问题描述

我有以下代码:

[ [NSDate date] descriptionWithLocale: @"yyyy-MM-dd" ]

我希望它返回以下格式的日期:2009-04-23

I want it to return a date in the following format: "2009-04-23"

但它返回:2009年4月23日星期四晚上11:27:03 GMT + 03:00

But it returns: Thursday, April 23, 2009 11:27:03 PM GMT+03:00

我做错了?

提前谢谢。

推荐答案

使用错误的方法。而应尝试 descriptionWithCalendarFormat:timeZone:locale:

You are using the wrong method. Instead try descriptionWithCalendarFormat:timeZone:locale:

[[NSDate date] descriptionWithCalendarFormat:@"%Y-%m-%d"
                                    timezone:nil
                                      locale:nil];

另请注意,该方法的格式与您问题中的格式不同。有关该文档的完整文档,请访问这里

Also note that the method is expecting a different format than the one in your question. The full documentation for that can be found here.

编辑:虽然正如迈克所说,你真的应该使用 NSDateFormatter 。有些问题与Apple在文档中提到的 descriptionWithCalendarFormat:timezone:locale:有关。

Though as Mike noted, you really should be using NSDateFormatter. There are some problems with descriptionWithCalendarFormat:timezone:locale: that Apple mentions in the documentation.
