iOS通讯录 AddressBook框架

• 前言
  iOS通讯录框架有AddressBook,AddressBookUI,Contacts,ContactsUI.
  iOS9 AddressBook,AddressBookUI不推荐使用了，用Contacts,ContactsUI代替。
  如果项目支持到iOS8或以下，还是使用AddressBook,AddressBookUI。本篇只涉及AddressBook框架的4个类。
  可以看到AddressBook包含内容如下图：

• 授权
  首先导入头文件
  #import <AddressBook/AddressBook.h>
  请求授权的代码

//如果用户没决定过，请求授权
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
        //创建通讯录
        ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);
        //请求授权
        ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
            if (granted) {//请求授权页面用户同意授权
                //读取通讯录人员数量,此处不可使用上面请求授权的通讯录对象,会崩溃
                ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
                //获取联系人数量
                CFIndex personCount = ABAddressBookGetPersonCount(addressBook);
                dispatch_async(dispatch_get_main_queue(), ^{
                    //xxx
                });
                CFRelease(addressBook);
            }
         CFRelease(addressBookRef);
//如果是已授权状态
    } else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
        //创建通讯录
        //读取通讯录人员数量
        ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);
        CFIndex personCount = ABAddressBookGetPersonCount(addressBookRef);
        //xxx
        CFRelease(addressBookRef);
    } else {
        [self showAlertWithTitle:@"提醒" message:@"请在设置中打开通讯录授权"];
    }

授权状态一共有四个值，可以自己点击去头文件看一下。为什么release，CoreFoundation框架内存需要手动管理，遇到create，copy，new，retain都需要release。

• 读取联系人信息
  代码：

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
    //拿到所有联系人
    CFArrayRef peopleArray = ABAddressBookCopyArrayOfAllPeople(addressBook);
    //数组数量
    CFIndex peopleCount = CFArrayGetCount(peopleArray);
    for (int i = 0; i < peopleCount; i++) {
        //拿到一个人
        ABRecordRef person = CFArrayGetValueAtIndex(peopleArray, i);
        //拿到姓名
        //姓
        NSString *lastNameValue = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
        //名
        NSString *firstNameValue = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);

        //拿到多值电话
        ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
        //多值数量
        CFIndex phoneCount = ABMultiValueGetCount(phones);
        for (int j = 0; j < phoneCount ; j++) {
            //电话标签本地化(例如是住宅,工作等)
            NSString *phoneLabel = (__bridge_transfer NSString *)ABAddressBookCopyLocalizedLabel(ABMultiValueCopyLabelAtIndex(phones, j));
            //拿到标签下对应的电话号码
            NSString *phoneValue = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, j);
        }
        CFRelease(phones);

        //邮箱多值
        ABMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty);
        CFIndex emailCount = ABMultiValueGetCount(emails);
        for (int k = 0; k < emailCount; k++) {
            NSString *emailLabel = (__bridge_transfer NSString *)ABAddressBookCopyLocalizedLabel(ABMultiValueCopyLabelAtIndex(emails, k));
            NSString *emailValue = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(emails, k);
        }
        CFRelease(emails);
    }
    CFRelease(addressBook);
    CFRelease(peopleArray);

关于__bridge_transfer，是桥接的关键字之一，还有__bridge_retained和__bridge,可以自行搜索桥接如有不明白，关键的是转换对象所有权的问题。

• 新增联系人

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
    for (IABPerson *iPerson in array) {
        //创建一个联系人
        ABRecordRef person = ABPersonCreate();
        //新增姓名
        NSString *Name = iPerson.Name;
        //转换为CFString
        CFStringRef lastName = (__bridge_retained CFStringRef)Name;
        //设置属性
        ABRecordSetValue(person, kABPersonLastNameProperty, lastName, NULL);
        CFRelease(lastName);
        //新增电话
        ABMultiValueRef phones = ABMultiValueCreateMutable(kABMultiStringPropertyType);
            //手机标签设置值
            CFStringRef mobile = (__bridge_retained CFStringRef)iPerson.MobilePhone;
            ABMultiValueAddValueAndLabel(phones, mobile, kABPersonPhoneMobileLabel, NULL);
            CFRelease(mobile);
            //住宅标签设置值
            CFStringRef homeTel = (__bridge_retained CFStringRef)iPerson.HomeTel;
            ABMultiValueAddValueAndLabel(phones, homeTel, kABHomeLabel, NULL);
            CFRelease(homeTel);
            //工作标签设置值
            CFStringRef workTel = (__bridge_retained CFStringRef)iPerson.WorkTel;
            ABMultiValueAddValueAndLabel(phones, workTel, kABWorkLabel, NULL);
            CFRelease(workTel);
            //其他标签设置值
            CFStringRef otherTel = (__bridge_retained CFStringRef)iPerson.OtherTel;
            ABMultiValueAddValueAndLabel(phones, otherTel, kABOtherLabel, NULL);
            CFRelease(otherTel);
        //为联系人的电话多值 设置值
        ABRecordSetValue(person, kABPersonPhoneProperty, phones, NULL);

        //新增邮箱
        ABMultiValueRef emails = ABMultiValueCreateMutable(kABPersonEmailProperty);
            //住宅邮箱设置值
            CFStringRef email = (__bridge_retained CFStringRef)iPerson.Email;
            ABMultiValueAddValueAndLabel(emails, email, kABHomeLabel, NULL);
            CFRelease(email);
        //为联系人添加邮箱多值
        ABRecordSetValue(person, kABPersonEmailProperty, emails, NULL);
        //给通讯录添加联系人
        ABAddressBookAddRecord(addressBook, person, NULL);
        CFRelease(person);
        CFRelease(phones);
        CFRelease(emails);
    }
    //保存通讯录，一定要保存
    ABAddressBookSave(addressBook, NULL);
    CFRelease(addressBook);

这里有一点就是，电话下面的标签，如果你在电话属性下面找

有住宅，工作，其他，但都是传真。其实是在通用下面，因为邮箱也用得到这些标签。
