iPhone, how do I get the device short date format?

I've not got the device price format setting.

NSNumber *temp = [NSNumber numberW开发者_开发问答ithDouble:dblPrice];
NSDecimalNumber *someAmount = [NSDecimalNumber decimalNumberWithDecimal:[temp decimalValue]];

NSNumberFormatter *currencyFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];

return [currencyFormatter stringFromNumber:someAmount];

How do I get the short date setting ?

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
NSString *dateString = [dateFormatter stringFromDate:[NSDate date]];
