iOS9.0之前和之后获取通讯录的方法

1. iOS 9.0之前获取通讯录的方法

- (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;
    }
}

2. iOS 9.0 及 iOS 9.0之后获取通讯录的方法

- (void)fetchAddressBookOnIOS9AndLater{
    //创建CNContactStore对象
    CNContactStore *contactStore = [[CNContactStore alloc] init];
    //首次访问需用户授权
    if ([CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts] == CNAuthorizationStatusNotDetermined) {//首次访问通讯录
        [contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
            if (!error){
                if (granted) {//允许
                    NSLog(@"已授权访问通讯录");
                    NSArray *contacts = [self fetchContactWithContactStore:contactStore];//访问通讯录
                    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 fetchContactWithContactStore:contactStore];//访问通讯录
        dispatch_async(dispatch_get_main_queue(), ^{
            //----------------主线程 更新 UI-----------------
            NSLog(@"contacts:%@", contacts);
            
            
            
        });
    }
}

- (NSMutableArray *)fetchContactWithContactStore:(CNContactStore *)contactStore{
    //判断访问权限
    if ([CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts] == CNAuthorizationStatusAuthorized) {//有权限访问
        NSError *error = nil;
        //创建数组,必须遵守CNKeyDescriptor协议,放入相应的字符串常量来获取对应的联系人信息
        NSArray <id<CNKeyDescriptor>> *keysToFetch = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey];
        //获取通讯录数组
        NSArray<CNContact*> *arr = [contactStore unifiedContactsMatchingPredicate:nil keysToFetch:keysToFetch error:&error];
        if (!error) {
            NSMutableArray *contacts = [NSMutableArray array];
            for (int i = 0; i < arr.count; i++) {
                CNContact *contact = arr[i];
                NSString *givenName = contact.givenName;
                NSString *familyName = contact.familyName;
                NSString *phoneNumber = ((CNPhoneNumber *)(contact.phoneNumbers.lastObject.value)).stringValue;
                [contacts addObject:@{@"name": [givenName stringByAppendingString:familyName], @"phoneNumber": phoneNumber}];
            }
            return contacts;
        }else {
            return nil;
        }
    }else{//无权限访问
        NSLog(@"无权限访问通讯录");
        return nil;
    }
}
