字符串到 NSDate

Question

我正在尝试将字符串转换为日期。已使用以下代码。但是弄错了日期。

谢谢，

NSString *dateString = [NSString stringWithFormat:@"12-07-2011"];
//NSString *dateString = [NSString stringWithFormat:@"%d-%d-%d", selectedDate.day, selectedDate.month, selectedDate.year];
NSLog(@"%@",dateString);

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

[dateFormatter setLocale:[NSLocale currentLocale]];
[dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
[dateFormatter setDateFormat:@"dd-mm-yyyy"];

NSDate* d = [dateFormatter dateFromString:dateString];
NSLog(@"%@",d);               
                      
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Selected Date" message: [NSString stringWithFormat:@"%@",d] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];

Answer 1

问题是您使用的是分钟而不是月份。 M

[dateFormatter setDateFormat:@"dd-MM-yyyy"];
