objective-c - 實現的計步器所獲得的資料與健康APP中的資料不一致，求解。

Question

在呼叫CoreMation框架取得計步資料的時候， 我想取得某一段時間內 每天的計步數的情況。我取得到的數據 和 健康APP中的數據不一樣，請問我這個地方是不是設定的時間不對？我該怎麼設定呢？

下面是我的程式碼和 輸出日誌：

//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];
        }];
    }];

    
}
