使用場景

一些App通過手機號碼來推薦好友，如 微博、支付寶

首先客戶端會獲取通訊錄中的所有手機號然後將這些手機號提交到App服務器中，服務器會查找每個手機號對應的App賬號如QQ號碼返回到客戶端，然後客戶端根據服務器返回的賬號列表來推薦好友。

獲取聯系人方式

方案一：AddressBookUI.framework框架
提供了聯系人列表界面、聯系人詳情界面、添加聯系人界面等 一般用於選擇聯系人 方案二：AddressBook.framework框架：
沒有提供UI界面，需要自己搭建聯系人界面 純C語言的API， 僅僅是獲得聯系人數據 大部分數據類型是Core Foundation 從iOS6 開始，需要得到用戶的授權才能訪問通訊錄 方案三：第三方框架：RHAddressBook
對 AddressBook.framework 進行封裝 方案四：iOS9.0最新通訊錄框架
ContactsUI.framework : 方案1的替代品，特點： 面向對象，使用簡單，有界面 Contacts.framework： 方案2的替代品， 特點：面向對象，使用簡單，五界面

方案一：AddressBookUI.framework

實現步驟：

創建選擇聯系人的控制器 設置代理：用來接收用戶選擇的聯系人信息 彈出聯系人控制器 實現代理方法 在對應的代理方法中獲取聯系人信息

AddressBook.frame

實現步驟：

請求授權 判斷授權狀態如果已授權則繼續，如果未授權則提示用戶 創建通訊錄對象 從通訊錄中獲取所有的聯系人 遍歷所有的聯系人 釋放不再使用的對象

AddreesBook.framework具體實現:

1. AppDelegate 應用啟動時請求授權

#import "AppDelegate.h"
#import 

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    [self requestAuthorizationAddressBook];
    return YES;
}


- (void)requestAuthorizationAddressBook {
    // 判斷是否授權
    ABAuthorizationStatus authorizationStatus = ABAddressBookGetAuthorizationStatus();
    if (authorizationStatus == kABAuthorizationStatusNotDetermined) {
        // 請求授權
        ABAddressBookRef addressBookRef =  ABAddressBookCreate();
        ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
            if (granted) {  // 授權成功

            } else {        // 授權失敗
                NSLog(@"授權失敗！");
            }
        });
    }
}
@end

2. iOS10 需要在Info.plist配置NSContactsUsageDescription

NSContactsUsageDescription
請求訪問通訊錄

3. ViewController

#import "ViewController.h"
#import 

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    // 1. 判讀授權
    ABAuthorizationStatus authorizationStatus = ABAddressBookGetAuthorizationStatus();
    if (authorizationStatus != kABAuthorizationStatusAuthorized) {

        NSLog(@"沒有授權");
        return;
    }

    // 2. 獲取所有聯系人
    ABAddressBookRef addressBookRef = ABAddressBookCreate();
    CFArrayRef arrayRef = ABAddressBookCopyArrayOfAllPeople(addressBookRef);
    long count = CFArrayGetCount(arrayRef);
    for (int i = 0; i < count; i++) {
        //獲取聯系人對象的引用
        ABRecordRef people = CFArrayGetValueAtIndex(arrayRef, i);

        //獲取當前聯系人名字
        NSString *firstName=(__bridge NSString *)(ABRecordCopyValue(people, kABPersonFirstNameProperty));

        //獲取當前聯系人姓氏
        NSString *lastName=(__bridge NSString *)(ABRecordCopyValue(people, kABPersonLastNameProperty));
        NSLog(@"--------------------------------------------------");
        NSLog(@"firstName=%@, lastName=%@", firstName, lastName);

        //獲取當前聯系人的電話 數組
        NSMutaleArray *phoneArray = [[NSMutableArray alloc]init];
        ABMultiValueRef phones = ABRecordCopyValue(people, kABPersonPhoneProperty);
        for (NSInteger j=0; j
4. 運行結果
第三方框架：RHAddressBook
https://github.com/heardrwt/RHAddressBook
該框架使用的MRC來管理內存的，如果直接將源代碼拖入進去需要為每個文件設置編譯標記：-fno-objc-arc， 設置完還會報錯，該項目使用的一些方法過於古老，很多都不支持了，所以這種方式不采用； 可以將該項目打成靜態庫的方式；也可以直接將項目拖入到自己的工程中作為一個依賴
直接將RHAddressBook.xcodeproj拖入到工程中 

添加Target Dependencies和Link Binary With Libraries

請求訪問通訊錄     

App啟動時請求授權訪問通訊錄

#import "AppDelegate.h"
#import 

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    [self requestAuthorizationForAddressBook];
    return YES;
}

- (void)requestAuthorizationForAddressBook {
    RHAddressBook *ab = [[RHAddressBook alloc] init];
    if ([RHAddressBook authorizationStatus] == RHAuthorizationStatusNotDetermined){

        [ab requestAuthorizationWithCompletion:^(bool granted, NSError *error) {
            if (granted) {

            } else {
                NSLog(@"請求授權拒絕");
            }
        }];
    }
}
@end

獲取所有聯系人的信息：姓名、手機號等

#import "ViewController.h"
#import 
#import 

@interface ViewController ()

@end

@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    RHAddressBook *addressBook = [[RHAddressBook alloc] init];
    if ([RHAddressBook authorizationStatus] != RHAuthorizationStatusAuthorized){
        NSLog(@"沒有授權");
        return;
    }

    NSArray *peopleArray= addressBook.people;
    for (int i = 0; i < peopleArray.count; i++) {
        RHPerson *people = (RHPerson *)peopleArray[i];
        NSLog(@"%@", people.name);

        RHMultiStringValue *phoneNumbers = people.phoneNumbers;
        for (int i = 0; i < phoneNumbers.count; i++) {
            NSString* label= [phoneNumbers labelAtIndex:i];
            NSString* value= [phoneNumbers valueAtIndex:i];

            NSLog(@"label=%@, value=%@", label, value);
        }
