Hi, all...
In my iPhone app I'd like to have a text field that duplicates the
behavior of the phone field in the Contacts application, applying a
mask to the field as it's being entered.
So if the user types 2125551212, I'd like the text field to display
(212) 555-1212.
I know about the method
textField:shouldChangeCharactersInRange:replacementString:, which
would enable me to brute force this with lots of code. However, I'd
like to be able to take locale into consideration, so this becomes
non-trivial.
Anyone know of any locale-aware foundation classes that help with
this?
Thx
Steve
I did a little google search just now for 'cocoa phone number
formatter' and found too relevant hits, neither of which appears to be
locale-aware:

Of course, the best solution would be for Apple to provide a locale-
aware NSPhoneNumberFormatter class. May I suggest that you file a
"feature request" entry?
