iOS - 将联系人添加到联系人中？

Question

喂！ 当用户点击一个按钮时，有没有办法将联系人添加或更新到实际的 Apple Contacts Book 中？一些节日的电子邮件回复包括“名片”，收件人可以下载并在他们的通讯录中找到。

Answer 1

如果在 iOS 9 或更高版本中执行此操作，则应使用 Contacts 框架：

@import Contacts;

您还需要更新您的Info.plist，添加NSContactsUsageDescription 以解释您的应用为什么需要访问联系人。

然后，当您想以编程方式添加联系人时，您可以执行以下操作：

CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusRestricted) {
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Access to contacts." message:@"This app requires access to contacts because ..." preferredStyle:UIAlertControllerStyleActionSheet];
    [alert addAction:[UIAlertAction actionWithTitle:@"Go to Settings" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString] options:@{} completionHandler:nil];
    }]];
    [alert addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:nil]];
    [self presentViewController:alert animated:TRUE completion:nil];
    return;
}

CNContactStore *store = [[CNContactStore alloc] init];

[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
    if (!granted) {
        dispatch_async(dispatch_get_main_queue(), ^{
            // user didn't grant access;
            // so, again, tell user here why app needs permissions in order  to do it's job;
            // this is dispatched to the main queue because this request could be running on background thread
        });
        return;
    }

    // create contact

    CNMutableContact *contact = [[CNMutableContact alloc] init];
    contact.familyName = @"Doe";
    contact.givenName = @"John";

    CNLabeledValue *homePhone = [CNLabeledValue labeledValueWithLabel:CNLabelHome value:[CNPhoneNumber phoneNumberWithStringValue:@"312-555-1212"]];
    contact.phoneNumbers = @[homePhone];

    CNSaveRequest *request = [[CNSaveRequest alloc] init];
    [request addContact:contact toContainerWithIdentifier:nil];

    // save it

    NSError *saveError;
    if (![store executeSaveRequest:request error:&saveError]) {
        NSLog(@"error = %@", saveError);
    }
}];

或者，更好的是，如果您想使用 ContactUI 框架添加联系人（为用户提供联系人的视觉确认，并让他们根据需要进行定制），您可以导入这两个框架：

@import Contacts;
@import ContactsUI;

然后：

CNContactStore *store = [[CNContactStore alloc] init];

// create contact

CNMutableContact *contact = [[CNMutableContact alloc] init];
contact.familyName = @"Smith";
contact.givenName = @"Jane";

CNLabeledValue *homePhone = [CNLabeledValue labeledValueWithLabel:CNLabelHome value:[CNPhoneNumber phoneNumberWithStringValue:@"301-555-1212"]];
contact.phoneNumbers = @[homePhone];

CNContactViewController *controller = [CNContactViewController viewControllerForUnknownContact:contact];
controller.contactStore = store;
controller.delegate = self;

[self.navigationController pushViewController:controller animated:TRUE];

下面是我的原始答案，在 9 之前的 iOS 版本中使用 AddressBook 和 AddressBookUI 框架。但如果只支持 iOS 9 及更高版本，请使用上述Contacts 和ContactsUI 框架。

如果您想将联系人添加到用户的通讯录，请使用AddressBook.Framework 创建联系人，然后使用AddressBookUI.Framework 呈现用户界面以允许用户将其添加到他们的个人地址使用ABUnknownPersonViewController 预订。因此，您可以：

1. 将AddressBook.Framework 和AddressBookUI.Framework 添加到Link Binary With Libraries 下的列表中；

2. 导入 .h 文件：

   #import <AddressBook/AddressBook.h>
   #import <AddressBookUI/AddressBookUI.h>
   

3. 编写创建联系人的代码，例如：

   // create person record
   
   ABRecordRef person = ABPersonCreate();
   
   // set name and other string values
   
   ABRecordSetValue(person, kABPersonOrganizationProperty, (__bridge CFStringRef) venueName, NULL);
   
   if (venueUrl) {
       ABMutableMultiValueRef urlMultiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType);
       ABMultiValueAddValueAndLabel(urlMultiValue, (__bridge CFStringRef) venueUrl, kABPersonHomePageLabel, NULL);
       ABRecordSetValue(person, kABPersonURLProperty, urlMultiValue, nil);
       CFRelease(urlMultiValue);
   }
   
   if (venueEmail) {
       ABMutableMultiValueRef emailMultiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType);
       ABMultiValueAddValueAndLabel(emailMultiValue, (__bridge CFStringRef) venueEmail, kABWorkLabel, NULL);
       ABRecordSetValue(person, kABPersonEmailProperty, emailMultiValue, nil);
       CFRelease(emailMultiValue);
   }
   
