如何在用户的语言环境中获取星期几的名称? [英] How do I get the name of a day of the week in the user's locale?

问题描述

我有一个介于 1 和 7 之间的数字，我想将其转换为用户的区域设置，相当于星期一到星期日.我可以这样做吗?如果可以，怎么做?

I have a number between 1 and 7, which I want to turn into the user's locale's equivalent of Monday to Sunday. Can I do that and if so, how?

推荐答案

一个NSDateFormatter可以给你名字列表:

An NSDateFormatter can give you the list of names:

NSDateFormatter * df = [[NSDateFormatter alloc] init];
[df setLocale: [NSLocale currentLocale]];
NSArray * weekdays = [df weekdaySymbols];

然后您可以像任何其他数组一样对其进行索引 [weekdays objectAtIndex:dayIdx]; 但是请注意，第一个工作日可能因地区而异；具体如何变化(以及关于 NSCalendar 的许多其他内容)在文档中并没有特别清楚地解释.

Which you can then index like any other array [weekdays objectAtIndex:dayIdx]; Be aware, however, that the first weekday may differ by locale; exactly how it may vary (along with many other things about NSCalendar) is not particularly well-explained in the docs.
