance];
    pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
    pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
    pageControl.backgroundColor = [UIColor whiteColor];

    // Use Firebase library to configure APIs
    [FIRApp configure];

    // Managing notifications:

    if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0")){
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
             if(!error){
                 [self registerForNotification];
             }
         }];

    } else {
        if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)]){

            // iOS 8 Notifications:

            [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

            [application registerForRemoteNotifications];

            [self registerForNotification];

        } else {

            // iOS < 8 Notifications

            [application registerForRemoteNotificationTypes:
             (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
        }
    }

    return YES;
}

  // TODO: Handle data of notification

  // Print message ID.
  NSLog(@"Message ID: %@", userInfo[@"gcm.message_id"]);

  // Print full message.
  NSLog(@"%@", userInfo);
}

                        forContext:UIUserNotificationActionContextDefault];

        NSSet *categories = [NSSet setWithObject:actionCategory];
        UIUserNotificationType types = (UIUserNotificationTypeAlert|
                                        UIUserNotificationTypeSound|
                                        UIUserNotificationTypeBadge);

谢谢！

代码很好，没有错误。这似乎是谷歌服务器的同步问题或其他问题。这发生在我身上，在安装应用程序1小时后开始工作

请稍等：）

以防万一，可能会使某人受益，缺少的部分是：

      - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

    // for development 
        [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];

    // for production 
   //     [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeProd];

}

您是通过控制台还是从自己的应用服务器发送通知？通过Firebase控制台
