使用场景

一些App通过手机号码来推荐好友，如 微博、支付宝

首先客户端会获取通讯录中的所有手机号然后将这些手机号提交到App服务器中，服务器会查找每个手机号对应的App账号如QQ号码返回到客户端，然后客户端根据服务器返回的账号列表来推荐好友。

获取联系人方式

• 方案一：AddressBookUI.framework框架
  
  • 提供了联系人列表界面、联系人详情界面、添加联系人界面等
  • 一般用于选择联系人
• 方案二：AddressBook.framework框架：
  
  • 没有提供UI界面，需要自己搭建联系人界面
  • 纯C语言的API， 仅仅是获得联系人数据
  • 大部分数据类型是Core Foundation
  • 从iOS6 开始，需要得到用户的授权才能访问通讯录
• 方案三：第三方框架：RHAddressBook
  
  • 对 AddressBook.framework 进行封装
• 方案四：iOS9.0最新通讯录框架
  
  • ContactsUI.framework : 方案1的替代品，特点： 面向对象，使用简单，有界面
  • Contacts.framework： 方案2的替代品， 特点：面向对象，使用简单，五界面

方案一：AddressBookUI.framework

实现步骤：

1. 创建选择联系人的控制器
2. 设置代理：用来接收用户选择的联系人信息
3. 弹出联系人控制器
4. 实现代理方法
5. 在对应的代理方法中获取联系人信息

AddressBook.frame

实现步骤：

1. 请求授权
2. 判断授权状态如果已授权则继续，如果未授权则提示用户
3. 创建通讯录对象
4. 从通讯录中获取所有的联系人
5. 遍历所有的联系人
6. 释放不再使用的对象

AddreesBook.framework具体实现:

1. AppDelegate 应用启动时请求授权

#import "AppDelegate.h"
#import <AddressBook/AddressBook.h>

@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 {
    // 判断是否授权
    ABAuthorizationStatus authorizationStatus = ABAddressBookGetAuthorizationStatus();
    if (authorizationStatus == kABAuthorizationStatusNotDetermined) {
        // 请求授权
        ABAddressBookRef addressBookRef =  ABAddressBookCreate();
        ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
            if (granted) {  // 授权成功

            } else {        // 授权失败
                NSLog(@"授权失败！");
            }
        });
    }
}
@end

2. iOS10 需要在Info.plist配置NSContactsUsageDescription

<key>NSContactsUsageDescription</key>
<string>请求访问通讯录</string>     

---

3. ViewController

#import "ViewController.h"
#import <AddressBook/AddressBook.h>

@interface ViewController ()

@end

@implementation ViewController

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

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    // 1. 判读授权
    ABAuthorizationStatus authorizationStatus = ABAddressBookGetAuthorizationStatus();
    if (authorizationStatus != kABAuthorizationStatusAuthorized) {

        NSLog(@"没有授权");
        return;
    }

    // 2. 获取所有联系人
    ABAddressBookRef addressBookRef = ABAddressBookCreate();
    CFArrayRef arrayRef = ABAddressBookCopyArrayOfAllPeople(addressBookRef);
    long count = CFArrayGetCount(arrayRef);
    for (int i = 0; i < count; i++) {
        //获取联系人对象的引用
        ABRecordRef people = CFArrayGetValueAtIndex(arrayRef, i);

        //获取当前联系人名字
        NSString *firstName=(__bridge NSString *)(ABRecordCopyValue(people, kABPersonFirstNameProperty));

        //获取当前联系人姓氏
        NSString *lastName=(__bridge NSString *)(ABRecordCopyValue(people, kABPersonLastNameProperty));
        NSLog(@"--------------------------------------------------");

            NSLog(@"phone=%@", phone);
            [phoneArray addObject:phone];
        }

        //获取当前联系人的邮箱 注意是数组

            NSLog(@"email=%@", email);
            [emailArray addObject:email];
        }
//获取当前联系人中间名
        NSString *middleName=(__bridge NSString*)(ABRecordCopyValue(people, kABPersonMiddleNameProperty));

