将NSDate格式化为年，月，日和小时，分钟，秒的特定样式 [英] Formatting NSDate into particular styles for both year, month, day, and hour, minute, seconds

问题描述

我基本上需要分别获取当前日期和时间，格式为：

I basically need to get current date and time separately, formatted as:

2009-04-26 
11:06:54

下面的代码从同一主题的另一个问题中生成

The code below, from another question on the same topic, generates

now:        |2009-06-01 23:18:23 +0100| 
dateString: |Jun 01, 2009 23:18| 
parsed:     |2009-06-01 23:18:00 +0100|

这几乎是我要找的，但我想分隔日期和时间。

This is almost what I'm looking for, but I want to separate the day and time.

NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"MMM dd, yyyy HH:mm"];

NSDate *now = [[NSDate alloc] init];

NSString *dateString = [format stringFromDate:now];

NSDateFormatter *inFormat = [[NSDateFormatter alloc] init];
[inFormat setDateFormat:@"MMM dd, yyyy"];

NSDate *parsed = [inFormat dateFromString:dateString];

NSLog(@"\n"
"now:        |%@| \n"
"dateString: |%@| \n"
"parsed:     |%@|", now, dateString, parsed);

推荐答案

iPhone格式字符串位于 Unicode format 。

iPhone format strings are in Unicode format. Behind the link is a table explaining what all the letters above mean so you can build your own.

链接后面是一个表格，解释了上面所有的字母是什么意思，所以你可以建立自己的。

And of course don't forget to release your date formatters when you're done with them. The above code leaks format, now, and inFormat.
