将 NSString 格式化为 NSDate

发布于 2024-12-20 05:14:02 字数 510 浏览 2 评论 0原文

我从 facebook 获取用户日期，看起来像

“生日日期” = “1987 年 3 月 4 日” 我写了这段代码

 NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
    [dateFormatter setDateFormat:@"dd/MM/YYYY"];
    NSDate *dateFromString = [dateFormatter dateFromString:birthDate];

    NSLog(@"dateformstring %@ ",dateFromString);
    [birthPicker setDate:dateFromString animated:YES];

和字符串 si 的结果日期：1988-12-25 23:00:00 +0000，我在选择器中选择了这个日期，我不知道这个日期在哪里：/

尝试 [dateFormatter setDateFormat:@"dd/MM/yyyy"];

哎呀。正如 tilo 所说，使用“yyyy”。正如 Apple 文档中所述：

“一个常见的错误是使用 YYYY。yyyy 指定日历年，而 YYYY 指定 ISO 中使用的年份（“一年中的周”）年周日历。”

为此制作了一个 NSString 扩展。

// Simple as this.   
date = dateString.dateValue;

感谢 NSDataDetector，它识别了一大堆格式。

// Tested in GMT+1 (Hungary).
@"2014-01-16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014.01.16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014/01/16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014 Jan 16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014 Jan 16th" dateValue is <2014-01-16 11:00:00 +0000>
@"20140116" dateValue is <2014-01-16 11:00:00 +0000>
@"01-16-2014" dateValue is <2014-01-16 11:00:00 +0000>
@"01.16.2014" dateValue is <2014-01-16 11:00:00 +0000>
@"01/16/2014" dateValue is <2014-01-16 11:00:00 +0000>
@"16 January 2014" dateValue is <2014-01-16 11:00:00 +0000>
@"01-16-2014 17:05:05" dateValue is <2014-01-16 16:05:05 +0000>
@"01-16-2014 T 17:05:05 UTC" dateValue is <2014-01-16 17:05:05 +0000>
@"17:05, 1 January 2014 (UTC)" dateValue is <2014-01-01 16:05:00 +0000>

eppz!kit 的一部分，获取类别 NSString+EPPZKit.h 来自 GitHub。

Made an NSString extension for that.

// Simple as this.   
date = dateString.dateValue;

Thanks to NSDataDetector, it recognizes a whole lot of format.

// Tested in GMT+1 (Hungary).
@"2014-01-16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014.01.16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014/01/16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014 Jan 16" dateValue is <2014-01-16 11:00:00 +0000>
@"2014 Jan 16th" dateValue is <2014-01-16 11:00:00 +0000>
@"20140116" dateValue is <2014-01-16 11:00:00 +0000>
@"01-16-2014" dateValue is <2014-01-16 11:00:00 +0000>
@"01.16.2014" dateValue is <2014-01-16 11:00:00 +0000>
@"01/16/2014" dateValue is <2014-01-16 11:00:00 +0000>
@"16 January 2014" dateValue is <2014-01-16 11:00:00 +0000>
@"01-16-2014 17:05:05" dateValue is <2014-01-16 16:05:05 +0000>
@"01-16-2014 T 17:05:05 UTC" dateValue is <2014-01-16 17:05:05 +0000>
@"17:05, 1 January 2014 (UTC)" dateValue is <2014-01-01 16:05:00 +0000>

Part of eppz!kit, grab the category NSString+EPPZKit.h from GitHub.
