Question

I need to be able to format an existing NSString into a different date format. NSDateFormatter has dateFromString and stringFromDate methods, but no stringFromString. Is it possible to take a date that I have in the form of an NSString and reformat it using something similar to:

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];     [dateFormatter setDateFormat:@'yyyy-MM-dd'];     strMyDate = [dateFormatter stringFromString(does not exist):strMyDate];

You need to create a date from the string, then reformat that date into a different string.

Something like:

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];  // get NSDate from old string format [dateFormatter setDateFormat:@'yyyy-MM-dd']; NSDate *date = [dateFormatter dateFromString:@'2009-03-18' ];  // get string in new date format [dateFormatter setDateFormat:@'dd-MM-yyyy']; NSString *strMyDate= [dateFormatter stringFromDate:date];
