iphone 调用系统通讯录添加联系人

1.通过调用ABNewPersonViewController这个类，有界面，

    ABRecordRef newPerson=ABPersonCreate();

    CFErrorRef error=NULL;

    ABMutableMultiValueRef multiphone=ABMultiValueCreateMutable(kABMultiStringPropertyType);

    ABMultiValueAddValueAndLabel(multiphone, phoneNumber, kABPersonPhoneMobileLabel, NULL);

    ABRecordSetValue(newPerson, kABPersonPhoneProperty,multiphone, &error);

    CFRelease(multiphone);

    

    ABNewPersonViewController* nest = [[ABNewPersonViewController alloc]init];

    nest.newPersonViewDelegate = self;

    nest.displayedPerson=newPerson;

    UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:nest];

    [self.nav presentViewController:nav animated:YES completion:nil];

    CFRelease(newPerson);

    [nest release];

    [nav release];
