iOS通讯录整合，兼容iOS789写法，附demo

苹果的通讯录功能在iOS7,iOS8,iOS9 都有着一定的不同，iOS7和8用的是 <AddressBookUI/AddressBookUI.h> ，但是两个系统版本的代理方法有一些变化，有些代理方法都标注了 NS_DEPRECATED_IOS(2_0, 8_0) 并推荐了另一个代理方法与之对应。  而iOS8到iOS9则是直接弃用了<AddressBookUI/AddressBookUI.h>取而代之的是<ContactsUI/ContactsUI.h>，后者是OC调用，据说当时苹果宣布弃用AddressBookUI还引来了阵阵欢呼。这也就是在使用通讯录功能时得考虑版本各种判断，我也就是工作中遇到了这种坑，然后就顺手兼容封装了一下。希望能解决这个问题。

我觉得通讯录这里的类结构没必要像SDWebImage或是Core Location这样列出来详细去说。大家用到通讯录无外乎就三个功能：

1.点击弹出通讯录页面，选择了一个联系人的电话后直接将信息填到页面输入框内。

2.遍历所有的通讯录数据统一做批量操作，搭建新页面或直接上传。

3.给通讯录写入一条信息。

这里会先对比一下iOS789的写法，最后奉上demo（一个封装后的库，提供了非常便利的api）。不关心内部实现的朋友可以直接拉到demo部分。

一、首先是获取通讯录的权限

iOS7和8保持一致

    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
    ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);
    if (status == kABAuthorizationStatusNotDetermined) {
        NSLog(@"还没问");
        ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error){
            if(granted){
                NSLog(@"点击同意");
            }else{
                NSLog(@"点击拒绝");
            }
        });
    }else if (status == kABAuthorizationStatusAuthorized){
        NSLog(@"已经授权");
        [self loadPerson];
    }else {
        NSLog(@"没有授权");
        // 弹窗提示去获取权限
    }

iOS9及以后调用方法改成

     CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    if (status == CNAuthorizationStatusNotDetermined) {
        [[[CNContactStore alloc]init] requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
            NSLog(@"还没问");
            if(granted){
                NSLog(@"点击了同意");
                [self loadPerson];
            }else{
                NSLog(@"点击了拒绝");
            }
        }];
    }else if (status == CNAuthorizationStatusAuthorized){
         NSLog(@已经授权");
    }else {
        NSLog(@"没有授权");
    }    

二、弹出通讯录选择界面

iOS7的写法如下，代理方法的返回值大多是BOOL类型。

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
    return YES;
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
    ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);
    long index = ABMultiValueGetIndexForIdentifier(phone,identifier);
    NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index);

    CFStringRef lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
    CFStringRef firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);

    NSString *lastname = (__bridge_transfer NSString *)(lastName);
    NSString *firstname = (__bridge_transfer NSString *)(firstName);

    if (phone) {
        [peoplePicker dismissViewControllerAnimated:YES completion:nil];
        return NO;
    }
    return YES;
}

iOS8的代理方法换了，改成了下面两个，但是方法内部的取值基本相同

// 点击了通讯录名字就会退出
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person;

// 点击了名字里面的电话或邮箱才会退出
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier;

至于会调用哪一个方法，可以根据实际需要去选择，在弹出界面的方法中predicateForSelectionOfPerson 这个属性传false就是调用下面的。

    ABPeoplePickerNavigationController *pickervc = [[ABPeoplePickerNavigationController alloc] init];
    pickervc.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false];
    pickervc.peoplePickerDelegate = self;
    [target presentViewController:pickervc animated:YES completion:nil];

iOS9系统下的弹出选择器方法 和 代理方法如下

 // 弹出选择器
- (void)presentPageOnTarget{
     CNContactPickerViewController *contactVc = [[CNContactPickerViewController     alloc] init];
     contactVc.delegate = self;
     [target presentViewController:contactVc animated:YES completion:nil];
}

// 代理方法
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact
{
    SXPersonInfoEntity *personEntity = [SXPersonInfoEntity new];
    NSString *lastname = contact.familyName;
    NSString *firstname = contact.givenName;
    NSLog(@"%@ %@", lastname, firstname);
    personEntity.lastname = lastname;
    personEntity.firstname = firstname;

    NSMutableString *fullname = [[NSString stringWithFormat:@"%@%@",lastname,firstname] mutableCopy];
    [fullname replaceOccurrencesOfString:@"(null)" withString:@"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, fullname.length)];
    personEntity.fullname = fullname;

    NSString *fullPhoneStr = [NSString string];
    NSArray *phoneNums = contact.phoneNumbers;
    for (CNLabeledValue *labeledValue in phoneNums) {
        NSString *phoneLabel = labeledValue.label;
        CNPhoneNumber *phoneNumer = labeledValue.value;
        NSString *phoneValue = phoneNumer.stringValue;
        NSLog(@"%@ %@", phoneLabel, phoneValue);
        if (phoneValue.length > 0) {
            fullPhoneStr = [fullPhoneStr stringByAppendingString:phoneValue];
            fullPhoneStr = [fullPhoneStr stringByAppendingString:@","];
        }
    }
    if (fullPhoneStr.length > 1) {
        personEntity.phoneNumber = [fullPhoneStr substringToIndex:fullPhoneStr.length - 1];
    }
    self.chooseAction(personEntity);
}

