How to Implement iOS8 Interactive Notification

Solution 1:

1. First you need to create the notification Action.
2. Second you need to create the notification category and set its actions.You can set for two contexts. UIUserNotificationActionContextDefault or UIUserNotificationActionContextMinimal
3. Third you need to create the notification setting and assign the above categories
4. Fourth step would be to create local notification and assign it the identifier of the category.

UIMutableUserNotificationAction *notificationAction1 = [[UIMutableUserNotificationAction alloc] init];
notificationAction1.identifier = @"Accept";
notificationAction1.title = @"Accept";
notificationAction1.activationMode = UIUserNotificationActivationModeBackground;
notificationAction1.destructive = NO;
notificationAction1.authenticationRequired = NO;

UIMutableUserNotificationAction *notificationAction2 = [[UIMutableUserNotificationAction alloc] init];
notificationAction2.identifier = @"Reject";
notificationAction2.title = @"Reject";
notificationAction2.activationMode = UIUserNotificationActivationModeBackground;
notificationAction2.destructive = YES;
notificationAction2.authenticationRequired = YES;

UIMutableUserNotificationAction *notificationAction3 = [[UIMutableUserNotificationAction alloc] init];
notificationAction3.identifier = @"Reply";
notificationAction3.title = @"Reply";
notificationAction3.activationMode = UIUserNotificationActivationModeForeground;
notificationAction3.destructive = NO;
notificationAction3.authenticationRequired = YES;

UIMutableUserNotificationCategory *notificationCategory = [[UIMutableUserNotificationCategory alloc] init];
notificationCategory.identifier = @"Email";
[notificationCategory setActions:@[notificationAction1,notificationAction2,notificationAction3] forContext:UIUserNotificationActionContextDefault];
[notificationCategory setActions:@[notificationAction1,notificationAction2] forContext:UIUserNotificationActionContextMinimal];

NSSet *categories = [NSSet setWithObjects:notificationCategory, nil];

UIUserNotificationType notificationType = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:notificationType categories:categories];

[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];
localNotification.alertBody = @"Testing";
localNotification.category = @"Email"; //  Same as category identifier
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

Solution 2:

I would like to extend Sourav Gupta's answer a bit. Once you have done up to what Sourav explained, you have to implement the delegates for receiving push notification actions. The delegates are,

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler {

// Handle actions of local notifications here. You can identify the action by using "identifier" and perform appropriate operations

     if(completionHandler != nil)    //Finally call completion handler if its not nil
         completionHandler();
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler {

// Handle actions of remote notifications here. You can identify the action by using "identifier" and perform appropriate operations

     if(completionHandler != nil)    //Finally call completion handler if its not nil
         completionHandler();
}