   if (venuePhone) {
       ABMutableMultiValueRef phoneNumberMultiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType);
       NSArray *venuePhoneNumbers = [venuePhone componentsSeparatedByString:@" or "];
       for (NSString *venuePhoneNumberString in venuePhoneNumbers)
           ABMultiValueAddValueAndLabel(phoneNumberMultiValue, (__bridge CFStringRef) venuePhoneNumberString, kABPersonPhoneMainLabel, NULL);
       ABRecordSetValue(person, kABPersonPhoneProperty, phoneNumberMultiValue, nil);
       CFRelease(phoneNumberMultiValue);
   }
   
   // add address
   
   ABMutableMultiValueRef multiAddress = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);
   NSMutableDictionary *addressDictionary = [[NSMutableDictionary alloc] init];
   
   if (venueAddress1) {
       if (venueAddress2)
           addressDictionary[(NSString *) kABPersonAddressStreetKey] = [NSString stringWithFormat:@"%@\n%@", venueAddress1, venueAddress2];
       else
           addressDictionary[(NSString *) kABPersonAddressStreetKey] = venueAddress1;
   }
   if (venueCity)
       addressDictionary[(NSString *)kABPersonAddressCityKey] = venueCity;
   if (venueState)
       addressDictionary[(NSString *)kABPersonAddressStateKey] = venueState;
   if (venueZip)
       addressDictionary[(NSString *)kABPersonAddressZIPKey] = venueZip;
   if (venueCountry)
       addressDictionary[(NSString *)kABPersonAddressCountryKey] = venueCountry;
   
   ABMultiValueAddValueAndLabel(multiAddress, (__bridge CFDictionaryRef) addressDictionary, kABWorkLabel, NULL);
   ABRecordSetValue(person, kABPersonAddressProperty, multiAddress, NULL);
   CFRelease(multiAddress);
   
   // let's show view controller
   
   ABUnknownPersonViewController *controller = [[ABUnknownPersonViewController alloc] init];
   
   controller.displayedPerson = person;
   controller.allowsAddingToAddressBook = YES;
   
   // current view must have a navigation controller
   
   [self.navigationController pushViewController:controller animated:YES];
   
   CFRelease(person);

呈现默认联系人控制器

第 1 步： 将 ContactUi.framework 添加到项目中并导入

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

第二步： 添加此代码

 -(void)showAddContactController{
        //Pass nil to show default contact adding screen
        CNContactViewController *addContactVC = [CNContactViewController viewControllerForNewContact:nil];
        addContactVC.delegate=self;
        UINavigationController *navController   = [[UINavigationController alloc] initWithRootViewController:addContactVC];
        [viewController presentViewController:navController animated:NO completion:nil];
    }

第三步：

要在按 DONE 或 CANCEL 时获得回调，请添加 <CNContactViewControllerDelegate> 并实现委托方法。

- (void)contactViewController:(CNContactViewController *)viewController didCompleteWithContact:(nullable CNContact *)contact{
    //You will get the callback here
}

@import Contacts;
-(void)addToContactList
 {
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];

if (status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusRestricted) {

    UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:@"This app previously was refused permissions to contacts; Please go to settings and grant permission to this app so it can add the desired contact" preferredStyle:UIAlertControllerStyleAlert];

    [alert addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]];

    [self presentViewController:alert animated:TRUE completion:nil];

    return;

}

CNContactStore *store = [[CNContactStore alloc] init];

[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {

    if (!granted) {

        dispatch_async(dispatch_get_main_queue(), ^{

            // user didn't grant access;

            // so, again, tell user here why app needs permissions in order  to do it's job;

            // this is dispatched to the main queue because this request could be running on background thread

        });

        return;

    }



    // create contact



    CNMutableContact *contact = [[CNMutableContact alloc] init];

    contact.givenName = @"Test";

    contact.familyName = @"User";

    CNLabeledValue *homePhone = [CNLabeledValue labeledValueWithLabel:CNLabelHome value:[CNPhoneNumber phoneNumberWithStringValue:@"91012-555-1212"]];

    contact.phoneNumbers = @[homePhone];



    CNSaveRequest *request = [[CNSaveRequest alloc] init];

    [request addContact:contact toContainerWithIdentifier:nil];



    // save it



    NSError *saveError;

    if (![store executeSaveRequest:request error:&saveError]) {

        NSLog(@"error = %@", saveError);

    }

}];

 }