这个是点击了名字就直接回调的方法，如果希望点击了属性再回调，则需要加上这一行

contactVc.predicateForSelectionOfContact = [NSPredicate predicateWithValue:false];

// 代理方法调用
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty

三、获取全部通讯录信息

关于批量获取所有通讯录信息的方法有点冗长，这里就不一一贴了，只贴下iOS9的写法，iOS7和8的代码demo里都有。

- (void)printAllPerson
{
    // 获取
    CNContactStore *contactStore = [[CNContactStore alloc] init];
    NSArray *keys = @[CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey];
    CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];

    // 遍历
    [contactStore enumerateContactsWithFetchRequest:request error:nil usingBlock:^(CNContact * _Nonnull contact, BOOL * _Nonnull stop) {
        NSString *lastname = contact.familyName;
        NSString *firstname = contact.givenName;
        NSLog(@"%@ %@", lastname, firstname);
        NSArray *phoneNums = contact.phoneNumbers;
        for (CNLabeledValue *labeledValue in phoneNums) {
            NSString *phoneLabel = labeledValue.label;
            CNPhoneNumber *phoneNumer = labeledValue.value;
            NSString *phoneValue = phoneNumer.stringValue;
            NSLog(@"%@ %@", phoneLabel, phoneValue);
        }
    }];
}

四、写入通讯录

因为写入的话这个功能有点重量级，写入的时候要写入，名字、电话、email、地址等等，这就会使得api过于复杂。暂时我见到过的做法大多都是如果用户给了通讯录权限 那就给你插入一条名字+电话，我做了只有这两个入参的api，当然使用时也完全可以扩展成更多参数的。

iOS7和8

- (void)creatItemWithName:(NSString *)name phone:(NSString *)phone
{
    if((name.length < 1)||(phone.length < 1)){
        NSLog(@"输入属性不能为空");
        return;
    }
    CFErrorRef error = NULL;

    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);
    ABRecordRef newRecord = ABPersonCreate();
    ABRecordSetValue(newRecord, kABPersonFirstNameProperty, (__bridge CFTypeRef)name, &error);

    ABMutableMultiValueRef multi = ABMultiValueCreateMutable(kABMultiStringPropertyType);
    ABMultiValueAddValueAndLabel(multi, (__bridge CFTypeRef)name, kABPersonPhoneMobileLabel, NULL);

    ABRecordSetValue(newRecord, kABPersonPhoneProperty, multi, &error);
    CFRelease(multi);

    ABAddressBookAddRecord(addressBook, newRecord, &error);

    ABAddressBookSave(addressBook, &error);
    CFRelease(newRecord);
    CFRelease(addressBook);
}

iOS9下

- (void)creatItemWithName:(NSString *)name phone:(NSString *)phone
{
    // 创建对象
    // 这个里面可以添加多个电话，email，地址等等。 感觉使用率不高，只提供了最常用的属性：姓名+电话，需要时可以自行扩展。
    CNMutableContact * contact = [[CNMutableContact alloc]init];
    contact.givenName = name?:@"defaultname";
    CNLabeledValue *phoneNumber = [CNLabeledValue labeledValueWithLabel:CNLabelPhoneNumberMobile value:[CNPhoneNumber phoneNumberWithStringValue:phone?:@"10086"]];
    contact.phoneNumbers = @[phoneNumber];

    // 把对象加到请求中
    CNSaveRequest * saveRequest = [[CNSaveRequest alloc]init];
    [saveRequest addContact:contact toContainerWithIdentifier:nil];

    // 执行请求
    CNContactStore * store = [[CNContactStore alloc]init];
    [store executeSaveRequest:saveRequest error:nil];
}

五、我的demo

因为不同版本用的类和枚举都不一样，所以我要设置一个统一的，并且在我的manager中处理各个版本间的判断。 最后开放出来统一的api，只要引入头文件SXAddressBookManager.h 就可以使用这些通用接口了。

①检查当前状态，有两种api

- (void)checkStatus1
{
    SXAddressBookAuthStatus status = [[SXAddressBookManager manager]getAuthStatus];
    if (status == kSXAddressBookAuthStatusNotDetermined) {
        [[SXAddressBookManager manager]askUserWithSuccess:^{
            NSLog(@"点击同意");
        } failure:^{
            NSLog(@"点击拒绝");
        }];
    }else if (status == kSXAddressBookAuthStatusAuthorized){
        NSLog(@"已有权限");
    }else{
        NSLog(@"没有权限");
    }
}

- (void)checkStatus2
{
    [[SXAddressBookManager manager]checkStatusAndDoSomethingSuccess:^{
        NSLog(@"已经有权限，做相关操作，可以做读取通讯录等操作");
    } failure:^{
        NSLog(@"未得到权限，做相关操作，可以做弹窗询问等操作");
    }];
}

②弹出选择窗口，点击回调选中的信息

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [[SXAddressBookManager manager]presentPageOnTarget:self chooseAction:^(SXPersonInfoEntity *person) {
        NSLog(@"%@---%@",person.fullname,person.phoneNumber);
    }];
}

③获得整个通讯录信息

self.personEntityArray = [[SXAddressBookManager manager]getPersonInfoArray];

④往通讯录写入一条信息

[[SXAddressBookManager manager]creatItemWithName:@"雷克萨斯-北京咨询电话" phone:@"010-88657869"];
