Question

这个问题可能有重复

我做了一些R＆amp; D获得这些结果。但是，目前我正在使用XCode 7.3，我只使用Contact Framework而不是ABAddressBook Framework。

使用AddressBook Framework获取周年纪念标签：Anniversary from contacts in iPhone

如何使用“联系人框架”获取这些结果以及生日列表如何？

Answer 1

在获取联系人时添加此密钥以获取生日： -

let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactEmailAddressesKey, CNContactBirthdayKey]

Answer 2

CNContact周年纪念日没有自己的钥匙。如果存在，则它通过[CNLabeledValue<NSDateComponents>]作为日期组件值驻留在联系人的CNContactDatesKey数组中。你必须自己提取它。

以下是抓住它的简短示例：

斯威夫特3：

let store = CNContactStore()
let keys = [CNContactDatesKey as CNKeyDescriptor]
let containerId = store.defaultContainerIdentifier()
let predicate = CNContact.predicateForContactsInContainer(withIdentifier: containerId)

func fetchContacts() -> [CNContact]? {
    do {
        return try store.unifiedContacts(matching: predicate, keysToFetch: keys)
    } catch let error {
        print(error.localizedDescription)
        return nil
    }
}

let contacts = fetchContacts()

// Grab the first contact as an example
if let contact = contacts?.first {
    // Filter through the contact's dates array to find the one labeled "Anniversary"
    let anniversary = contact.dates.filter { date -> Bool in
        guard let label = date.label else { return false }
        return label.contains("Anniversary")
        }.first?.value as? DateComponents

    // The final date
    let date = anniversary?.date
}

Answer 3

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


self.groupOfContacts = [@[] mutableCopy];
[self getAllContact];

self.phoneNumberArr = [@[] mutableCopy];

for (CNContact *contact in self.groupOfContacts) {

    NSArray *thisOne = [[contact.phoneNumbers valueForKey:@"value"] valueForKey:@"digits"];


    // like this way you can pick different info like b'day and anniversary
    [self.phoneNumberArr addObjectsFromArray:thisOne];
}

NSLog(@"%@",self.phoneNumberArr);
NSLog(@"%@",self.groupOfContacts[0]);
// Override point for customization after application launch.
return YES;
}

-(void)getAllContact{


if ([CNContactStore class]) {


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

    NSArray *keysToFetch = @[CNContactBirthdayKey,CNContactNamePrefixKey,CNContactPhoneNumbersKey,CNContactFamilyNameKey,CNContactRelationsKey,CNContactDatesKey];

    CNContactFetchRequest *fetchRequest =  [[CNContactFetchRequest alloc]initWithKeysToFetch:keysToFetch];

    [addressBook enumerateContactsWithFetchRequest:fetchRequest error:nil usingBlock:^(CNContact * _Nonnull contact, BOOL * _Nonnull stop) {
        [self.groupOfContacts addObject:contact];
    }];
}

}

您可以根据要求执行类似此更改键的操作。希望这会有所帮助：）
