i am impliment this code for custom local notification may be helping you where Accept is identifier where you get in delegates of local notification in appDelegate.m

    NSString *idetnt = @"Accept";
    NSString *idetnt1 = @"Reject";
    NSString *idetnt2 = @"Local Notification";
    UIMutableUserNotificationAction *notificationAction1 = [[UIMutableUserNotificationAction alloc] init];
    notificationAction1.identifier = idetnt;
    notificationAction1.title = @"Snooze";
    notificationAction1.activationMode = UIUserNotificationActivationModeBackground;
    notificationAction1.destructive = NO;
    notificationAction1.authenticationRequired = NO;

    UIMutableUserNotificationAction *notificationAction2 = [[UIMutableUserNotificationAction alloc] init];
    notificationAction2.identifier = idetnt1;
    notificationAction2.title = @"Call";
    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:600];
    localNotification.alertBody = idetnt2;
    localNotification.category = @"Email";
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

when ur app in background then this methods call

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler
{ 
   if ([identifier isEqualToString:@"Accept"])
   {
   }
   else if ([identifier isEqualToString:@"Reject"])
   {
   }
   else if ([identifier isEqualToString:@"Reply"])
   {

   }
   if(completionHandler != nil)
    completionHandler();
 }

when ur app in foreground then this methods call

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)localNotification
{
}

Go to capability option and click on remote notification

您无法添加完全自定义，但您的通知可以设置category属性以指定应使用哪些通知设置，并且这些通知设置可以指定要显示的按钮以及用户选择这些按钮时的按钮。
