iOS invalid deviceToken

Question

I'm trying to get iOS device token use code:

if ([[UIDevice currentDevice].systemVersion floatValue] >= 10.0) {
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
    UNUserNotificationCenter *center = [UNUserNotificationCenter          currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge |       UNAuthorizationOptionSound | UNAuthorizationOptionAlert |      UNAuthorizationOptionCarPlay) completionHandler:^(BOOL granted, NSError *_Nullable error) {
        if (!error) {
            NSLog(@"request authorization succeeded!");
        }
    }];

    [[UIApplication sharedApplication] registerForRemoteNotifications];
    #else
    UIUserNotificationType types = (UIUserNotificationTypeAlert |    UIUserNotificationTypeSound | UIUserNotificationTypeBadge);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
#endif
} else if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
    UIUserNotificationType types = (UIUserNotificationTypeAlert | UIUserNotificationTypeSound | UIUserNotificationTypeBadge);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
} else {
    UIRemoteNotificationType apn_type = (UIRemoteNotificationType)    (UIRemoteNotificationTypeAlert |
                                                                   UIRemoteNotificationTypeSound |
                                                                   UIRemoteNotificationTypeBadge);
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:apn_type];
}

Note : Require to add push Notification Certificate in your Project

If you have add push Notification certificate than

Try This :

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

 if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
    {
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [[UIApplication sharedApplication] registerForRemoteNotifications];
    }
    else
    {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
    }

}

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

    self.AppDeviceToken=[[NSString alloc] initWithFormat:@"%@",deviceToken];
    //NSLog(@"My token is: %@", self.AppDeviceToken);

    self.AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@" " withString:@""];
    self.AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@"<" withString:@""];
    self.AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@">" withString:@""];

    NSLog(@"%@'s Device Token is : %@",[[UIDevice currentDevice] name],self.AppDeviceToken);
}

In iOS 10.0 or Greater

#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    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){
                [[UIApplication sharedApplication] registerForRemoteNotifications];
            }
        }];
    }
}

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings: (UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
    NSLog(@"User Info : %@",notification.request.content.userInfo);
    completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
    NSLog(@"User Info : %@",response.notification.request.content.userInfo);
    completionHandler();
}

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    self.AppDeviceToken=[[NSString alloc] initWithFormat:@"%@",deviceToken];
    //NSLog(@"My token is: %@", self.AppDeviceToken);

    self.AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@" " withString:@""];
    self.AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@"<" withString:@""];
    self.AppDeviceToken = [self.AppDeviceToken stringByReplacingOccurrencesOfString:@">" withString:@""];

    NSLog(@"%@'s Device Token is : %@",[[UIDevice currentDevice] name],self.AppDeviceToken);
}
