CNContactViewController() 的“创建新联系人”和“添加到现有联系人”

Question

使用 ABAddressBook，当我希望用户能够为他们以前从未见过的联系人选择“创建新联系人”和“添加到现有联系人”时，我会创建并显示一个 ABUnknownPersonViewController .

我无法在 CNContacts 框架中复制此功能。在我看来CNContactViewController(forUnknownContact: contact) 可以工作，但不幸的是，这只允许用户“发送消息”或“共享联系人”。

如何允许用户在 CNContacts 中将联系人作为新联系人或现有联系人的一部分保存到他们的通讯录中？

func presentContact() {

    let status = CNContactStore.authorizationStatusForEntityType(.Contacts)

    switch status {
    case .Authorized: ()
    case .NotDetermined: requestAccess()
    case .Denied, .Restricted: accessDenied()
    }

    print("authorized? \(status == .Authorized)") //prints "authorized? true"

    let unknown = CNContactViewController(forUnknownContact: contact!)

    unknown.delegate = self

    self.navigationController?.pushViewController(unknown, animated: false)

}

即使我尝试请求访问权限，用户仍然无法保存联系人。

您一直没有显示您的真实代码，因此无法为您提供帮助。所以我失去了兴趣。我将向您展示我的真实代码，然后让您研究它并思考我正在做的事情和您正在做的事情之间的区别。这是实际的工作代码；去吧，照样做：

let con = CNMutableContact()
con.givenName = "Johnny"
con.familyName = "Appleseed"
con.phoneNumbers.append(CNLabeledValue(
    label: "woods", value: CNPhoneNumber(stringValue: "555-123-4567")))
let unkvc = CNContactViewController(forUnknownContact: con)
unkvc.message = "He knows his trees"
unkvc.contactStore = CNContactStore()
unkvc.delegate = self
unkvc.allowsActions = false
self.navigationController?.pushViewController(unkvc, animated: true)

CNContactStore *store = [[CNContactStore alloc] init];
CNMutableContact *contact = [[CNMutableContact alloc] init];
CNPhoneNumber * number  = [[CNPhoneNumber alloc] initWithStringValue:@"1234567890"];
CNLabeledValue * labelValue = [[CNLabeledValue alloc]initWithLabel:CNLabelPhoneNumberMobile value:number];
NSMutableArray<CNLabeledValue *> *phoneNumbers = [NSMutableArray new];
[phoneNumbers addObject:labelValue];
contact.phoneNumbers = phoneNumbers;
CNContactViewController *controller = [CNContactViewController viewControllerForNewContact:contact];

controller.contactStore = store;
controller.delegate = self;

[self presentViewController:[[UINavigationController alloc] initWithRootViewController:controller] animated:YES completion:nil];

此代码适用于“创建新联系人”，对于“添加到现有联系人”，我们将不得不使用 CNContactPickerViewController

CNContactPickerViewController * picker = [[CNContactPickerViewController alloc] init];
                                    picker.delegate = self;
                                    [self presentViewController:picker animated:YES completion:nil];

以及委托方法中的

- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact
{
    CNContactStore *store = [[CNContactStore alloc] init];
    CNMutableContact *existingContact = [(CNMutableContact*)contact mutableCopy];
    CNPhoneNumber * number  = [[CNPhoneNumber alloc] initWithStringValue:@"1234567890"];
    CNLabeledValue * labelValue = [[CNLabeledValue alloc]initWithLabel:CNLabelPhoneNumberMobile value:number];
    NSMutableArray<CNLabeledValue *> *phoneNumbers = [NSMutableArray new];
    [phoneNumbers addObject:labelValue];
    [phoneNumbers addObjectsFromArray:existingContact.phoneNumbers];
    existingContact.phoneNumbers = phoneNumbers;
    CNContactViewController *controller = [CNContactViewController viewControllerForNewContact:existingContact];

    controller.contactStore = store;
    controller.delegate = self;

    dispatch_async(dispatch_get_main_queue(), ^
    {
        [self presentViewController:[[UINavigationController alloc] initWithRootViewController:controller] animated:YES completion:nil];
    });

}

虽然它会显示“完成”按钮，而不是“更新”，但它肯定会按照 iPhone 在联系人应用程序中的默认行为执行该功能。

您在代码中缺少的是将unknown 变量的contactStore 属性设置为CNContactStore 的句柄。

[...]

unknown.contactStore = CNContactStore()
