使用NSDateFormatter转换NSDate

Question

I have a set of dates as NSString s. They are in the next format: 1980/9/26 17:23:00 . The problem is that the month doesn't include a zero for months from 1 to 9. So some of the dates are 1980/9/26 17:23:00 and some are 1980/12/26 17:23:00 . The date formatter either gets a yyyy/mm/dd hh:mm:ss or yyyy/m/dd hh:mm:ss .

Whichever of these two formats I use, I can't format both date types. Here is the code I used by the way:

-(NSString *) convertDate : (NSString *) unformatted
{

//Format the Date
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy/mm/dd hh:mm:ss"];

NSDate *date = [dateFormat dateFromString:unformatted];

//Format the Calendar
NSDateFormatter *f = [[NSDateFormatter alloc] init];
NSCalendar *persian = [[NSCalendar alloc] initWithCalendarIdentifier:@"persian"];
[f setCalendar:persian];
[f setDateStyle:NSDateFormatterLongStyle];

NSString *formattedDate = [f stringFromDate:date];
//Replace english strings with farsi strings
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Farvardin" withString:@"فروردین"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Ordibehesht" withString:@"اردیبهشت"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Khordad" withString:@"خرداد"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Tir" withString:@"تیر"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Mordad" withString:@"مرداد"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Shahrivar" withString:@"شهریور"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Mehr" withString:@"مهر"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Aban" withString:@"آبان"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Azar" withString:@"آذر"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Dey" withString:@"دی"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Bahman" withString:@"بهمن"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"Esfand" withString:@"اسفند"];
formattedDate=[formattedDate stringByReplacingOccurrencesOfString:@"AP" withString:@""];

return formattedDate;
}

Answer 1

You need to use MM for months. Also, you need to use HH for hours. Try this format: yyyy/MM/dd HH:mm:ss .
