Push Notifications API for PubNub Objective-C SDK

PubNub's Mobile Push Gateway feature enables developers to bridge native PubNub publishing with 3rd-party push notification services including Google Android FCM (Firebase Cloud Messaging) and Apple iOS APNs (Apple Push Notification service).

By using the Mobile Push Gateway, developers can eliminate the need for developing, configuring, and maintaining additional server-side components for third-party push notification providers.

To learn more, read about Push Notifications.

APNs version support

PubNub Objective-C SDK supports both the HTTP/2-based Apple Push Notification service (APNs) and the already deprecated legacy binary protocol for APNs Push Notifications. Depending on the APNs version you use in your SDK, set pushType in methods to either PNAPNS2Push or PNAPNSPush.

Removing Device From Channel (Builder Pattern)

Requires Mobile Push Notifications add-onRequires that you enable the Mobile Push Notifications for your key. Refer to the following page for details on enabling add-on features on your keys:
https://support.pubnub.com/hc/en-us/articles/360051974791-How-do-I-enable-add-on-features-for-my-keys-

Description

Disable push notifications on a provided set of channels.

Method(s)

To run Removing Device From Channel, you can use the following method(s) in the Objective-C SDK
APNS2 Token:

push().disable().channels(NSArray<NSString *> *).token(id).pushType(PNPushType).environment(PNAPNSEnvironment).topic(NSString *).performWithCompletion(nullable PNPushNotificationsStateModificationCompletionBlock)

Parameter	Type	Required	Description
channels	NSArray<NSString *> *	Yes	List of channel names for which push notifications should be disabled.
token	id	Yes	Device token / identifier that you must set to either NSData.
pushType	PNPushType	Yes	One of PNPushType fields which specify service to manage notifications for device specified with pushToken. Available push types: PNAPNS2Push - Apple Push Notification service over HTTP/2
environment	PNAPNSEnvironment	No	One of PNAPNSEnvironment fields which specify environment within which device should manage list of channels with enabled notifications (works only if pushType set to PNAPNS2Push).
topic	NSString	No	Notifications topic name (usually it is application's bundle identifier).
block	PNPushNotificationsStateModificationCompletionBlock	No	Remove notifications from channels request completion block.

Note

This method uses the builder pattern, you can remove the arguments which are optional.

FCM Token:

push().disable().channels(NSArray<NSString *> *).fcmToken(NSString *).performWithCompletion(PNPushNotificationsStateModificationCompletionBlock)

Parameter	Type	Required	Description
channels	NSArray<NSString *> *	Yes	List of channel names for which push notifications should be disabled. If the passed list is empty, all notifications will be disabled.
fcmToken	NSString *	Yes	FCM-provided device push token which should be used to disable push notifications on a specified set of channels.
completion	PNPushNotificationsStateAuditCompletionBlock	No	Push notifications removal from channels processing completion block which pass only one argument - request processing status to report about how data pushing was successful or not.

Note

This method uses the builder pattern, you can remove the arguments which are optional.

Basic Usage

APNS2 Token:

self.client.push().disable()
    .token(self.devicePushToken)
    .channels(@[@"wwdc",@"google.io"])
    .pushType(PNAPNS2Push)
    .environment(PNAPNSProduction)
    .topic(@"com.my-application.bundle")
    .performWithCompletion(^(PNAcknowledgmentStatus *status) {
        if (!status.isError) {
            // Push notification successfully disabled on passed channels.
        } else {
            /**
             * Handle modification error. Check 'category' property to find out possible issue because
             * of which request did fail.
             *
             * Request can be resent using: [status retry];
             */
        }
    });

FCM Token:

self.client.push().disable()
    .channels(@[@"channel1", @"channel2"])
    .fcmToken(self.pushToken)
    .performWithCompletion(^(PNAcknowledgmentStatus *status) {
        if (!status.isError) {
           // Handle successful push notification enabling on passed channels.
        } else {
           /**
            Handle modification error. Check 'category' property
            to find out possible reason because of which request did fail.
            Review 'errorData' property (which has PNErrorData data type) of status
            object to get additional information about issue.

            Request can be resent using: [status retry];
            */
        }
    });

@interface PNErrorData : PNServiceData

// Stringified error information.
@property (nonatomic, readonly, strong) NSString *information;

@end

@interface PNAcknowledgmentStatus : PNErrorStatus
