我的应用程序是一个 JSON 代码,其中包含字符串类型的日期.(如2011-10-01").我想知道如何将其转换为 NSDate?它需要以不同的时间格式显示,例如2011 年 10 月 1 日".
My App is a JSON code which involves a date in string type. (Such as "2011-10-01"). I would like to know how I could conver it into NSDate? It needs to be displayed in a different time format such as "1 October, 2011".
例如.此代码不起作用:
ex. this code doesn't work:
NSString *date1 = @"2010-11-12";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MMMM-dd"];
NSDate *date2 = [dateFormat dateFromString:date1];
NSString *strdate = [dateFormat stringFromDate:date2];
正如 Tug 在 他关于这个主题的博文:
Objective-C 和 iOS SDK 提供了一个类来帮助格式化日期(编组和解组),这个类是 NSDateFormatter.不令人惊讶的是,NSDateFormatter 使用 Unicode 日期格式模式.
Objective-C and iOS SDK provide a class to help formatting date (marshaling and unmarshaling), this class is NSDateFormatter. No surprise, the NSDateFormatter uses the Unicode Date Format Patterns.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:@"yyyy-MM-dd"];
NSDate *date = [dateFormatter dateFromString:publicationDate ];
[dateFormatter release];
在这种情况下,publicationDate 是一个 NSString.
where publicationDate in this case is an NSString.
这篇关于Objective-C 字符串(yyyy-mm-dd)到 NSDate的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
