Firebase messaging method swizzling not working - ios

Question

Hi I'm implement FCM (Fire base cloud messaging). I have made the app to receive notification and data from FCM console. I have both my server notification and firebase notification. I want to handle 2 type of notification (from my server and from FCM) separately. I have gone through the docs and this can be achieve by swizzling the notification handler in AppDelegate
But the problem is I can only get FCM message data (IOS 10) in
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {}
and
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {}
The callback for FCM delegate
// The callback to handle data message received via FCM for devices running iOS 10 or above.
- (void)applicationReceivedRemoteMessage:(nonnull FIRMessagingRemoteMessage *)remoteMessage {
// Print full message
NSLog(#"Can get here firebase?%#", [remoteMessage appData]);
}
the above callback is never called
How can we use swizzling to sett up FCM handler message separately?
Here is my Appdelegate didfinishlaunchingwith option
application.applicationIconBadgeNumber = 0;
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
UIUserNotificationType allNotificationTypes =
(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings =
[UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
} else {
// iOS 10 or later
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
UNAuthorizationOptions authOptions =
UNAuthorizationOptionAlert
| UNAuthorizationOptionSound
| UNAuthorizationOptionBadge;
[[UNUserNotificationCenter currentNotificationCenter]
requestAuthorizationWithOptions:authOptions
completionHandler:^(BOOL granted, NSError * _Nullable error) {
}
];
// For iOS 10 display notification (sent via APNS)
[[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];
// For iOS 10 data message (sent via FCM)
[[FIRMessaging messaging] setRemoteMessageDelegate:self];
#endif
}
[[UIApplication sharedApplication] registerForRemoteNotifications];
// [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];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor whiteColor];
_rootViewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
[self.window setRootViewController:_rootViewController];
[self.window makeKeyAndVisible];
NSDictionary *remoteNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (remoteNotification)
[self handleRemoteNotification:remoteNotification shouldPrompt:NO];
self.isFirstTime = true;
self.isJustForRefresh = 0;
return YES;
Anyone know how to make it work?
Edit: here is my observer observation function and didregisterRemoteNotification function
// [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 application 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)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken {
NSString *sanitizedDeviceToken = [[[[deviceToken description]
stringByReplacingOccurrencesOfString:#"<" withString:#""]
stringByReplacingOccurrencesOfString:#">" withString:#""]
stringByReplacingOccurrencesOfString:#" " withString:#""];
DLog(#"sanitized device token: %#", sanitizedDeviceToken);
[PushNotificationManager API_registerAPNSToken:sanitizedDeviceToken
onCompletion:^(BOOL success, NSError *error){}];
[[FIRInstanceID instanceID]setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];
}
Updated: I have include this function but still not working
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
if (userInfo[#"gcm.message_id"] != nil) {
NSLog(#"Should get here FCM?");
[[FIRMessaging messaging]appDidReceiveMessage:userInfo];
}else {
NSLog(#"test fetchCompletion handler: %#",userInfo.description);
}
}

You may take a look of this answer? Seems like you missed the line FIRMessaging.messaging().connect(){....
https://stackoverflow.com/a/40881754/1005570
and also the delegate function..
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: #escaping (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)
FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}
