NSDate hebrew date label

问题

I make label with the date for today but I need hebrew date for today.

this my code

NSDate *today = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateStyle:NSDateFormatterShortStyle];
NSString *dateString = [dateFormat stringFromDate:today];
[_label setText:dateString];

I not build calendar this label with date for today.

Assuming the user's current locale is not set for Hebrew, then you need to ensure the date formatter's locale is set for Hebrew,

NSLocale *hebrew = [[NSLocale alloc] initWithLocaleIdentifier:@"he_IL"]; // Hebrew, Israel
NSDate *today = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
dateFormat.locale = hebrew;
[dateFormat setDateStyle:NSDateFormatterShortStyle];
NSString *dateString = [dateFormat stringFromDate:today];
[_label setText:dateString];

That code will still use the calendar for the user's current locale (such a Gregorian). If you also need the Hebrew calendar, then you need this:

NSLocale *hebrew = [[NSLocale alloc] initWithLocaleIdentifier:@"he_IL"]; // Hebrew, Israel
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSHebrewCalendar];
NSDate *today = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
dateFormat.locale = hebrew;
dataFormat.calendar = calendar;
[dateFormat setDateStyle:NSDateFormatterShortStyle];
NSString *dateString = [dateFormat stringFromDate:today];
[_label setText:dateString];
