Instance Property


A Boolean value that indicates whether the receiver uses phrases such as “today” and “tomorrow” for the date component.


@property BOOL doesRelativeDateFormatting;


YES if the receiver uses relative date formatting, otherwise NO.

If a date formatter uses relative date formatting, where possible it replaces the date component of its output with a phrase—such as “today” or “tomorrow”—that indicates a relative date. The available phrases depend on the locale for the date formatter; whereas, for dates in the future, English may only allow “tomorrow,” French may allow “the day after the day after tomorrow,” as illustrated in the following example.

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.timeStyle = NSDateFormatterNoStyle;
dateFormatter.dateStyle = NSDateFormatterMediumStyle;
NSLocale *frLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"fr_FR"];
dateFormatter.locale = frLocale;
dateFormatter.doesRelativeDateFormatting = YES;
NSDate *date = [NSDate dateWithTimeIntervalSinceNow:60*60*24*2];
NSString *dateString = [dateFormatter stringFromDate:date];
NSLog(@"dateString: %@", dateString);
// Output
// dateString: après-demain
