How to implement interactive remote notifications in iOS Objective-c

Question

I am new in Objective-c. I want to create a interactive remote notification which have two action, one is call 'OK' and another is called 'VIEW'. When user receive notification through APNS that time if user click 'OK' the notification have to be dismiss and if user click 'VIEW' that time open a particular page of my app. That's it.

I have go through many web documents and grab some concept of notification payload. But I am not able to implement this step wise. Can any one assist me, how can I implement this functionality. And please anyone don't mark as a duplicate question. Thanks

hi @Prashant, your provided document is applicable for upper version of iOS. like iOS10,11? — Swarup, Dec 05 '17 at 09:55
@PrashantTukadiya, one more question, it's for remote notification, right? — Swarup, Dec 05 '17 at 10:25
@PrashantTukadiya, so from backend we need only "category" : "Any String"? Please clarify it will be more helpful for me. — Swarup, Dec 05 '17 at 11:01
@Swarup yes that's all you need it !! see this https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CreatingtheNotificationPayload.html — Prashant Tukadiya, Dec 05 '17 at 11:17
@PrashantTukadiya, I have not enough reputation for discussion to chat. If i wnt to dismiss a notification by clicking one of the button called 'OK' that time which code to write in method of "handleActionWithIdentifier"? It's a last question. Thanks for your assistant. — Swarup, Dec 05 '17 at 11:25

Note: I have use my own constants here for category like KNotificatoin_IDENTIFIER_CATEGORY_NEW_BID use your at that place

Register for push

- (void) registerPushNotification {

    UIUserNotificationType  type = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge |  UIUserNotificationTypeSound;
    UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:type categories:[NSSet setWithObjects:[self createActionNotificationsSettingForApproveBID],[self createActionNotificationsSettingForCancelingRequest ], nil]];
    [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

}


- (UIMutableUserNotificationCategory *) createActionNotificationsSettingForApproveBID {

    UIMutableUserNotificationAction *actionApproveBID = [[UIMutableUserNotificationAction alloc]  init];
    [actionApproveBID setIdentifier:KNotificatoin_IDENTIFER_ACTION_APPROVEBID];
    actionApproveBID.activationMode = UIUserNotificationActivationModeForeground;
    actionApproveBID.title = @"Approve";
    actionApproveBID.authenticationRequired = true;
    [actionApproveBID setDestructive: false];


    UIMutableUserNotificationAction *actionCancelDialog = [[UIMutableUserNotificationAction alloc]  init];
    [actionCancelDialog setIdentifier:KNotificatoin_IDENTIFER_ACTION_DETAILS];
    actionCancelDialog.activationMode = UIUserNotificationActivationModeForeground;
    actionCancelDialog.title = @"Details";
    actionCancelDialog.authenticationRequired = true;
    [actionCancelDialog setDestructive: false];

    UIMutableUserNotificationCategory *cateogoryApproveBID = [[UIMutableUserNotificationCategory alloc] init];
    cateogoryApproveBID.identifier = KNotificatoin_IDENTIFIER_CATEGORY_NEW_BID;
    [cateogoryApproveBID setActions:@[actionApproveBID,actionCancelDialog] forContext:UIUserNotificationActionContextDefault];
    [cateogoryApproveBID setActions:@[actionApproveBID,actionCancelDialog] forContext:UIUserNotificationActionContextMinimal];

    return cateogoryApproveBID;
}

- (UIMutableUserNotificationCategory *) createActionNotificationsSettingForCancelingRequest {

    UIMutableUserNotificationAction *actionGetMoreBids = [[UIMutableUserNotificationAction alloc]  init];
    [actionGetMoreBids setIdentifier:KNotificatoin_IDENTIFER_ACTION_APPROVEBID];
    actionGetMoreBids.activationMode = UIUserNotificationActivationModeForeground;
    actionGetMoreBids.title = @"Get more bids";
    actionGetMoreBids.authenticationRequired = true;
    [actionGetMoreBids setDestructive: false];


    UIMutableUserNotificationAction *actionEditRequest = [[UIMutableUserNotificationAction alloc]  init];
    [actionEditRequest setIdentifier:KNotificatoin_IDENTIFER_ACTION_EDIT_REQUEST];
    actionEditRequest.activationMode = UIUserNotificationActivationModeForeground;
    actionEditRequest.title = @"Edit request";
    actionEditRequest.authenticationRequired = true;
    [actionEditRequest setDestructive: false];

    UIMutableUserNotificationCategory *categoryCancelRequest = [[UIMutableUserNotificationCategory alloc] init];
    categoryCancelRequest.identifier = KNotificatoin_IDENTIFER_ACTION_MORE_BIDS;
    [categoryCancelRequest setActions:@[actionGetMoreBids,actionEditRequest] forContext:UIUserNotificationActionContextDefault];
    [categoryCancelRequest setActions:@[actionGetMoreBids,actionEditRequest] forContext:UIUserNotificationActionContextMinimal];

    return categoryCancelRequest;
}

How you will handle actions ?

- (void) application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler {
    NSLog(@" APPLICATION STATUS %ld",(long)[UIApplication sharedApplication].applicationState);

    if ([[[userInfo objectForKey:@"aps"] objectForKey:kCategory] isEqualToString:KNotificatoin_IDENTIFIER_CATEGORY_NEW_BID]){
        if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_APPROVEBID]) {
            NSMutableDictionary *dictData = [NSMutableDictionary dictionaryWithDictionary:userInfo];
            [dictData setObject:@17 forKey:kType];

            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:dictData];
            } else {
                [self navigatateAsPerPush:dictData allowInActiveState:NO];
            }
        }
        else if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_DETAILS]) {
            NSLog(@"You chose action 2.");
            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:userInfo];
            } else {
                [self navigatateAsPerPush:userInfo allowInActiveState:NO];
            }
        }
    } else  if ([[[userInfo objectForKey:@"aps"] objectForKey:kCategory] isEqualToString:KNotificatoin_IDENTIFIER_NOTIFICATION_REQUEST]){

        NSMutableDictionary *dictData = [NSMutableDictionary dictionaryWithDictionary:userInfo];

        if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_EDIT_REQUEST]) {
            NSLog(@"You chose action 1.");
            [dictData setObject:@16 forKey:kType];
            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:dictData];
            } else {
                [self navigatateAsPerPush:dictData allowInActiveState:NO];
            }

        }
        else if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_MORE_BIDS]) {
            NSLog(@"You chose action 2.");
            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:dictData];
            } else {
                [self navigatateAsPerPush:dictData allowInActiveState:NO];
            }

        }

    }

    if (completionHandler) {
        completionHandler();
    }
}

Hope it is helpful to you

@Swarup Yes user might not click on any of buttons You have to handle this thing. Try to debug where is your app is crashing — Prashant Tukadiya, Dec 28 '17 at 04:40
Hi @Prashant yes have to handle this thing. Can I disable user interaction when user click notification body(apart from 2buttons click)? — Swarup, Dec 28 '17 at 05:55
@Swarup Nope !! You can't , If use don't click on any button you should handle this response as per either button 1 or button 2 — Prashant Tukadiya, Dec 28 '17 at 05:57

With the iOS 12 SDK, your app take advantage of Interactive Controls in Notifications

Notification content app extensions now support user interactivity in custom views. If the content of your app’s notifications needs to prompt user interaction, add controls like buttons and switches.

To enable user interactions:

Open your Notification Content Extension’s info.plist file.

Add the UNNotificationExtensionUserInteractionEnabled key to your extension attributes. Give it a Boolean value, set to YES.
