Strange NSNumberFormatter crash

Question

The code is simple:

static NSNumberFormatter *numberFormatter = nil;

if (numberFormatter == nil) {
    numberFormatter = [[NSDateFormatter alloc] init];
    [numberFormatter setNumberStyle:NSNumberFormatterDecimalStyle];
}

However, it crashes on the last line:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSDateFormatter setNumberStyle:]: unrecognized selector sent to instance 0x5c378d0'

How is it possible?

There are much worse questions on SO. Otherwise I'd downvote it for you ;) — Dan Rosenstark, Jul 25 '11 at 00:57

Because you created an NSDateFormatter, not an NSNumberFormatter.

Oh my god, I've seen this moment after I posted that to stackoverflow, but sadly I can't delete the post. – Max Yankov Jul 25 '11 at 00:48
