Use C ++ to access the Symbian phone book

In Symbian OS, the phone book is operated and managed through a default database (contacts. CDB. Therefore, in the Symbian system, you can use the contacts model API to access and manage the phone book. Here, the main class is ccontactdatabase (Database Class, set of all the phone books ), ccontactitem (which represents a separate phone book entry, identified by a unique tcontactitemid. For example, a contact in a phone book), ccontactitemfield (domain class, each phone book entry has many classes, such as Name Domain (epbkfieldidfirstname, epbkfieldidlastname), telephone number domain (epbkfieldidphonenumbergeneral )...).
The series60 developer has extended this model and used the "Phone Book engine". Below are several key classes.

Class cpbkcontactengine

The telephone book engine is implemented through cpbkcontactengine. If a default database already exists, cpbkcontactengine: newl () is connected to the database. Otherwise, the database is created.

Class cpbkcontactitem

The cpbkcontactitem class represents a specific entry in the phone book database, such as a contact. It provides access and search functions for the tpbkcontactitemfield array.

Class tpbkcontactitemfield

Tpbkcontactitemfield is the domain class of a thin phone entry, such as someone's telephone domain or someone's email.

// Haha, I will post a piece of code for accessing the phone book below. I hope you can correct it more.
