Blank field showing up on iPhone AddressBook, how to debug?

Question

The following code creates me an array of all my contacts in my address book by first name and last name. The problem is, I have one contact that keeps showing up with an empty first name and last name. I can't find that contact in my actual address book. Can anyone suggest how to debug this to figure out the source of the mystery ghost contact?

ABAddressBookRef addressBook = ABAddressBookCreate();
NSArray *peopleArray = (NSMutableArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
NSMutableArray *allNames = [NSMutableArray array];

for (id person in peopleArray) {
 NSMutableString *firstName = [(NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty) autorelease];
 NSMutableString *lastName = [(NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty) autorelease];
 ABMutableMultiValueRef multiValueEmail = ABRecordCopyValue(person, kABPersonEmailProperty);
 if (ABMultiValueGetCount(multiValueEmail) > 0) {
  NSString *email = [(NSString *)ABMultiValueCopyValueAtIndex(multiValueEmail, 0) autorelease];
 }

 if (![firstName length]) {
  firstName = @"";
 }
 if (![lastName length]) lastName = @"";

 [allNames addObject:[NSString stringWithFormat:@"%@ %@", firstName, lastName]];
}

The person type is of type NSCFType. I could easily do something like:

 if (![lastName length] && ![firstName length]) continue;

.. and be done with the problem. I'm curious though what entry in my AddressBook is coming up as a ghost. I've tried introspecting the object with gdb, but can't get anything valuable out of it.

I'd like to see all properties for person, but derefing the object to (ABPerson*) doesn't appear to do it.

I've also tried using CFShow(person) that reveals it to be type CPRecord. Can't find further documentation on that, however.

Is there something in gdb I can do to further inspect this particular person object to see where the source of it is coming from?

Answer 1

The entry is probably flagged as an organization record, rather than a person record. In this case you'll have to pull out the organization name rather than the first and last name.

Try looking at the properties for:

kABPersonOrganizationProperty, kABPersonKindProperty

Answer 2

IT is probably a contact that is only an organization

try looking at these properties

These constants implement the person type property (a property of type kABIntegerPropertyType), which indicates whether a person record represents a human being or an organization.

     const ABPropertyID kABPersonKindProperty;
     const CFNumberRef kABPersonKindPerson;
     const CFNumberRef kABPersonKindOrganization;
