  • NotifyVisitors-AutoViewRedirection
  • Go to Project Navigator >> App target >> Capabilities
  • Switch on the Background Modes. Select 3 check boxes i.e. Location updates, Background fetch, Remote notifications.


    Switch on the Push Notifications.


    In the Capabilities Tab Turn On App Groups and click on + sign and add a new app group give the group name as group.nv.{Your App Bundle Identifier}.

    Example : if Your App's Bundle Identifier is com.example.myapp then the App Group must be named as make sure this newly created app group must be checked (Turned on)


    Include the header file in .m file in which sdk function is to be accessed.

Import header file

Include the header file in .m files from where sdk functions need to be accessed.

  • iOS

        #import "notifyvisitors.h"    

Initialise the SDK

To initialize the sdk, call the following function in didFinishLaunchingWithOptions method of your project.

  • iOS

        -(BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
            NSString *nvMode = nil;
        #if DEBUG
            nvMode = @"debug";
             nvMode = @"live";
            [notifyvisitors Initialize:nvMode];


Set its value to “debug” or “live” based on preprocessor if condition so that sdk knows the app is running in debugging mode or downloaded from AppStore (i.e. live mode)

Deep Linking

Call the following method in your AppDelegate openURL method that will check the deep linking and open your app from URL Scheme.

  • iOS

        -(BOOL)application:(UIApplication*)application openURL:(NSURL*)url sourceApplication:(NSString*)sourceApplication annotation:(id)annotation {
        [notifyvisitors OpenUrlWithApplication:application Url:url];
        return YES;                               

InApp Notifications

InApp Notifications include both Banners and Surveys. These are displayed based on iOS ViewControllers.

Every event occurs in the context of a ViewController. Every ViewController can be associated with some contextual data, which can be used as targeting rules for In-App Notifications.

Call the below show() Method in viewDidLoad method of every ViewController. show() Method should be called only once per ViewController.

  • iOS

        [notifyvisitors Show:UserToken   CustomRule:CustomRule];   

Default values are passed as nil.

Dynamic Tokens (NSMutableDictionary)Dynamic tokens are used to show personalised content in Notification messages real time.

Custom Rules (NSMutableDictionary)This data can be used in configuring targeting rules for the Notifications.

  • iOS
            [notifyvisitors Show:nil CustomRule:nil];  

            //                      OR   

            NSMutableDictionary *DynamicTokens = [[NSMutableDictionary alloc] init];
                [DynamicTokens setObject:@"Jhon" forKey:@"firstname"];
                [DynamicTokens setObject:@"" forKey:@"email"];

            NSMutableDictionary *CustomRule = [[NSMutableDictionary alloc] init];
            [CustomRule setObject:@"fation" forKey:@"category"];
            [CustomRule setObject:@"2000" forKey:@"price"];

            [notifyvisitors Show:DynamicTokens   CustomRule:CustomRule ];

If you are using UIScrollView call the following method in your ScrollViewDidScroll delegate method.

  • iOS

        -(void)scrollViewDidScroll:(UIScrollView *)scrollView {
        [notifyvisitors scrollViewDidScroll:scrollView];          

Push Notifications

  1. Add the following method in didFinishLaunchingWithOptions method of application.
  • iOS

         [notifyvisitors RegisterPushWithDelegate:self App:application launchOptions:launchOptions];
  1. Add the following methods inside your AppDelegate file to handle the registering and receiving events of push notification.
  • iOS

        -(void)application: (UIApplication*) application didRegisterForRemoteNotificationsWithDeviceToken: (NSData *)deviceToken  {
            [notifyvisitors DidRegisteredNotification:application deviceToken:deviceToken];    

        -(void)application: (UIApplication*)application didFailToRegisterForRemoteNotificationsWithError: (NSError *)error {
        -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
            [notifyvisitors didReceiveRemoteNotificationWithUserInfo:userInfo];

Add the following method in application applicationWillTerminate in your AppDelegate file.

  • iOS

         [notifyvisitors applicationWillTerminate];
  1. For iOS 10 Push Notification, Add the following Delegate Methods in AppDelegate file.

a.) Go to AppDelegate.h and import UserNotifications framework.

