我不在我的Mac，但这应该给你一个开始：

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss'"]; NSDate *originalDate = [dateFormatter dateFromString:originalDateString]; [dateFormatter setDateFormat:@"MM' 'DD','yyyy"]; NSString *formattedDateString = [dateFormatter stringFromDate:originalDate]; [dateFormatter release]; 

Answer 2

你应该看看NSDateFormatter的参考文档，它正是你想要的： http : //developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSDateFormatter_Class/Reference/Reference.html

Answer 3

使用这个代码

NSDateFormatter * df = [[NSDateFormatter alloc] init];

[df setDateFormat：@“yyyy-MM-dd hh：mm：ss a”];

NSDate * myDate = [df dateFromString：myDateAsAStringValue];

 On Class where Date format is required (Implementation class) -(void)DateFormatter:stringDateToBeFormatted { NSDate *dateFormatter=[NSDate convertStringToDate:stringDateToBeFormatted]; NSString *requiredDateFormat= [NSDate dateStringWithMediumFormat: dateFromatter]; self.stringDateFormatLable.Text=[NSString stringWithFormat:@"date required %@",requiredDateFormat] } On NSDate Class implementation class +(NSString *)dateStringWithMediumFormat:(NSDate *)date { NSDateFormatter *dateFormatter =[[NSDateFormatter alloc]init]; [dateFormatter setDateStyle:NSDateFormatterMediumStyle]; or [dateFormatter setDateFormat:@"MMM-dd-yyyy"]; return [dateFormatter stringFromDate:date]; } +(NSDate *)convertStringToDate:(NSString *)dateString { NSDateFormatter *dateFormatter= [[NSDateFormatter alloc]init]; [dateFormatter setDateFormat:@"yyyy'-'MM'-'dd'T'hh':'mm':'ss"]; return [dateFormatter dateFromString:dateString]; }
