iOS本地通知不会第二次触发，但会在获取挂起通知请求中显示

Question

我已经实现了iOS 10本地通知，它对第一个警报有效，但对其他警报无效。我导入了iOS 10库，实现了委托，第一次在委托中接收了它，但它后来没有触发。

我的日期格式为: 2017-05-28 14:04:07 +0000

    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    [calendar setTimeZone:[NSTimeZone localTimeZone]];
    //(NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute)
    NSDateComponents *components = [calendar components:(NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:now];

   NSDate *todaySehri = [calendar dateFromComponents:components];


 UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];

            objNotificationContent.title = [NSString localizedUserNotificationStringForKey:[NSString stringWithFormat:@"Local.."]] arguments:nil];


                  objNotificationContent.body = [NSString localizedUserNotificationStringForKey:@"Incoming Local Notification" arguments:nil];


            objNotificationContent.sound = [UNNotificationSound soundNamed:[NSString stringWithFormat:@"%@",soundFileBtn.titleLabel.text]]; // [UNNotificationSound defaultSound];//soundFileBtn.titleLabel.text;// [UNNotificationSound defaultSound];
            NSDictionary *dict = @{@"alarmID":self.myKey,
                                                   @"SOUND_TYPE":[NSString stringWithFormat:@"%li",(long)self.audio_segment.selectedSegmentIndex]
                                                   };
            NSArray *array = [NSArray arrayWithObjects:dict, nil];
            NSDictionary *data = [NSDictionary dictionaryWithObject:array forKey:@"payload"];


            [objNotificationContent setUserInfo:data];

            //update application icon badge number
            objNotificationContent.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 0);

            NSCalendar *cal = [NSCalendar currentCalendar];

              NSDateComponents *compss= [cal components:(NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute)
                          fromDate:todaySehri];

             UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:compss repeats:NO];

            UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:[todaySehri description]
                                                                                  content:objNotificationContent trigger:trigger];
            //schedule localNotification
            UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
            [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
                if (!error) {
                    NSLog(@"Local Notification succeeded");
                }
                else {
                    NSLog(@"Local Notification failed");
                }
            }];
