Get label names for ABPerson properties

问题

I want to get all label names for properties of ABPerson object. For example: record ABPerson has three phone numbers defined: Mobile, Other, Work. I use labelAtIndex method to get label name but returned string contains needed value wrapped in characters $!!$. Instead of returning just "Mobile" I get these "_$!<" wrap-characters.

I have following code:

//person object points to ABPerson record from addressBook
ABMultiValue *phoneNumbers = [person valueForProperty:kABPhoneProperty];

NSUInteger count = [phoneNumbers count];

for (int i = 0; i < count; i++) {
    NSLog(@"Phone numbers label: %@ value: %@", [phoneNumbers labelAtIndex:i], [phoneNumbers valueAtIndex:i]);        
}

In log I get following:

2012-01-23 01:14:04.234 FixMyAddressBook[3667:707] Phone numbers label: _$!<Mobile>!$_ value: +327382738273
2012-01-23 01:14:04.370 FixMyAddressBook[3667:707] Phone numbers label: _$!<Work>!$_ value: +3293829328

Could someone point me please how can I get label names for properties without special characters?

As far as I'm aware you need to get the localized label for that item, you'll need to make sure you're using the right reference code.

// Grab the right property first
ABMutableMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
CFIndex phoneNumberCount = ABMultiValueGetCount(phoneNumbers);

for(int k = 0; k < phoneNumberCount; k++)
        {

        //Get phone number label by iterating across this
            CFStringRef phoneNumberValue = ABMultiValueCopyValueAtIndex( phoneNumbers, k );

CFStringRef phoneNumberLabel = ABMultiValueCopyLabelAtIndex(phoneNumbers, i);
            CFStringRef phoneNumberLocalizedLabel = ABAddressBookCopyLocalizedLabel( phoneNumberLabel );    
// converts "_$!<Work>!$_" to "work" and "_$!<Mobile>!$_" to "mobile"
//do whatever you want to do here
//release your references
        CFRelease(phoneNumberLocalizedLabel);
CFRelease(phoneNumberValue);
}
