Question

我尝试将字符串11/08/91（MM / dd / yy）转换为11/08/1991（MM / dd / yyyy），但它输出错误的输出链接 日期是：0091-11-07 18:06:32 +0000

我的原始输出是11/08/1991

我的代码

NSString *strdate = @"11/08/91";

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

[dateformate setDateFormat:@"MM/dd/yyyy"];

NSDate *date = [dateformate dateFromString:strdate];

NSLog(@"Date is :%@",date);

Answer 1

试试这个会给出正确的日期，

  NSString *strdate = @"11/08/91";

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

[dateformate setDateFormat:@"MM/dd/yy"];

NSDate *date = [dateformate dateFromString:strdate];


NSLog(@"Date is :%@",date);

它会给1991-11-07 18:30:00 +0000

然后你可以这样做，

  [dateformate setDateFormat:@"MM/dd/yyyy"];

NSString *str = [dateformate stringFromDate:date];
NSDate *finalDate = [dateformate dateFromString:str];

它会给，

final date str is 11/08/1991

final date is 1991-11-07 18:30:00 +0000

Answer 2

NSString *strdate = @"11/08/91";

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

[dateformate setDateFormat:@"MM/dd/yy"];

NSDate *date = [dateformate dateFromString:strdate];

[dateformate setDateFormat:@"MM/dd/yyyy"];
//date = [dateformate dateFromString:[dateformate stringFromDate:date] ];
NSLog(@"Date is :%@",[dateformate stringFromDate:date]);

输出为：日期是：11/08/1991

将字符串“MM / dd / yy”转换为日期MM / dd / yyyy
