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]; }]; }]; }
