使用NSDateFormatter发布日期格式 [英] issue with date formatting using NSDateFormatter

问题描述

我有一个日期字符串，我想转换为另一种格式。

I have a date string which I want to convert to another format.

原始日期字符串示例是：
2013-06 -04 02:19:21 +0000

The original date string example is : "2013-06-04 02:19:21 +0000"

我想将其转换为
Wed，Jun 4

NSString * date_string = @"2013-06-04 02:19:21 +0000";

NSDateFormatter *complexdateFormater = [[NSDateFormatter alloc] init];
[complexdateFormater setDateFormat:@"yyyy-M-DD HH:mm:ss Z"];
 NSDate* complexdate = [complexdateFormater dateFromString:date_string];
NSString *formatString = [NSDateFormatter dateFormatFromTemplate:@"EE, MMM d" options:0
                                                          locale:[NSLocale    currentLocale]];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:formatString];
NSString *todayString = [dateFormatter stringFromDate:complexdate];

但上述情况的今天字符串打印出来：
当月为Jan，不管原始字符串中的月份值。

but the today string for the above case prints out : the month as Jan irrespective of the month value in the original string.

我在哪里出错？

推荐答案

这里你去我的朋友

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"EEE, MMM dd"];
    NSString *theDate = [dateFormat stringFromDate:date1];
