在iPhone的地址簿中创建一个组

联系是在不在组中已创建的所有联系人下创建的.以下是我使用过的代码

// create address book record
ABAddressBookRef addressBook = ABAddressBookCreate(); 
// create a person  
ABRecordRef person = ABPersonCreate();  
// first name of the new person
ABRecordSetValue(person,kABPersonFirstNameProperty,@"FirstName",nil);
// his last name 
ABRecordSetValue(person,kABPersonLastNameProperty,@"LastName",nil);  
//add the new person to the record
ABAddressBookAddRecord(addressBook,person,nil); 

ABRecordRef group = ABGroupCreate(); //create a group 
ABRecordSetValue(group,kABGroupNameProperty,@"My Group",&error); // set group's name 
ABGroupAddMember(group,&error); // add the person to the group         
ABAddressBookAddRecord(addressBook,group,&error); // add the group   

//save the record
ABAddressBookSave(addressBook,nil);  

// relase the ABRecordRef  variable
CFRelease(person);
