问题
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 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?
回答1:
add a custom "Cancel" button to replace the original "cancel" button of ABNewPersonViewController!!
