// 1. 创建选择联系人的控制器
    ABPeoplePickerNavigationController *ppnc = [[ABPeoplePickerNavigationController alloc] init];

// 2. 设置代理(用来接收用户选择的联系人信息)
    ppnc.peoplePickerDelegate = self;

// 3. 弹出联系人控制器
    [self presentViewController:ppnc animated:YES completion:nil];

// 4. 实现代理

    // 1. 选中某个联系人时调用
    - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person
    {

    }

    // 2. 选中某个联系人某个属性时调用
    - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
    {

    }

    // 3. 点击了取消按钮会执行该方法
    - (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
    {

    }

// 5. 在对应的代理方法中获取联系人信息

    // 1. 获取选中联系人的姓名(姓lastname和名firstname)
    CFStringRef firstname = ABRecordCopyValue(person, kABPersonFirstNameProperty);
    CFStringRef lastname = ABRecordCopyValue(person, kABPersonLastNameProperty);
    NSString *firstName = (__bridge_transfer NSString *)(firstname);
    NSString *lastName = (__bridge_transfer NSString *)(lastname);
    NSLog(@"%@ %@", firstName, lastName);

    // 2. 获取联系人的电话号码
    ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
    CFIndex count = ABMultiValueGetCount(phones);
    for (CFIndex i = 0; i < count; i++) {
        NSString *phoneLabel = (__bridge_transfer NSString *)ABMultiValueCopyLabelAtIndex(phones, i);
        NSString *phoneValue = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, i);
            NSLog(@"label : %@ value : %@", phoneLabel, phoneValue);
        }

    // 3. 释放不再使用的对象
    CFRelease(phones);
