交互式提醒选项在iOS中不可见

Question

I have implemented interactive reminders for local notifications. But those interactive options are visible only when device is unlocked and user pulled down the reminders just after receiving. The first image show just after receiving local notification.

If you swipe it left or right nothing happen. But if you pull down, then you can see the two interactive options. Just like in the second image.

(Q1.) Actually, my first question is why it just show only two options while I have declared three interactive options?

Below is my related code for that.

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

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

UIUserNotificationType types = (UIUserNotificationTypeSound | UIUserNotificationTypeAlert);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:categories];
[application registerUserNotificationSettings:settings];

(Q2.) My second question is, why we can't see interactive options when user swipe the notification in any other stage. (Ex. notification shows under notification center) Please see my next images that I've uploaded.

Answer 1

If using UIUserNotificationActionContextMinimal then notification alert will display no more than 2 custom actions for this context. Docs

On 3D-touch-enabled devices, notification alert actions are available when pulling down the alert or using the 3d-touch gesture. The way you want to view custom actions is available for non 3d-touch devices.
