问题描述

我有一些这种格式的日期:

I have some dates in this format :

2012-06-26 12:00:00 +0000

我想要做的就是将它们转换成这种格式:

and what i want to do is convert them in this format :

Jun 26, 2012 12:00:00 AM

在 obj-c 上是否有一种简单的方法可以做到这一点,或者我必须解析所有核心内容,并为此创建自己的函数?如果是的话,任何想法都会是什么样子,因为我是 iOS 新手.非常感谢您阅读我的帖子:D

Is there an easy way to do this on obj-c , or i must parse everything hardcore , and make my own function for this? If yes , any ideas how this would look like , cause i am new on iOS. Thank you very much for reading my post :D

推荐答案

要将 1 个字符串转换为另一个字符串,请使用以下代码

To convert from 1 string to the other use the following

NSString *inputString = @"2012-06-26 12:00:00 +0000";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy-MM-dd hh:mm:ss z"];//input

NSDate *date = [formatter dateFromString:inputString];

[formatter setDateFormat:@"MMM dd, yyyy hh:mm:ss a"];
NSString *outputString = [formatter stringFromDate:date];
NSLog(@"output : %@",outputString);
