example with zipcode

[mathisonian]

thanks for the updated fork!

I was trying to find an example of using this to input zipcode. I see references to this in

Just add PKView to your application, and it'll take care accepting card numbers, expiry, cvc and zip.

and the example function

- (void) paymentView:(PKView*)paymentView withCard:(PKCard *)card isValid:(BOOL)valid;

in the README references

NSLog(@"Address zip: %@", card.addressZip);

but I can't find any other documentation or instructions on this.
