Question

我正在使用iOS 9新的Contact框架，我无法弄清楚如何从CNContact上的phoneNumbers键获取数字。

执行CNContact的NSLog我得到了这个输出：

<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的键：

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

如何获取phoneNumbers键下的数字值？

Answer 1

CNContact具有phoneNumbers属性。用它来获取联系人的电话号码数组。

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中选择单个联系人选择联系人，我有一种更简单的方法可以将每个电话号码与电话号码字典隔离开来： -

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);

这样我就可以将其作为输出： -

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