iOS获取联系人信息

iOS 9.0之前

- (void)fetchAddressBookBeforeIOS9{
    ABAddressBookRef addressBook = ABAddressBookCreate();
    //首次访问需用户授权
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {//首次访问通讯录
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            if (!error) {
                if (granted) {//允许
                    NSLog(@"已授权访问通讯录");
                    NSArray *contacts = [self fetchContactWithAddressBook:addressBook];
                    dispatch_async(dispatch_get_main_queue(), ^{
                        //----------------主线程 更新 UI-----------------
                        NSLog(@"contacts:%@", contacts);
                    });
                }else{//拒绝
                    NSLog(@"拒绝访问通讯录");
                }
            }else{
                NSLog(@"发生错误!");
            }
        });
    }else{//非首次访问通讯录
        NSArray *contacts = [self fetchContactWithAddressBook:addressBook];
        dispatch_async(dispatch_get_main_queue(), ^{
            //----------------主线程 更新 UI-----------------
            NSLog(@"contacts:%@", contacts);
        });
    }
}

- (NSMutableArray *)fetchContactWithAddressBook:(ABAddressBookRef)addressBook{
    if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {////有权限访问
        //获取联系人数组
        NSArray *array = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
        NSMutableArray *contacts = [NSMutableArray array];
        for (int i = 0; i < array.count; i++) {
            //获取联系人
            ABRecordRef people = CFArrayGetValueAtIndex((__bridge ABRecordRef)array, i);
            //获取联系人详细信息,如:姓名,电话,住址等信息
            NSString *firstName = (__bridge NSString *)ABRecordCopyValue(people, kABPersonFirstNameProperty);
            NSString *lastName = (__bridge NSString *)ABRecordCopyValue(people, kABPersonLastNameProperty);
            ABMutableMultiValueRef *phoneNumRef = ABRecordCopyValue(people, kABPersonPhoneProperty);
            NSString *phoneNumber =  ((__bridge NSArray *)ABMultiValueCopyArrayOfAllValues(phoneNumRef)).lastObject;
            [contacts addObject:@{@"name": [firstName stringByAppendingString:lastName], @"phoneNumber": phoneNumber}];
        }
        return contacts;
    }else{//无权限访问
        NSLog(@"无权限访问通讯录");
        return nil;
    }
}

iOS 9.0之后(两种方式)

一：通过代码就可以获取所有通讯录信息(需要用户授权)

获取用户授权
申请使用通讯录，在无权限时提示用户打开权限
导入 #import <Contacts/Contacts.h>

- (IBAction)getMailListAction:(id)sender {
    
    CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    if (status == CNAuthorizationStatusNotDetermined) {
        CNContactStore *store = [[CNContactStore alloc] init];
        [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError*  _Nullable error) {
            if (error) {
                //无权限
                [self showAlertViewAboutNotAuthorAccessContact];
            } else {
                //有权限
                [self openContact];
            }
        }];
    } else if(status == CNAuthorizationStatusRestricted) {
        //无权限
        [self showAlertViewAboutNotAuthorAccessContact];
    } else if (status == CNAuthorizationStatusDenied) {
        //无权限
        [self showAlertViewAboutNotAuthorAccessContact];
    } else if (status == CNAuthorizationStatusAuthorized) {
        //有权限
        [self openContact];
    }
    
}

- (void)showAlertViewAboutNotAuthorAccessContact{
    
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"请授权通讯录权限" message:@"请在iPhone的\"设置-隐私-通讯录\"选项中,允许花解解访问你的通讯录" preferredStyle: UIAlertControllerStyleAlert];
    UIAlertAction *OKAction = [UIAlertAction actionWithTitle:@"好的" style:UIAlertActionStyleDefault handler:nil];
    [alertController addAction:OKAction];
    [self presentViewController:alertController animated:YES completion:nil];
}

// 获取所有联系人信息
- (void)openContact{
    
    NSArray *keysToFetch = @[CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey];
    CNContactFetchRequest *fetchRequest = [[CNContactFetchRequest alloc] initWithKeysToFetch:keysToFetch];
    CNContactStore *contactStore = [[CNContactStore alloc] init];
    
    [contactStore enumerateContactsWithFetchRequest:fetchRequest error:nil usingBlock:^(CNContact * _Nonnull contact, BOOL * _Nonnull stop) {
        
        NSString * firstName = contact.familyName;
        NSString * lastName = contact.givenName;
        
        //电话
        NSArray * phoneNums = contact.phoneNumbers;
        CNLabeledValue *labelValue = phoneNums.firstObject;
        NSString *phoneValue = [labelValue.value stringValue];
        
        NSLog(@"姓名：%@%@ 电话：%@", firstName, lastName, phoneValue);
        
    }];
}

二：打开通讯录选择界面，单选或者多选联系人，以获取信息(无需用户授权)

1. 打开通讯录界面

#import <ContactsUI/ContactsUI.h>
#import <Contacts/Contacts.h>

@interface ViewController () <CNContactPickerDelegate>

@end

@implementation ViewController {
    CNContactPickerViewController * _peoplePickVC;
}

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

- (IBAction)openMailListAction:(id)sender {
    _peoplePickVC = [[CNContactPickerViewController alloc] init];
    _peoplePickVC.delegate = self;
    [self showViewController:_peoplePickVC sender:nil];
}

注意 CNContactPickerViewController 对象需要定义为全局变量。

2. 获取单个联系人信息

// 获取指定联系人 里面只log了第一个电话号码
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact {

    //姓名
    NSString * firstName = contact.familyName;
    NSString * lastName = contact.givenName;

    //电话
    NSArray * phoneNums = contact.phoneNumbers;
    CNLabeledValue *labelValue = phoneNums.firstObject;
    NSString *phoneValue = [labelValue.value stringValue];

    NSLog(@"姓名：%@%@ 电话：%@", firstName, lastName, phoneValue);
}

3. 获取单个联系人指定电话

// 获取指定电话
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty {

    //姓名
    NSString * firstName = contactProperty.contact.familyName;
    NSString * lastName = contactProperty.contact.givenName;

    //电话
    NSString * phoneNum = [contactProperty.value stringValue];

    NSLog(@"姓名：%@%@ 电话：%@", firstName, lastName, phoneNum);
}

4. 获取多个联系人信息

//获取多个联系人 里面只log了每个联系人第一个电话号码
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact *> *)contacts {

    //遍历
    for (CNContact * contact in contacts) {

        //姓名
        NSString * firstName = contact.familyName;
        NSString * lastName = contact.givenName;

        //电话
        NSArray * phoneNums = contact.phoneNumbers;
        CNLabeledValue *labelValue = phoneNums.firstObject;
        NSString *phoneValue = [labelValue.value stringValue];

        NSLog(@"姓名：%@%@ 电话：%@", firstName, lastName, phoneValue);

    }
}

• 只可实现一个代理方法，同时实现多个代理方法只会生效一个，导致弹出的联系人选择页面不是你想要的效果。
