爲iphone設置nsdate格式

Question

我希望日期格式如下。

2011年4月22日下午1點05分21秒

格式爲毫米/日/年的時間（12小時），PM或AM

什麼是代碼本？

Answer 1

NSDate *date=[NSDate date]; 
    NSDateFormatter *formatter=[[NSDateFormatter alloc]init]; 
    [formatter setDateFormat:@"MM/dd/yyyy hh:mm:ss a"]; 
    NSString *dateOfGame =[formatter stringFromDate:date]; 
    NSLog(@"dateOfGame%@",dateOfGame); 
    [formatter release]; 

Answer 2

檢查NSDateFormatter（和Date Formatting）

MM/dd/yyyy hh:mm:ss a

Answer 3

一些其他類型的

NSDate* date = [NSDate date]; 
NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease]; 
[formatter setDateFormat:@"MM/dd/yyyy"]; 
NSLog(@"date=%@",[formatter stringFromDate:date]);//date=04/22/2011 

[formatter setTimeStyle:NSDateFormatterBehavior10_4]; 
NSLog(@"date=%@",[formatter stringFromDate:date]);// date=1:05:11 PM 

[formatter setTimeStyle:NSDateFormatterBehaviorDefault]; 
NSLog(@"date=%@",[formatter stringFromDate:date]); date= 

[formatter setTimeStyle:NSDateFormatterFullStyle]; 
NSLog(@"date=%@",[formatter stringFromDate:date]); date=1:05:11 PM India Standard Time 

[formatter setTimeStyle:NSDateFormatterLongStyle]; 
NSLog(@"date=%@",[formatter stringFromDate:date]); date=1:05:11 PM GMT+05:30 

[formatter setTimeStyle:NSDateFormatterMediumStyle]; 
NSLog(@"date=%@",[formatter stringFromDate:date]); date=1:05:11 PM 

[formatter setTimeStyle:NSDateFormatterNoStyle]; 
NSLog(@"date=%@",[formatter stringFromDate:date]);date= 

[formatter setTimeStyle:NSDateFormatterShortStyle]; 
NSLog(@"date=%@",[formatter stringFromDate:date]); date=1:05 PM
