1. 带UI的通讯录

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

@interface ViewController ()<ABPeoplePickerNavigationControllerDelegate>
@end

@implementation ViewController
// 触摸显示
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    //1. 创建联系人选择控制器
    ABPeoplePickerNavigationController *picker = [ABPeoplePickerNavigationController new];
    
    //2. 设置代理 --> 注意不是 Delegate
    picker.peoplePickerDelegate = self;
    
    //3. 模态视图弹出
    [self presentViewController:picker animated:YES completion:nil];
}

#pragma mark 选中某个联系人时调用
/**
 以下两个方法,如果同时实现, 只会运行didSelectPerson: 方法
 两个方法, 应该实现一个即可
 */

- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person
{
    //需求: 获取姓名 和 电话
    
    //1. 获取姓名
    //Record --> 就相当于一条记录
    //lastName: 姓
    CFStringRef lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
    NSString *lastNameStr = (__bridge NSString *)(lastName);
    NSLog(@"lastNameStr: %@",lastNameStr);
    
    CFStringRef firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSString *firstNameStr = (__bridge NSString *)(firstName);
    NSLog(@"firstNameStr: %@",firstNameStr);
    
    CFRelease(lastName);
    CFRelease(firstName);
    
    //2. 获取电话 --> 电话是多数据类型
    ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);

    //1. 有几种方式 2. 注意事项 注意释放 CF 对象
    //将 CF 对象给 Foundatian
   
    //1. (__bridge type)<#expression#>) : 只是让 Foundation 框架暂时使用 CF 框架对象
    //2. (__bridge_transfer )) / CFBridgingRelease : CF框架移交对象的管理权给 Foundation 框架
    //将 Foundatian给 CF 对象 不常用
    //3. (__bridge_retained <#CF type#>)<#expression#>)
}

#pragma mark 选中联系人的某个属性的时候调用

//- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
//{
//    NSLog(@"%d",property);
//}

#pragma mark 取消选中联系人时调用
// 在 iOS7下, 必须实现此方法, 否则就会崩溃
//- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
//{
//    NSLog(@"%s",__func__);
//}

2. 不带UI的通讯录

1). AppDelegate授权

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //通讯录授权 --> iOS6开始, 必须授权才能上架
    /**
     kABAuthorizationStatusNotDetermined = 0   用户未选择
     kABAuthorizationStatusRestricted,         一些许可配置阻止了通讯录的交互
     kABAuthorizationStatusDenied,             用户拒绝
     kABAuthorizationStatusAuthorized          用户授权
     */

    //1. 获取授权状态
    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
    
    //2. 创建 AddrssBook
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
    
    //3. 没有授权时就授权
    if (status == kABAuthorizationStatusNotDetermined) {
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            //3.1 判断出错
            if (error) {
                return;
            }
            
            //3.2 判断是否授权
            if (granted) {
                NSLog(@"已经授权");
            } else {
                NSLog(@"没有授权");
            }
        });
    }
    
    //4. 释放 CF 对象
    CFRelease(addressBook);
    return YES;
}

2). 代码

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

@implementation ViewController
// 触摸显示
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    // 点击屏幕获取所有联系人信息
    
    //1. 判断是否授权成功, 授权成功才能获取数据
    if ( ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
     
        //2. 创建通讯录
        ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
        
        //3. 获取联系人  --> Array
        CFArrayRef peosons = ABAddressBookCopyArrayOfAllPeople(addressBook);
        
        //4. 遍历联系人来获取数据(姓名和电话)
        CFIndex count = CFArrayGetCount(peosons);
        
        for (CFIndex i = 0 ; i < count; i++) {
            
            //5. 获取单个联系人
            ABRecordRef person = CFArrayGetValueAtIndex(peosons, i);
            
            //6. 获取姓名
            NSString *lastName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty));
            NSString *firstName  = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));
            NSLog(@"lastName: %@, firstName: %@", lastName, firstName);

            for (CFIndex i = 0; i < phoneCount; i++) {

                NSString *value = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phones, i));
                NSLog(@"label: %@, value: %@",label, value);
            }
            
            NSLog(@"\n\n");
            
            //8.1 释放 CF 对象
            CFRelease(phones);
        }       
        //8.1 释放 CF 对象
        CFRelease(peosons);
        CFRelease(addressBook);
    }
}

3. iOS9 通讯录(新增)

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

@interface ViewController () <CNContactPickerDelegate>
@end

@implementation ViewController

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    // 1. 创建控制器
    CNContactPickerViewController *contact = [CNContactPickerViewController new];
    // 2. 设置代理
    contact.delegate = self;
    // 3. 模态弹出
    [self presentViewController:contact animated:YES completion:nil];
}

#pragma mark 选择联系人的时候调用
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact {
    // 1. 获取姓名
    NSLog(@"givenName: %@, familyName: %@", contact.givenName, contact.familyName);
    // 2. 获取电话
    for (CNLabeledValue *labeledValue in contact.phoneNumbers) {
        CNPhoneNumber *phoneNumber = labeledValue.value;
        NSLog(@"phoneNumber: %@", phoneNumber.stringValue);
    }
}

#pragma mark 实现了此方法就可以选择多个联系人
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact *> *)contacts {
    for (CNContact *contact in contacts) {
        
        NSLog(@"givenName: %@, familyName: %@", contact.givenName, contact.familyName);
        for (CNLabeledValue *labeledValue in contact.phoneNumbers) {
            NSLog(@"label: %@", labeledValue.label);
            CNPhoneNumber *phoneNumber = labeledValue.value;
            NSLog(@"phoneNumber: %@", phoneNumber.stringValue);
        }
    }
}
