1.iOS9之前有UI

1.导入第三方的框架

#import 

2.代码实现

#pragma mark - 点击事件
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    // 1.创建选择联系人的控制器
    ABPeoplePickerNavigationController *ppnc = [[ABPeoplePickerNavigationController alloc] init];

    // 2.设置代理
    ppnc.peoplePickerDelegate = self;
    
    // 3.弹出控制器
    [self presentViewController:ppnc animated:YES completion:nil];
}

#pragma mark - 
// 当用户选中某一个联系人时会执行该方法,并且选中联系人后会直接退出控制器
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person
{
    // 1.获取选中联系人的姓名
    CFStringRef lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
    CFStringRef firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
    
    // (__bridge NSString *) : 将对象交给Foundation框架的引用来使用,但是内存不交给它来管理
    // (__bridge_transfer NSString *) : 将对象所有权直接交给Foundation框架的应用,并且内存也交给它来管理
    NSString *lastname = (__bridge_transfer NSString *)(lastName);
    NSString *firstname = (__bridge_transfer NSString *)(firstName);
    NSLog(@"%@ %@", lastname, firstname);
    
    // 2.获取选中联系人的电话号码
    // 2.1.获取所有的电话号码 
    ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
    CFIndex phoneCount = ABMultiValueGetCount(phones);
    
    // 2.2.遍历拿到每一个电话号码
    for (int i = 0; i < phoneCount; i++) {
        // 2.2.1.获取电话对应的key
        NSString *phoneLabel = (__bridge_transfer NSString *)ABMultiValueCopyLabelAtIndex(phones, i);
        
        // 2.2.2.获取电话号码
        NSString *phoneValue = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, i);
        
        NSLog(@"%@ %@", phoneLabel, phoneValue);
    }
    CFRelease(phones);
}

  注意：导入的第三方框架是C语言，使用时防止内存泄漏 需要release

2.iOS9之前没有UI

1.导入第三方框架

#import 

2.在启动app时对用户请求授权

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    /*
     kABAuthorizationStatusNotDetermined = 0,    未决定
     kABAuthorizationStatusRestricted,           由于系统原因,不允许获取用户的通信录
     kABAuthorizationStatusDenied,               拒绝
     kABAuthorizationStatusAuthorized            已经授权
     */
    
    // 1.获取授权状态
    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
    // 2.如果是未决定状态，则请求授权
    if (status == kABAuthorizationStatusNotDetermined) {
        // 2.1.创建通讯录对象
        ABAddressBookRef addressBook = ABAddressBookCreate();
        // 2.2.请求用户的授权
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            if (error) {
                NSLog(@"%@", error);
            }
            if (granted) {
                NSLog(@"授权成功");
            } else {
                NSLog(@"授权失败");
            }
        });
    }
    return YES;
}

3.代码实现

#pragma mark - 点击事件
- (IBAction)open:(id)sender {
    // 1.获取授权状态
    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
    // 2.如果已经授权，才能获取联系人
    if (status != kABAuthorizationStatusAuthorized) return;
    // 3.创建通讯录对象
    ABAddressBookRef addressBook = ABAddressBookCreate();
    // 4.获取所有的联系人
    CFArrayRef peopleArray = ABAddressBookCopyArrayOfAllPeople(addressBook);
    CFIndex peopleCount = CFArrayGetCount(peopleArray);
    // 5.遍历所有的联系人
    for (int i = 0; i < peopleCount; ++i) {
        // 5.1获取某一个联系人
        ABMultiValueRef person = CFArrayGetValueAtIndex(peopleArray, i);
        
        // 5.2获取联系人的姓名
        NSString *lastName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
        NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
        NSLog(@"%@ %@", lastName, firstName);
        
        /// 5.3.获取电话号码
        // 5.3.1.获取所有的电话号码
        ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
        CFIndex phoneCount = ABMultiValueGetCount(phones);
        
        // 5.3.2.遍历拿到每一个电话号码
        for (int i = 0; i < phoneCount; i++) {
            // 1.获取电话对应的key
            NSString *phoneLabel = (__bridge_transfer NSString *)ABMultiValueCopyLabelAtIndex(phones, i);
            
            // 2.获取电话号码
            NSString *phoneValue = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, i);
            
            NSLog(@"%@ %@", phoneLabel, phoneValue);
        }    
        CFRelease(phones);
    }
    CFRelease(addressBook);
    CFRelease(peopleArray);
}
