objective-c - 实现的计步器获取的数据与健康APP中的数据不一致,求解。

在调用CoreMation框架获取计步数据的时候, 我想获取某一段时间内 每天的计步数的情况。我获取到的数据 和 健康APP中的数据不一样,请问我这个地方是不是设置的时间不对?我应该怎么设置呢?

下面是我的代码和 输出日志:

//加载最新数据
- ( void)loadLastestDatas
{
    for (int i = 1; i < 10; i++)
    {
        NSString *dateStr = [NSString stringWithFormat:@"2016-09-0%zd", i];
    
        NSDate *fromDate = [NSDate date];
        fromDate = [DateUtil stringToDate:dateStr dateFormat:@"yyyy-MM-dd"];
    
        NSLog(@"from:%@", fromDate);
        [self addStepsDataWithDate:fromDate];
    }
    [self endRefresh];
    [self.tableView reloadData];
}

- (void)addStepsDataWithDate:(NSDate *)fromDate
{
    WS(ws);
    [self.pedometer queryPedometerDataFromDate:fromDate
                                        toDate:[NSDate dateWithTimeInterval:24*60*60 sinceDate:fromDate]//后一天
                                   withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) {
        
        [[NSOperationQueue mainQueue] addOperationWithBlock:^{
            if (pedometerData == nil) {
                return;
            }
            NSString *str = [NSString stringWithFormat:@"共走了%@步", pedometerData.numberOfSteps];
            [ws.datas addObject:str];
        }];
    }];

    
}
