Unable to get notification by FCM on real device - ios

Question

i have already add APNs certificate on firebase..but when i send notification from FCM my device not showing any notification and also InstanceID and messageID gives null in the output
here is my app delegate.m code
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
sleep(3);
SplitsVC*log=[[SplitsVC alloc] initWithNibName:#"SplitsVC" bundle:nil];
self.navVC=[[MyNavigationController alloc] initWithRootViewController:log];
[self.navVC.navigationBar setHidden:YES];
[self.window setRootViewController:self.navVC];
[self.window makeKeyAndVisible];
// Add observer to listen for the token refresh notification.
// Register for remote notifications
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1) {
// iOS 7.1 or earlier
UIRemoteNotificationType allNotificationTypes =
(UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge);
[application registerForRemoteNotificationTypes:allNotificationTypes];
} else {
// iOS 8 or later
// [START register_for_notifications]
UIUserNotificationType allNotificationTypes =
(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings =
[UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];
// [END register_for_notifications]
}
// [START configure_firebase]
[FIRApp configure];
// [END configure_firebase]
// Add observer for InstanceID token refresh callback.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(tokenRefreshNotification:)
name:kFIRInstanceIDTokenRefreshNotification object:nil];
return YES;
}
// [START receive_message]
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
// 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.
NSLog(#"Message ID: %#", userInfo[#"gcm.message_id"]);
// Pring full message.
NSLog(#"%#", userInfo);
}
// [END receive_message]
// [START refresh_token]
- (void)tokenRefreshNotification:(NSNotification *)notification {
// Note that this callback will be fired everytime a new token is generated, including the first
// time. So if you need to retrieve the token as soon as it is available this is where that
// should be done.
NSString *refreshedToken = [[FIRInstanceID instanceID] token];
NSLog(#"InstanceID token: %#", refreshedToken);
// Connect to FCM since connection may have failed when attempted before having a token.
[self connectToFcm];
// TODO: If necessary send token to appliation server.
}
// [END refresh_token]
// [START connect_to_fcm]
- (void)connectToFcm {
[[FIRMessaging messaging] connectWithCompletion:^(NSError * _Nullable error) {
if (error != nil) {
NSLog(#"Unable to connect to FCM. %#", error);
} else {
NSLog(#"Connected to FCM.");
}
}];
}
// [END connect_to_fcm]
- (void)applicationDidBecomeActive:(UIApplication *)application {
[self connectToFcm];
}
// [START disconnect_from_fcm]
- (void)applicationDidEnterBackground:(UIApplication *)application {
[[FIRMessaging messaging] disconnect];
NSLog(#"Disconnected from FCM");
}
// [END disconnect_from_fcm]
and this is output-

Please make sure the certificate which is up on firebase and the one you are using in xcode is same . And also please try to look at the documentation of Firebase.