        NSString *birthday=(__bridge NSDate*)(ABRecordCopyValue(people, kABPersonBirthdayProperty));

        //获取当前联系人的备注
        NSString *notes=(__bridge NSString*)(ABRecordCopyValue(people, kABPersonNoteProperty));

        //获取创建当前联系人的时间 注意是NSDate
        NSDate *creatTime=(__bridge NSDate*)(ABRecordCopyValue(people, kABPersonCreationDateProperty));

        //获取最近修改当前联系人的时间
        NSDate *alterTime=(__bridge NSDate*)(ABRecordCopyValue(people, kABPersonModificationDateProperty));

        //获取地址
        ABMultiValueRef address = ABRecordCopyValue(people, kABPersonAddressProperty);
        for (int j=0; j<ABMultiValueGetCount(address); j++) {
            //地址类型

第三方框架：RHAddressBook

---

https://github.com/heardrwt/RHAddressBook

该框架使用的MRC来管理内存的，如果直接将源代码拖入进去需要为每个文件设置编译标记：-fno-objc-arc， 设置完还会报错，该项目使用的一些方法过于古老，很多都不支持了，所以这种方式不采用； 可以将该项目打成静态库的方式；也可以直接将项目拖入到自己的工程中作为一个依赖

1. 直接将RHAddressBook.xcodeproj拖入到工程中
   

2. 添加Target Dependencies和Link Binary With Libraries
   

3. Build Settings—> Other Linker Flags : -ObjC
   用于解决系统分类找不到方法的错误
   

4. iOS10 需要在Info.plist配置NSContactsUsageDescription

<key>NSContactsUsageDescription</key>
<string>请求访问通讯录</string>     

1. App启动时请求授权访问通讯录

#import "AppDelegate.h"
#import <RHAddressBook/RHAddressBook.h>

@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(@"请求授权拒绝");
            }
        }];
    }
}
@end

1. 获取所有联系人的信息：姓名、手机号等

#import "ViewController.h"
#import <RHAddressBook/RHAddressBook.h>
#import <RHAddressBook/AddressBook.h>

@interface ViewController ()

@end

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

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    RHAddressBook *addressBook = [[RHAddressBook alloc] init];
    if ([RHAddressBook authorizationStatus] != RHAuthorizationStatusAuthorized){
        NSLog(@"没有授权");
        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);
        }

        NSLog(@"----------------------------------------------");
    }
}
@end

#import "ViewController.h"
#import <ContactsUI/ContactsUI.h>

@interface ViewController () <CNContactPickerDelegate>

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    CNContactPickerViewController *contactPickerViewController = [[CNContactPickerViewController alloc] init];
    contactPickerViewController.delegate = self;

    [self presentViewController:contactPickerViewController animated:YES completion:nil];
}


// 如果实现该方法当选中联系人时就不会再出现联系人详情界面， 如果需要看到联系人详情界面只能不实现这个方法，
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact {
    NSLog(@"选中某一个联系人时调用---------------------------------");

    [self printContactInfo:contact];
}

// 同时选中多个联系人
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact *> *)contacts {
    for (CNContact *contact in contacts) {
        NSLog(@"================================================");
        [self printContactInfo:contact];
    }
}

- (void)printContactInfo:(CNContact *)contact {
    NSString *givenName = contact.givenName;
    NSString *familyName = contact.familyName;
    NSLog(@"givenName=%@, familyName=%@", givenName, familyName);
    NSArray * phoneNumbers = contact.phoneNumbers;
    for (CNLabeledValue<CNPhoneNumber*>*phone in phoneNumbers) {
        NSString *label = phone.label;
        CNPhoneNumber *phonNumber = (CNPhoneNumber *)phone.value;
        NSLog(@"label=%@, value=%@", label, phonNumber.stringValue);
    }
}
// 注意:如果实现该方法，上面那个方法就不能实现了，这两个方法只能实现一个
//- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty {
//    NSLog(@"选中某个联系人的某个属性时调用");
//}

@end
