predicate = [NSPredicate predicateWithFormat:@" (perHourStat.originator.company == %@)",selected];

对象：

> Printing description of fetchedObjects: <_PFArray 0x100664fb0>(
> <PerHourStat: 0x1> (entity: PerHourStat; id: 0x10122f310

从/到匹配dateFrom在finder对象中：

> description of from: 2013-02-11 22:00:00 +0000 
> description of to: 2013-02-12 21:59:59 +0000

它看起来像你的日期比较*应*失败，这将解释为什么没有找到对象。 – 2013-02-11 22:43:24

您正在比较同一日期21:00>22:00。这将明显匹配0条记录。
