iOS Firebase Push Notifications not receive in device using obj c - ios

Question

Integrate Firebase cloud messaging in my application. Successfully install pod and get all the framework. I want to get the refreshedToken for my device and send the notification and receive in my device, and want to track all the button click in my app.

I'm using this code in app delegate. Got these waring in my code. How can I fix this issues. new for development help me.

Use the following Swift code.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
if #available(iOS 10.0, *)
{
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
if granted
{
//self.registerCategory()
}
}
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
}
else
{
let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert,.Badge,.Sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
//Configuring Firebase
FIRApp.configure()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil)
return true
}
//Receive Remote Notification on Background
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)
{
FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
{
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Prod)
}
func tokenRefreshNotification(notification: NSNotification)
{
if let refreshedToken = FIRInstanceID.instanceID().token()
{
print("InstanceID token: \(refreshedToken)")
}
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
func connectToFcm()
{
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil)
{
print("Unable to connect with FCM. \(error)")
}
else
{
print("Connected to FCM.")
}
}
}
func applicationDidBecomeActive(application: UIApplication)
{
connectToFcm()
}

Have you set up the application correctly on the Firebase dashboard?
I have encountered this error before, as the Cloud Messaging settings aren't too obvious on the Firebase console.
Open the Firebase console. Click the cog next to your application name and go on "Project Settings".
Select the cloud messaging tab. You'll need to add your iOS APNS certificates here to successfully send push messages (One for development, one for production).
I was getting this error as I hadn't correctly uploaded my apps certificates.
Update:
Another reason for this error that i've encountered this error is that the Firebase SDK sometimes can't obtain the APNS token from apple itself. To resolve this, i've obtained the token manually:
First register for remote notifications:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
...
// Register for remote notifications.
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
When the APNS token is returned, manually set it on the Firebase instance:
- (void)application:(UIApplication *)app
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
NSLog(#"Registered for notification device token: %#", devToken);
[[FIRInstanceID instanceID] setAPNSToken:devToken type:FIRInstanceIDAPNSTokenTypeUnknown];
[self connectToFcm];
const void *devTokenBytes = [devToken bytes];
}
Should then successfully be able to connect to Firebase cloud messaging:
- (void)connectToFcm {
NSLog(#"Connecting to FCM...");
[[FIRMessaging messaging] connectWithCompletion:^(NSError * _Nullable error) {
if (error != nil) {
NSLog(#"Unable to connect to FCM. %#", error);
} else {
NSLog(#"Connected to FCM.");
}
}];
}
If you cannot obtain the APNS token this way, there is something wrong with your push notification setup on the apple member center. Have you generated a developer/release APNS certificate and added them to your provision profile?
