iOS: 从 CNContact 获取数字密钥

Question

我正在使用 iOS 9 的新联系人框架，但我不知道如何从 CNContact 上的 phoneNumbers 键中获取数字。

对 CNContact 执行 NSLog 我得到以下输出：

<CNContact: 0x14f57e680: identifier=1B39B156-A151-4905-9624-
DB117ACFBADC, givenName=John, familyName=Doe, 
organizationName=CompanyName, phoneNumbers=(
"<CNLabeledValue: 0x154297a40: identifier=3FEB6B0C-7179-4163-93E6-63C156C2F02B,
label=_$!<Mobile>!$_, value=<CNPhoneNumber: 0x155400e00: countryCode=us,
digits=1234567890>>"
), emailAddresses=(
), postalAddresses=(
)>

我可以像这样获取 givenName 和 familyName 的密钥：

CNContact *contact;
[contact valueForKey:@"givenName"]
[contact valueForKey:@"familyName"]

如何获取 phoneNumbers 键下数字的值？

Answer 1

CNContact 有 phoneNumbers 属性。使用它来获取联系人的 phone 号码数组。

CNContact *contact = ...;
NSArray <CNLabeledValue<CNPhoneNumber *> *> *phoneNumbers = contact.phoneNumbers;
CNLabeledValue<CNPhoneNumber *> *firstPhone = [phoneNumbers firstObject];
CNPhoneNumber *number = firstPhone.value;
NSString *digits = number.stringValue; // 1234567890
NSString *label = firstPhone.label; // Mobile

Answer 2

如果您从 CNContactPickerViewController 中选择单个联系人，我有一个更简单的方法将每个 phone 号码从 phone 号码的字典中分离出来 select 联系：-

NSString * phoneHome;
NSString * phoneMobile;
NSString * phoneHomeFax;

for (NSString* phoneNumber in contact.phoneNumbers){
    NSString * phoneLabel = [phoneNumber valueForKey:@"label"];
    if ([phoneLabel rangeOfString:@"Home"].location != NSNotFound){
        phoneHome = [[phoneNumber valueForKey:@"value"] valueForKey:@"digits"];
    }else{
        phoneHome = @"N/A";
    }
    if ([phoneLabel rangeOfString:@"Mobile"].location != NSNotFound){
        phoneMobile = [[phoneNumber valueForKey:@"value"] valueForKey:@"digits"];
    }else{
        phoneMobile = @"N/A";
    }
    if ([phoneLabel rangeOfString:@"HomeFAX"].location != NSNotFound){
        phoneHomeFax = [[phoneNumber valueForKey:@"value"] valueForKey:@"digits"];
    }else{
        phoneHomeFax = @"N/A";
    }
}

NSLog(@"\n Home number = %@ \n Mobile number = %@ \n Home FAX number = %@",phoneHome,phoneMobile,phoneHomeFax);

这样我就可以得到这个作为输出:-

家庭电话是4085553514 手机号码是 N/A 家庭传真号码是 4085553514
