问题描述

喂！有没有一种方法可以在用户点击按钮时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.

Heyo! Is there a way how when a user taps a button it can add or update a contact into the actual Apple Contacts Book? Some festivals have email responses include a "name card" that the receiver can download and find in their contact book.

推荐答案

如果在 iOS 9 或更高版本中这样做，您应该使用 Contacts 框架:

If doing this in iOS 9 or later, you should use the Contacts framework:

@import Contacts;

您还需要更新您的 Info.plist，添加 NSContactsUsageDescription 来解释为什么您的应用需要访问联系人.

You also need to update your Info.plist, adding a NSContactsUsageDescription to explain why your app requires access to contacts.

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:

Then, when you then want to programmatically add the contact, then you can do something like:

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)，您可以同时导入框架:

Or, even better, if you want to add the contact using the ContactUI framework (giving the user visual confirmation of the contact and let them tailor it as they see fit), you can import both frameworks:

@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];

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

My original answer, using the AddressBook and AddressBookUI frameworks for iOS versions before 9, is below. But if only supporting iOS 9 and later, use the Contacts and ContactsUI frameworks as outlined above.

如果你想在用户的通讯录中添加一个联系人，你使用AddressBook.Framework创建一个联系人，然后你使用AddressBookUI.Framework来呈现允许用户使用 ABUnknownPersonViewController.因此，您可以:

If you want to add a contact to the user's address book, you use AddressBook.Framework to create a contact, and then you use the AddressBookUI.Framework to present the user interface to allow the user to add it to their personal address book using ABUnknownPersonViewController. Thus, you can:

1. 将 AddressBook.Framework 和 AddressBookUI.Framework 添加到 将二进制文件与库链接;

导入 .h 文件:

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

// 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:@"%@
%@", 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);

请参阅 ABUnknownPersonViewController 类参考 或 Prompting the User to Create a New Person Record from Existing Data 地址簿编程指南的部分.
