Yesterday because the project needs to access the system Address Book to get the phone number, so from the ignorance, began to Daoteng, Daoteng an afternoon, finally finished. Write this blog is to record, the next time you do not make a mistake. At the same time, I have the same rookie can avoid a detour.Well, to get started, to access the system's address book,
