Can ABNewPersonViewController be used to edit existing records?

I'm trying to use ABNewPersonViewController to edit an existing record.

I set the displayedPerson property and it shows up fine with all the info.

If I hit Save, everything works as expected. However, if I 开发者_如何学编程hit Cancel, the record is deleted from the Address Book.

The only solution I can think it is deep copying the record and then re-adding it to the Address Book if the user cancels out of the editing dialog. Is there really no better way?

add a custom "Cancel" button to replace the original "cancel" button of ABNewPersonViewController!!
