IOS中的日期时间/字符串格式

Question

我有一个NSString,这是这段代码中的日期和时间:"YYYY-MM-DD HH:mm:SS"我希望它像德国风格一样:"DD.MM.YYY HH:mm:DD"

怎么解决？

Answer 1

将一个日期字符串转换为另一种格式的示例:

NSString*currentDateString = @"04-08-2012 08:16:00";

NSLog(@"currentDateString: %@", currentDateString);

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

[dateFormater setDateFormat:@"MM-DD-yyyy HH:mm:ss"];
NSDate *currentDate = [dateFormater dateFromString:currentDateString];
NSLog(@"currentDate: %@", currentDate);

[dateFormater setDateFormat:@"yyyy-MM-DD HH:mm:ss"];
NSString *convertedDateString = [dateFormater stringFromDate:currentDate];
NSLog(@"convertedDateString: %@", convertedDateString);

[dateFormater setDateFormat:@"DD.MM.yyy HH:mm:DD"];
NSString *germanDateString = [dateFormater stringFromDate:currentDate];
NSLog(@"germanDateString: %@", germanDateString);

NSLog输出:
currentDateString:04-08-2012 08:16:00
currentDate:2012-04-01 12:16:00 +0000
convertedDateString:2012-04-92 08:16:00
germanDateString:92.04.2012 08:16: 92
