I'm trying to add Firebase SDK to my app. On Android side it's all good and works as expected. On iOS side it works that way I can make it receive messages via FCM, but cannot get APNs token at all. Sounds like easy problem/mistake?
Firebase iOS SDK 5.17 and Firebase C++ SDK 5.5.0 are added and compiled in. I included following frameworks:
firebase.framework
firebase_instance_id.framework
firebase_messaging.framework
FirebaseCore.framework
FirebaseInstanceID.framework
FirebaseMessaging.framework
GoogleUtilities.framework
Protobuf.framework
info.plist contains:
<key>FirebaseAppDelegateProxyEnabled</key>
<false/>
Yes, I need to disable method swizzling coz I need APNs token.
Now in didRegisterForRemoteNotificationsWithDeviceToken:
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken {
[FIRMessaging messaging].APNSToken = deviceToken;
Of course Xcode project is all fine: provision profile is active, Target -> Background Modes -> Remote notifications -> Enabled, Target -> Push notifications -> ON. GoogleService-Info.plist is added to project.
What's wrong? When Firebase SDK added and method swizzling disabled, didRegisterForRemoteNotificationsWithDeviceToken and didFailToRegisterForRemoteNotificationsWithError are never ever called. I tried to call:
[[UIApplication sharedApplication] registerForRemoteNotifications]
but no luck. Tried
requestAuthorizationWithOptions
and
if(granted) {
[[UIApplication sharedApplication] registerForRemoteNotifications]
still nothing.
I missed something but I think it's either too simple or too difficult to find for me. Wasted two days to find but still no idea.
UPDATE: I reproduced a problem in empty Objective-C project. It occurs when both Firebase iOS SDK and Firebase C++ SDK are implemented. If I remove Firebase C++ SDK frameworks, I can get my token again. Now when I can't get token I get "ERROR: Attempting to complete future before FCM initialized." in log.
Reproduce steps:
- Create Xcode project as usual. In my case it's a Game. Using Objective-C, Metal.
- On Capabilities->Background Modes->ON and Background Modes->Remote Notifications->Checked.
- Capabilities->Push Notifications->ON. Xcode shows enabled and no problems.
- On Firebase Console, created new app; added iOS app, bundle ID->download GoogleService-Info.plist and added to app.
- I don't use Cocoa Pods, so add following SDKs to iOS project: firebase.framework, firebase_instance_id.framework, firebase_messaging.framework, FirebaseCore.framework, FirebaseInstanceID.framework, FirebaseMessaging.framework, GoogleUtilities.framework, Protobuf.framework. These are frameworks from Firebase iOS SDK 5.17 and Firebase C++ SDK 5.5.0.
- Add UserNotifications.framework to project as Optional.
- Set iOS Deployment target to 9.0.
- Login to Apple Developer and create authentication key, and register it to Firebase console.
In AppDelegate.m:
import "FirebaseCore/FIRApp.h"
import "FirebaseMessaging/FIRMessaging.h"
import
@interface AppDelegate () //<-added UNUserNotificationCenterDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [FIRApp configure]; if ([UNUserNotificationCenter class] != nil) { [UNUserNotificationCenter currentNotificationCenter].delegate = self; UNAuthorizationOptions authOptions = UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge; [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:authOptions completionHandler:^(BOOL granted, NSError * _Nullable error) { printf("requestAuthorizationWithOptions granted=%d", granted); }]; } else { UIUserNotificationType allNotificationTypes = (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge); UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil]; [application registerUserNotificationSettings:settings]; } [application registerForRemoteNotifications];
Add methods to AppDelegate:
(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { [FIRMessaging messaging].APNSToken = deviceToken; printf("didRegisterForRemoteNotificationsWithDeviceToken called!"); }
(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { printf("didFailToRegisterForRemoteNotificationsWithError"); }
- In Info.plist add FirebaseAppDelegateProxyEnabled , type Boolean , set value to NO.
- Add -ObjC to target -> Other Linker Flags
- Add FirebaseImplement.cpp with hpp header to project. cpp contains only include hpp line.
- Run app. Log: 2019-02-26 14:56:37.695107+0900 fcmtest2[821:126237] [DYMTLInitPlatform] platform initialization successful 2019-02-26 14:56:37.734503+0900 fcmtest2[821:126088] FIID: Loading UIApplication FIRIID category 2019-02-26 14:56:37.791910+0900 fcmtest2[821:126088] FCM: Loading UIApplication FIRFCM category 2019-02-26 14:56:37.971120+0900 fcmtest2[821:126088] Setting up iOS 10 message delegate. 2019-02-26 14:56:37.987322+0900 fcmtest2[821:126233] 5.17.0 - [Firebase/Core][I-COR000022] Firebase Analytics is not available.

- And neither didRegisterForRemoteNotificationsWithDeviceToken nor didFailToRegisterForRemoteNotificationsWithError are called.
