之前的第一篇文章中介紹了AddressBookUI這個框架，這一篇文章再來看一下AddressBook這個框架论泛，這個框架和前者相比不帶UI揩尸，也就是我們可以從這個框架中獲取到聯(lián)系人相關(guān)數(shù)據(jù)，然后根據(jù)數(shù)據(jù)自定義UI界面屁奏。
使用這個框架的話要進(jìn)行授權(quán)岩榆。在AppDelegate中藥執(zhí)行以下代碼：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //要想訪問通訊錄，iOS10之后要在info.plist加上如下字段
//    <key>NSContactsUsageDescription</key>
//    <string>是否可以訪問通訊錄</string>
    
    //針對AddressBook這個框架坟瓢，自iOS6開始勇边，必選授權(quán)才能上架，否則不能上架
    //獲取授權(quán)狀態(tài)
    /*
     kABAuthorizationStatusNotDetermined = 0, 用戶未選擇
     kABAuthorizationStatusRestricted,         一些許可配置阻止了通訊錄的交互kABAuthorizationStatusDenied,                用戶拒絕kABAuthorizationStatusAuthorized  用戶授權(quán)
     */
    //1.獲取授權(quán)狀態(tài)
    ABAuthorizationStatus state = ABAddressBookGetAuthorizationStatus();
    //2.創(chuàng)建 AddressBook
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
    //3.沒有授權(quán)時才去授權(quán)
    if (state == kABAuthorizationStatusNotDetermined ) {
        //請求授權(quán)
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            //3.1 判斷是否出錯
            if (error) {
                return ;
            }
            //3.2 判斷是否授權(quán)
            if (granted) {
                NSLog(@"已經(jīng)授權(quán)");
            }else{
                NSLog(@"沒有授權(quán)");
            }
        });
    }
    //4.釋放CF對象
    CFRelease(addressBook);
    return YES;
}

接下來看如何獲取聯(lián)系人相關(guān)數(shù)據(jù)折联，和第一篇文章中的部分代碼很類似粒褒，代碼中好友注釋。

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
    //點擊屏幕 獲取所有聯(lián)系人信息
    //1.判斷是否授權(quán)成功诚镰，授權(quán)成功才能獲取數(shù)據(jù)
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
        //2.創(chuàng)建通訊錄
        ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
        //3.聯(lián)系人  --->Array
        CFArrayRef persons = ABAddressBookCopyArrayOfAllPeople(addressBook);
        //4.獲取聯(lián)系人個數(shù)
        CFIndex count = CFArrayGetCount(persons);
        //遍歷聯(lián)系人
        for (CFIndex i = 0; i < count; i++) {
            //5.獲取單個聯(lián)系人數(shù)據(jù)
            ABRecordRef person = CFArrayGetValueAtIndex(persons, i);
            //6.獲取姓名
            NSString *lastName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty));
            NSString *firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));
            NSLog(@"姓：%@   名：%@",lastName,firstName);
            
            //7.獲取電話
            ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
            //7.1 獲取電話個數(shù)  phones.count不可以獲取個數(shù)
            CFIndex count = ABMultiValueGetCount(phones);
            //7.2 遍歷聯(lián)系人
            for (CFIndex i = 0 ; i < count; i++) {
                //7.3 獲取聯(lián)系電話的標(biāo)簽
                //兩種寫法
                NSString *label = (__bridge_transfer NSString *)ABMultiValueCopyLabelAtIndex(phones, i);
                //NSString *label = CFBridgingRelease(ABMultiValueCopyLabelAtIndex(phones, i));
                NSLog(@"電話標(biāo)簽：%@",label);//_$!<Home>!$_
                
                //7.4 獲取聯(lián)系人電話
                NSString *value =(__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, i);
                NSLog(@"電話號碼:%@",value);
            }
            NSLog(@"\n\n");
            //8.釋放CF對象
            CFRelease(phones);
        }
        //8.釋放CF對象
        CFRelease(persons);
        CFRelease(addressBook);
    }else{
        NSLog(@"請前往設(shè)置中更改權(quán)限");
    }
