I know that in iOS 6 we should request the access to contacts first like below :
But now, I wonder how to add detail message in the alert view, just between the alert-title and two buttons. I did see some-app had done that.
I use ABAddressBookCreateWithOptions and ABAddressBookRequestAccessWithCompletion, but the previous one's option is reserved as NULL while the later one only accepts a callback block.
I searched a lot, like another Q, iOS 6 Release Notes and Apple Doc, but failed to make it.
Thanks a lot for any help. :)
