Configure required iOS packages

The package is automatically linked when building the app. All you need to do is to install the native pods:

npx pod-install

Configure Info.plist and Entitlements.plist

1. Go into your "PushDemo/ios" folder and open "PushDemo.xcworkspace" workspace, select the top project "PushDemo" and select the "Signing & Capabilities" tab.

2. Update Bundle Identifier to match the value used in the provisioning profile.

3. Add two new Capabilities using the - "+" button:

   • Background Mode capability and tick Remote Notifications.
   • Push Notifications capability

Handle push notifications for iOS

1. Open "AppDelegate.h" and add the following import:

   #import <UserNotifications/UNUserNotificationCenter.h>

2. Update list of protocols, supported by the "AppDelegate", by adding UNUserNotificationCenterDelegate:

   @interface AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeDelegate, UNUserNotificationCenterDelegate>

3. Open "AppDelegate.m" and configure all the required iOS callbacks:

   #import <UserNotifications/UserNotifications.h>
   #import <RNCPushNotificationIOS.h>
   
   ...
   
   // Required to register for notifications
   - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
   {
    [RNCPushNotificationIOS didRegisterUserNotificationSettings:notificationSettings];
   }
   
   // Required for the register event.
   - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
   {
    [RNCPushNotificationIOS didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
   }
   
   // Required for the notification event. You must call the completion handler after handling the remote notification.
   - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
   fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
   {
     [RNCPushNotificationIOS didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
   }
   
   // Required for the registrationError event.
   - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
   {
    [RNCPushNotificationIOS didFailToRegisterForRemoteNotificationsWithError:error];
   }
   
   // IOS 10+ Required for localNotification event
   - (void)userNotificationCenter:(UNUserNotificationCenter *)center
   didReceiveNotificationResponse:(UNNotificationResponse *)response
            withCompletionHandler:(void (^)(void))completionHandler
   {
     [RNCPushNotificationIOS didReceiveNotificationResponse:response];
     completionHandler();
   }
   
   // IOS 4-10 Required for the localNotification event.
   - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
   {
    [RNCPushNotificationIOS didReceiveLocalNotification:notification];
   }
   
   //Called when a notification is delivered to a foreground app.
   -(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
   {
     completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
   }