  • iOS

         #import <UserNotifications/UserNotifications.h>
         @interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>

b.) Go to AppDelegate.m file and add the following delegate methods

  • iOS

        # pragma mark UNNotificationCenter Delegate Methods
        - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler {
          [notifyvisitors willPresentNotification:notification withCompletionHandler:completionHandler];
        - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {

            [notifyvisitors didReceiveNotificationResponse:response];  
        - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
            [notifyvisitors didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];    

c.) Add Notification Service Extension to support Rich media Attachment in iOS 10 push notification. Kindly refer to our Notification Service Extension creation guide.

Notification Center

You can show a list of push notifications received in an In-app Notification Center. Expiry of the notifications can be set from the panel.

To launch In-app notification center you can call the following method.

  • iOS

        [notifyvisitors NotifyVisitorsNotificationCentre]; 


  1. To handle the geofencing notifications in background state and Inactive state of application, add the following codes in applicationDidEnterBackground and applicationDidBecomeActive methods respectively.
  • iOS

        - (void)applicationDidEnterBackground:(UIApplication *)application {
            [notifyvisitors NotifyVisitorsGeofencingApplicationDidEnterBackground];      
        - (void)applicationDidBecomeActive:(UIApplication *)application {
         [notifyvisitors NotifyVisitorsGeofencingapplicationDidBecomeActive];      
  1. Add the following Code to receive local notification when geofencing events trigger.
  • iOS

        -(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *) notification {
        [notifyvisitors NotifyVisitorsGeofencingReceivedNotificationWithApplication:application window:self.window didReceiveGeofencingNotification:notification];                         

Track Users

User API enables you to track a users' activity as they move from device to device and attach attributes to their profiles. Attributes enrich user profiles, like email, username, mobile, gender etc.This method should be called when the user is identified (mostly on login).

  • iOS

        [notifyvisitors UserIdentifier:@"userID"   jsonData:jsonDataMutableDictionary];

USER_ID Setting the Unique ID is a critical piece to tie a user across devices and installs/uninstalls as well across all platforms (i.e. iOS, Android, Windows, The Web). Unique ID can be something like an email ID, a username (unique), or any Backend generated ID.

USER_ATTRIBUTES (jsonDataMutableDictionary) You can set the user attributes like name, email, mobile number. These can then be used to send personalised content in notifications. But these attributes can not be used in segmenting the users.

Default Attribute Names -

  • name
  • email
  • mobile

You can also pass your custom attributes like username, birthday, first name, last name.


Attribute Names should contain only alpha-numerics, white spaces or ‘_’ ;
No other special characters are allowed.
Recommended names - ‘first_name’, ‘last_name’

Sample Code

  • iOS

        NSMutableDictionary *userParameters = [[NSMutableDictionary alloc] init];
            [userParameters setObject:@"Jhon" forKey:@"name"];
            [userParameters setObject:@"" forKey:@"email"];
            [userParameters setObject:@"9818XXXXXX" forKey:@"mobile"];

            [notifyvisitors UserIdentifier:@"userID" UserParams:userParameters];

Track Events

Event API enables you to record any actions your users perform, along with any properties that describe the action. These are then used for analytics, user segmentation or to trigger engagements or other actions.

  • iOS

        [notifyvisitors trackEvents:@”eventName” Attributes:AttributesDictionary lifetimeValue:@”Ltv” Scope:scope ];

EVENT_NAME (string)Name of the event like sale, register. Event names should contain only alpha-numerics, white spaces or ‘_’ ; No other special characters are allowed.

EVENT_ATTRIBUTES (NSMutableDictionary)Attributes associated with the event. Attribute values should be passed in the form of Javascript strings, booleans and numbers respectively. Similarly date attribute values are expected in the form of Javascript date objects.


Attribute Names should contain only alpha-numerics, white spaces or ‘_’ ; No other special characters are allowed. Recommended names - ‘category’, ‘price_usd’

LIFETIME_VALUE (integer)The score you would like to reward the user on performing this event like 10, 100.

SCOPE (integer) The scope of the event, whether it should be tracked every time it is called, or per session, or once in a lifetime. This parameter is used to minimise the duplication of data in analytics. It is an integer whose values are :

  1. Track every time the api is called
  2. Track once per session
  3. Track once in a lifetime

Sample Code

  • iOS

        NSMutableDictionary *AttributesDictionary = [[NSMutableDictionary alloc] init];
            [AttributesDictionary setObject:@"2000" forKey:@"price"];
            [AttributesDictionary setObject:@"fancy" forKey:@"Category"];

            [notifyvisitors trackEvents:@"eventName" Attributes:AttributesDictionary lifetimeValue:@"100" Scope:1];
