iOS 6 dateFromString返回错误的日期 [英] iOS 6 dateFromString returns wrong date

问题描述

我最近升级到iOS 6，并且注意到dateFromString无法正常工作，除非我对dateFormat做错了.它在升级之前就可以正常工作.

I recently upgraded to iOS 6 and have noticed dateFromString is not working correctly, unless I'm doing something wrong with my dateFormat. It was working prior to the upgrade.

代码:

NSString *string = @"2012-09-24 - Sun";
NSLog(@"string = %@", string);
NSDateFormatter *df = [[NSDateFormatter alloc] init];
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en-US"];
[df setLocale:locale];
[df setDateFormat:@"yyyy-MM-dd - EEE"];
NSDate *date = [df dateFromString:string];
NSLog(@"date = %@", date);

输出:

string = 2012-09-24 - Sun
date = 1999-12-26 05:00:00 +0000

有什么建议吗?

推荐答案

看起来格式化程序更改了iOS 6中的规范:

Looks like the formatters changed specs in iOS 6:

• OS X v10.8和iOS 6.0中的格式化程序使用版本 tr35- 25 .
• iOS 5.0-5.1中的格式化程序使用版本 tr35-19 .

• Formatters in OS X v10.8 and iOS 6.0 use version tr35-25.
• Formatters in iOS 5.0-5.1 use version tr35-19.
