I'm trying to create an app with a custom interface for searching through one's addressbook. Searching the local addressbook seems easy, but I cannot figure out how to search for a person/record in an Exchange addressbook source (i.e. ABSourceType == kABSourceTypeExchangeGAL). I'm using the following code to find the Exchange addressbook source and query it, but I only ever get back an empty array. I understand asking for the entire list of people in an Exchange addressbook cannot possibly return all entries, but I would expect some subset of that list when I query it. Again, instead I get an empty array.
How do you search for contacts in an Exchange addressbook source?
#define CFNIL(x) if(x){CFRelease(x); x=nil;}
//code
ABAddressBookRef _addressbook = ABAddressBookCreate();
CFArrayRef allSources = ABAddressBookCopyArrayOfAllSources(_addressbook);
ABRecordRef exchangeSource;
for(CFIndex i =0; i<CFArrayGetCount(allSources); i++)
{
ABRecordRef source = (ABRecordRef)CFArrayGetValueAtIndex(allSources, i);
NSNumber *sourceTypeNumber = (NSNumber*)((CFNumberRef)ABRecordCopyValue(source, kABSourceType));
NSString *sourceTypeName = (NSString *)((CFStringRef)ABRecordCopyValue(source, kABSourceNameProperty));
int sourceType = [sourceTypeNumber intValue];
if (sourceType == kABSourceTypeExchangeGAL)
{
exchangeSource = source;
}
[sourceTypeNumber release];
[sourceTypeName release];
}
if(exchangeSource)
{
/*
This finds matches in the local device addressbook
NSArray *people = (NSArray *)ABAddressBookCopyPeopleWithName(_addressbook, CFSTR("joe"));
for(int i=0;i<[people count]; i++)
{
ABRecordRef person = (ABRecordRef)[people objectAtIndex:i];
ABMultiValueRef emails = (ABMultiValueRef)ABRecordCopyValue(person, kABPersonEmailProperty);
NSLog(@"emails: %@",emails);
[((NSArray*)emails) release];
}
[people release];
*/
//this array is always empty
CFArrayRef search = ABAddressBookCopyArrayOfAllPeopleInSource (_addressbook,exchangeSource);
NSLog(@"%@", search);
CFNIL(search);
}
CFNIL(exchangeSource);
CFNIL(_addressbook);
