问题描述

我如何将一周中的一天和一天中的时间存储在Objective-C中?

how do I store a day-of-week and time-of-day in objective-c?

即例如相当于7.30pm的WED

i.e. the equivalent of WED's at 7.30pm for example

是否有一个特定的Objective-C对象可以做到这一点?

Is there one specific objective-c object that would do this?

推荐答案

NSDateComponents是一个好的开始，但是NSDateComponents的实例仅在特定的NSCalendar实例的上下文中才有意义，因此您需要研究一下上课这些类一起用于构造(和解构)NSDate对象.

NSDateComponents would be a good start, but an instance of NSDateComponents only makes sense in the context of a particular NSCalendar instance, so you'll want to look into that class, too. Those classes are used together to construct (and deconstruct) NSDate objects.
