NSDate - 更改年份值 [英] NSDate - Changing the year value

问题描述

我需要更改NSDate对象。我基本上做的是改变年份值。

I need to change a NSDate object. What I am basically doing is changing the year value.

例如：

NSString *someYear = @"2093";
    NSDate *date = [NSDate date]; // Gets the current date.
    ... Create a new date based upon 'date' but with specified year value.

所以从'init'返回2011-03-06 22:17:50 +0000来自init，我想用2093-03-06 22:17:50 +0000创建一个日期。

So with 'date' returning 2011-03-06 22:17:50 +0000 from init, I would like to create a date with 2093-03-06 22:17:50 +0000.

但是我希望这个文化尽可能保持中立，所以它可以在任何时区工作。

However I would like this to be as culturally neutral as possible, so it will work whatever the timezone.

谢谢。
