cocoa - 将 NSDate 格式化为年、月、日、时、分、秒的特定样式

Question

我基本上需要分别获取当前日期和时间，格式为:

2009-04-26 
11:06:54

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|

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);

Answer 1

这是我使用的:

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd"];

NSDateFormatter *timeFormat = [[NSDateFormatter alloc] init];
[timeFormat setDateFormat:@"HH:mm:ss"];

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

NSString *theDate = [dateFormat stringFromDate:now];
NSString *theTime = [timeFormat stringFromDate:now];

NSLog(@"\n"
      "theDate: |%@| \n"
      "theTime: |%@| \n"
      , theDate, theTime);

[dateFormat release];
[timeFormat release];
[now release];
